CHLORINATION OF COOLING WATER
GENERAL
In any process where water is used as a coolant,
the water, particularly at elevated temperatures
breeds bacteria and propagates the growth of slime
and algae. The transfer of heat from the process to
the cooling water often occurs in either a (1)
condenser, which consists of tubes through which
the process flows and is surrounded by cooling
water or (2) in a cooling tower, which allows water
to cascade over baffles, exposing the cooling water
to air, thus cooling the water by evaporation. To
keep the heat transfer process operating at
maximum efficiency, the heat exchange surfaces
must be free of slime and algae. Otherwise, the
efficiency of the cooling facility will be severely
impaired.
THE NEED FOR GAS CHLORINATION
Gas chlorination is the preferred method for
controlling slime and algae buildup in cooling water
systems.
In addition, gas chlorination is the
preferred method of controlling microbiological
influenced corrosion (MIC), bio fouling, and fouled
heat exchange surfaces. If the water quality is
maintained in reasonably good condition with a low
chlorine demand to begin with, chlorine is always
the most economical form of treatment. The
chlorine requirement in an individual system is
governed by many factors, such as the quality of
the makeup water, water temperature, air-to-water
ratio, chlorine demand of the water, etc.
GAS CHLORINE APPLICATION
The manner of chlorine feed, whether continuous or
intermittent, depends on the system. For any
system, it is necessary to:
1. Apply sufficient chlorine to obtain the
necessary residual.
2. Maintain this necessary residual for the required
contact time.
Generally, if the chlorination system is to
operate continuously, 1 - 3 PPM dosage is
commonly reported. If the chlorination system will
be used intermittently (shock treatment), dosages
of 3 - 8 PPM have been reported. If product
contamination of the water is a problem, as in a
gasoline refinery, the dosage requirement
may need to be increased accordingly.
The length of the chlorination cycle should
be at least long enough to maintain the desired
chlorine residual for one complete turnover of
water. Many operators add enough chlorine to
maintain a 0.5 - 1.0 PPM free chlorine residual at
the tail end of the condensers, or going to the top of
the towers.
For some cooling towers, two
chlorination cycles per day is sufficient. Other
towers may require additional cycles or continuous
treatment. The typical installation drawings shown
on the other side of this sheet are intended as a
guide only. The drawings show three possible
chlorination application points to consider - intake
water, circulating water, and service water.
Keep in mind the following:
1. All cooling water applications require
control of bacteria, slime, algae, MIC, bio-fouling,
and fouled heat exchange surfaces.
2. Fresh water cooling circuits can take
advantage of short contact times, and the point of
application can be close to the condenser water
tubes.
3. Many operators have stated that a free
chlorine residual of 0.5 - 1.0 PPM at the discharge
of the condensers has been sufficient to control all
slime growths.
4. Chlorination ahead of the cooling water
intake screens can help to control mollusks,
barnacles, sponges, etc.

REGAL™ GAS
CHLORINATORS / SULPHONATORS / AMMONIATORS
Safe/Reliable/Economical
Safety is designed and built into the REGAL.
The REGAL gas chlorinator mounts directly onto the cylinder, which is a major safety factor.
Also, the design and structure of the REGAL mounting yoke is an additional safety feature.
The yoke is built with the heaviest slide bars and tightening bolt in the industry, to ensure
proper alignment and sealing of the lead gasket inlet connection.
Safe
A built-in tightening handle provides just enough leverage to tighten
the yoke and seal the gasket. It will bend before allowing you to exert
enough pressure to accidentally bend the yoke. This prevents the
misalignment of the chlorinator's inlet adapter and the cylinder's
valve, or squeezing the gasket out of the connection. Both of these can
cause gas leaks, and both could happen with competitive units that
require a separate wrench.
An innovative, high strength fluoropolymer coating, bonded to the yoke by an electrofusion
process, gives the REGAL yoke extremely high resistance to corrosion from either chlorine,
sulfur dioxide or ammonia.

REGAL safety extends throughout the entire all-vacuum system.
Chlorine is never under pressure in the REGAL system. A vacuum – created
by water being forced under pressure through the ejector nozzle –
pulls on an extremely tough and resilient diaphragm which pushes
open a spring-loaded inlet safety shut-off valve. The vacuum draws the
gas from the cylinder, through the chlorinator, then through highstrength vacuum tubing into the ejector. There it mixes with the water
that is rushing through the ejector, is carried to the diffuser, which then
passes it into the water being treated.
The ALL VACUUM REGAL SYSTEMS
virtually eliminate the problems
associated with Old Pressure Type
Manifold Systems. The safety and
reliability of REGAL systems has
been proven by years of customer
usage worldwide.
Every surface the gas touches, from the time it leaves the cylinder until
it enters the water, consists of the most advanced, corrosion-resistant
materials available. And there are no supply pressure lines, valves or
fittings to break or corrode.
But most important: should anything happen to cause a break in any
part of the system, gas does not leak out. Air leaks in, and the vacuum
is lost. With no vacuum to pull it open, the powerful spring on the
inlet safety shut-off valve snaps the valve shut, stopping the gas supply
immediately and automatically.
An adjustable feed rate valve and feed rate indicator are built into the
REGAL, to allow the flow of gas to be manually adjusted and observed.

Reliability is also designed and built into the REGAL.
Simplicity is one key to reliability – and the REGAL design is simpler and more efficient
than any other comparable unit. It has only 68 parts – up to 60% fewer than competitive
units. The design is so simple and logical that very little time is needed for learning how to
service it. Only a screwdriver and pliers are needed for servicing.
Another key to reliability is corrosion resistance,
and every one of the REGAL's 68 parts is made
of materials best suited to handle the gas form
of CL2, SO2, or NH3. (Please note: REGAL gas
chlorinators, sulphonators and ammoniators
are all made of different materials and must be
used with the gas for which each is intended). These feeders are designed for gas use only.
The liquid form of these chemicals WILL cause damage to system components. Therefore,
if liquid chemical does enter the system components, contact the factory immediately.
Reliable
Every REGAL is completely hand-assembled by highly skilled technicians who are responsible
for the unit being in perfect condition before it leaves his or her hands.This involves careful
visual inspection at every step of the process and bench testing of the completed unit.
When the assembling technician is completely satisfied with the unit, it is sent to the
REGAL testing room.There it receives a series of stringent tests to a) make sure it has no gas
leaks, b) check its vacuum integrity, and c) measure its operating performance. All these
tests are performed against high-efficiency performance curves, unless the customer has
supplied us with data that enable us to test the system against actual operating conditions
in the intended application.

The REGAL ejector is another factor in the system's reliability and economy.
The ejector performs three of the system's most vital functions:
• It creates the vacuum that pulls the gas from the cylinder. Without
the vacuum, the system will not operate. If the ejector isn't functioning
properly, there is no vacuum.
• It mixes the chlorine, sulfur dioxide or ammonia with the water.
• It keeps water from entering the system.
HOW THE EJECTOR
PRODUCES A VACUUM
Vacuum is created by water under
pressure flowing through a very
efficient, constant differential
The REGAL ejector consists of four components, all of them made of
very strong, special plastic, which enables it to withstand a back-pressure
rating of 200 psig. It can be taken apart for cleaning – and put back
together – in minutes, with no special tools.
venturi in the nozzle. At the
Our nozzle has been designed to produce the highest vacuum at
the lowest pressures and water flow rates. If you need a booster pump
you can use the economical centrifugal type. Because we know that our
single-piece nozzle will never be misaligned and that its operating
characteristics will never change, we can pre-test every one against an
optimum performance curve.
venturi and immediately step back
venturi, there is a pressure drop as
the molecules of water pass at high
speed through the restricted
out to a larger unrestricted area.This
always forms a vacuum as long as
the inlet supply pressure is high
enough to overcome the total
system backpressure.
When the system is shut off, pressure from water flowing through the
nozzle could force water up the same tube through which chlorine
enters when the system is operating – if the ejector did not incorporate
a one-way check valve.
REGAL offers two distinctly different check valves – one for high back
pressures, one for low. Both are designed and built for the highest
reliability, highest performance and lowest maintenance.

REGAL is the most economical because it lasts longer.
WHY TWO CHECK VALVES? BECAUSE COMPROMISES DON'T WORK.
High and low back pressures require entirely different kinds of check valves. REGAL gives
you both. For high pressures, REGAL offers a single piece check valve that utilizes pressure
to close it.
Economical
Where back pressure isn't strong
enough to close the check valve
we've designed a check valve
with a closing spring strong
enough to give a bubble-tight
seal, and a diaphragm with large enough surface area to eliminate any friction loss or
pressure drop across the check valve.
Both check valves are made of materials totally
resistant to chemical attack by both wet and dry
chlorine, sulfur dioxide or ammonia.

REGAL uses an innovative corrosion resistant (dual

can be cleaned and reused indefinitely.

Single-Purpose Low-Pressure Valve
Assures Tight Low-Pressure Seal
RATE VALVE WITH TAPERED OPENING ELIMINATES VALVE SEAT, FOR MORE
ACCURATE SETTINGS – AND LONGER LIFE.
The “seat” used in most rate valves is subject to wear, and is frequently
damaged, particularly at low feed rates.
By eliminating the seat, and relying instead on a tapered opening to
control the flow, we have not only greatly extended the life of the rate
valve, but also increased its accuracy. Rates can be set as easily and
accurately at the bottom end of the metering tube as at the top, and
the maximum feed rate can be changed by merely changing the flow
metering tube. The same rate valve is used for all standard rates up to
100 lbs/day (2 kg/hr).
“Seatless” Rate Valve

The diaphragm and the inlet safety shut-off spring are the two chlorinator parts
most vulnerable to corrosion, but in the REGAL, they are corrosion-proof.
CORROSION-RESISTANT, METALLIC INLET ADAPTER
The inlet adapter is the last point at which the gas is still under pressure
and therefore must be made of a material strong enough to handle the
pressurized gas without being compromised.The REGAL inlet adapter is
made from a special metal alloy that is virtually impervious to attack
by dry, wet, or even liquid chlorine and sulfur dioxide under normal
circumstances and operating conditions.
CORROSION-PROOF, SUPER-STRONG DIAPHRAGM
The diaphragm opens the inlet safety valve to allow the gas to flow, and
maintains a steady flow of gas while the system is in operation. Any
damage to the diaphragm – even a tiny crack or pinhole – would
prevent it from performing these functions. And continuous exposure
to the gas would cause these problems if the REGAL diaphragm were
not twice as thick and three times as strong as its competition, and
made of a plastic that will not corrode.
CORROSION-PROOF, HEAVY DUTY INLET/SAFETY SHUTOFF
VALVE SPRING
Particles small enough to get through the REGAL filter do, in time, build
up on the inlet safety shutoff valve, valve seat and spring. These must
be cleaned periodically. In competitive units this is a tough, time
consuming and costly job. In the REGAL, however, these components
are housed in a capsule that can be removed with just a screwdriver
and pliers, taken apart for cleaning, reassembled, and put back in place,
in less than ten minutes. The heavy duty spring, one of the most critical
parts in any gas chlorinator, carries a LIMITED LIFETIME WARRANTY.
We have placed LIMITED LIFETIME WARRANTIES against corrosion on the diaphragm and inlet safety shut-off spring in all REGAL
chlorinators and sulphonators.
It needs very little servicing, and is easy to take apart for cleaning.
What's true of the system as a whole, is true of every one of its parts.

The same quality, simplicity and ease of maintenance has been developed into ALL
models of REGAL standard units, switchover systems and high capacity gas chlorinators.
REGAL Wall-Mounted Chlorinators For
Multi-Cylinder Chlorination
When larger reserve
and/or feed rate
capacities are needed,
REGAL offers a choice
of wall manifolds
interconnecting one
or more cylinders or
to n co n t a i n e r s to
vacuum regulator(s).
However,because direct
cylinder mounting is
one of the basic safety features of the REGAL, manifolding
does reduce its inherent safety. It also adds the hazards
associated with pressurized flexible connectors.
Manifolding should be avoided if possible.
REGAL Ton-Container Mounting Adapter TAY-200
These adapters make
it possible for users
with continuous feed
rate requirements of
500 ppd or less to
benefit from REGAL
safety, reliability, and
economy, and still
benefit from the lower
gas costs associated
with ton containers.
The REGAL mounts directly on the adapter, with its positive
mounting yoke, and the adapter mounts directly on the ton
container – eliminating the need for hazardous, pressurized,
flexible connectors, and allowing great flexibility in locating
the container.
REGAL Series 2000 High Capacity Gas Chlorinators
All the features that have made the REGAL Series 200 low to
medium-capacity units the standard of the industry are
embodied in the Series 2000 High Capacity Gas Chlorinators.
• They mount directly to the valves of approved gas
manifold assemblies.
• They employ the same safe operating principle: chlorine is
drawn through the regulator and metering panel by a vacuum
created by water being forced under pressure through an
ejector nozzle. Chlorine is never under pressure in the system.
• Their simple design uses fewer parts than competitive units;
all parts are designed for maximum strength, and are made
of corrosion resistant or corrosion proof materials.
• They do not require cabinets, therefore they save space.
• They are quick and easy to service and maintain.
• They can be used in multi-point applications.
• Automatic switchover models are available.

SMARTVALVE
FOR FEEDBACK (CLOSED LOOP) CONTROL SCHEMES
Chlorinators’ new Model 7009
and Model 7010 SMARTVALVEs
are highly sophisticated control
valves for use wherever chlorine
or sulfur dioxide is needed to
treat varying water flow rates
and/or varying water quality.
These SMARTVALVEs:
• Can be configured to operate in either
of the following control schemes: flow
proportional control, residual only
control, compound loop control or
feed forward dechlorination control.
• Include a unique “linearization” program
that assures the SMARTVALVE’s digital
display reading matches the reading
indicated on the gas feed system’s
metering tube.
• Can automatically compensate for
changing system hydraulic “lag time”
that occurs as the water flow rate
increases and decreases.
• Can operate with ORP monitors or
residual analyzers.
• Include an adjustable “deviation
alarm” consisting of an LED and a
relay that alerts operators when
residual is too low or too high.
• Include a residual “deadband” adjustment
within which the controller will not
make any corrections. This is to
enhance the stability of the feedback
control scheme.
• Can be operated in the field four ways:
fully automatic, electric/manual, and
two (2) methods of manual.
• Digital display and annunciator LEDs
indicate:
– Flow process variable in actual
numbers or as a percent of flow.
– Residual process variable in PPM
residual or ORP value.
– Valve plug position in pounds per
day (PPD) of actual gas feed rate.

SMARTVALVE
THEORY OF OPERATION
Compound Loop Control
A water flow meter with a 4-20
mA signal transmitter continually
measures the amount of water
flowing and transmits instantaneous signals to the primary
input of the REGAL Model
7009 or 7010 SMARTVALVE
causing the valve to feed the
correct amount of chemical
to the water based on the
immediate dosage setting.
At the same time, a residual or
ORP analyzer draws a continuous
sample of the treated water
at the appropriate point
downstream of the chemical
injection point (after suitable
mixing is achieved) and sends
a proportional signal to the
secondary input of the REGAL
Model 7009 or 7010 SMARTVALVE based on the value of
the actual residual measured.
The controller circuitry in
the SMARTVALVE compares
the measured residual to the
desired residual (operator
established set point) and
sends a timed correction signal
to the SMARTVALVE motor
driver circuitry based on the
results of the analysis. If the
analysis shows an actual
residual greater than (or less
than) the desired residual, the
timed correction signal opens
or closes the SMARTVALVE
motor driver circuitry as
necessary in an attempt to
keep these two values the same.

REGAL SERIES 3000
GAS DETECTOR
The new REGAL Chlorine or
Sulfur Dioxide Gas Detectors
are designed for use wherever
chlorine or sulfur dioxide is
stored, distributed, or where
potential leakage would pose a
risk for personnel and property.
• Properly installed, calibrated and
maintained, the REGAL Gas
Detector senses the presence
of free chlorine or sulfur dioxide
in the environment - at levels
below those mandated by OSHA throughout the working life of
the sensor.
• 3 - digit display and 12 LED bar
graph shows the chlorine or
sulfur dioxide gas concentration.
• Audible and relay ‘warning’
alarm at 1 PPM for chlorine and
at 2 PPM for sulfur dioxide and
‘danger’ alarm at 3 PPM for chlorine
and at 5 PPM for sulfur dioxide.
• Displays and transmits sensor
or signal failures via an LED
and a designated relay.
• Maintenance-free sensor.
• Capable of transmitting digital
information for computerized
data logging.
• Bar graph LED representing
the highest (10 PPM maximum
for CL 2 and 20 PPM maximum
for SO2) detected level stays lit
until manually reset even as the
gas concentration decreases.
®
• No need to flush, purge or
recalibrate the sensor after an
exposure to chlorine or sulfur
dioxide gas.
• An “optional” Regal Serial to Analog
Converter is available to provide
a 4-20 milliamp DC output equal to
gas concentration in PPM (mg/l).
REGAL
SERIES 3000
GAS DETECTOR
THEORY OF OPERATION
A regulated voltage of 24 VDC is
provided over a two-wire shielded
cable to the sensor unit from the
detector’s main power supply.
The sensor transmitter board
converts the sensor cell output,
which is representative of the
chlorine gas concentration, to a
4-20 milliamp DC output signal
for transmission to the receiver
board. The receiver board
converts the analog current signal
to a continuous pulse train for
processing by the microcontroller.
When the unit is subjected to
the varying concentrations of
gas (up to 10 PPM for chlorine
and up to 20 PPM for sulfur
dioxide), the detector displays
the actual concentration on the
3 digit display. The respective
LED’s on the bar graph also
light. As the concentration of
gas increases, the appropriate
bar graph LED’s blink and the
audible alarm sounds when it
passes the WARNING alarm
point (1 PPM for chlorine and 2
PPM for sulfur dioxide) and the
DANGER alarm point (3PPM for
chlorine and 5 PPM for sulfur
dioxide) thresholds. The LED
representing the highest detected
level stays lit even as the
concentration decreases. The
alarms are acknowledged and
reset using the keypad. The bar
graph LED’s will continue to
blink until the gas concentration
subsides to normal levels and
the system is reset.

THEORY OF OPERATION
As previously mentioned, all REGAL SMARTVALVES are designed
to automatically regulate the gas feed rate that is necessary to
maintain the desired chemical residual. Regardless of which control
scheme the SMARTVALVE is configured for, the main factors to
determine this regulation are both the volume and quality of the
water that is being treated. Analog output (4-20 milliamp) is
transmitted to the SMARTVALVE from a water flow meter and/or a
residual analyzer to signal the valve when and how much adjustment
is required to maintain the proper residual.

GAS CHLORINATORS and SULPHONATORS
STAND-BY CHLORINATION:
The safest, most reliable, most economical systems to use when service
must not be interrupted but cannot be monitored at all times.
SAFEST
BECAUSE THEY’RE REGAL™
REGAL™ Chlorinators and Sulphonators are known
worldwide as the safest on the market.
Here’s why:
• They clamp directly onto the cylinder valve with
the strongest, most corrosion-resistant yoke in
the industry.
• In the chlorinator or sulphonator system, the gas is
never under pressure. Chlorine or sulfur dioxide is
drawn from the cylinder by a vacuum created by the
flow of water through the ejector. If any part of the
system is damaged, the gas shuts off immediately
and automatically.
• The REGAL ejector nozzle (venturi) – the component
that creates the vacuum which draws the gas from the
cylinder – is a single, precisely manufactured piece,
made of strong, corrosion-resistant plastic.
• The REGAL single-piece high pressure check valve
is made of a special, chlorine-and-sulfur-dioxideresistant material. The REGAL low pressure check
valve uses a very strong closing spring and a largearea diaphragm, to minimize friction loss or pressure
drop across the check valve area.

MOST RELIABLE
BECAUSE THEY’RE REGAL™ DOUBLED –
AND SPECIALLY DESIGNED FOR THE JOB
Unlike competitive systems that simply place two of
their standard chlorinators on two cylinders and use
a separate module to handle the switching function,
REGAL gives you chlorinators and sulphonators that
have been specifically designed for switchover service
– and do the switching over themselves.
REGAL Switchover Chlorinators and Sulphonators
have all the reliability factors that standard REGAL
units are noted for: the same simple, efficient design
and the same bigger, more corrosion-resistant vital
parts than competitive units have.
The basic difference between the standard and switchover
REGALs is that the latter have built-in corrosion-proof
and permanently adjusted switchover latches and reset
knobs* – which like everything else bearing the REGAL
name, are designed with simplicity in mind.
* Other differences are: in the switchover units, the
flowmeter/rate valve and the pressure relief valve
are separate, wall-mounted units – as they must be,
because they serve whichever chlorinator or sulphonator
is operating at the moment. Also the gas supply
indicator has been replaced with an indicator that
shows which unit is in use and which is the stand-by.
Should something happen to the operating unit, the
other is available to provide continuous operation of
the gas supply.

By contrast, the wall-mounted, vacuum/
differential-pressure regulators required
by competitive systems are relatively complex.
A failure of any component in these competitive
external regulators means a total loss of
disinfection – a serious matter.
Each unit is complete...you can be sure to have a full
supply of gas no matter what.
In normal operation, one unit supplies gas until its
cylinder approaches empty – at which point the other
unit starts opening up, keeping the gas supply steady.

MOST ECONOMICAL
BECAUSE THEY’RE REGAL™
REGAL Chlorinators and Sulphonators are the most
economical for these basic reasons:
1. They are so rugged, so reliable, and so corrosionresistant that they hardly ever need servicing.
2. If they ever do need servicing or if they are seriously
damaged or impurities ever get into them – you can
take them completely apart and reassemble them in
minutes, using only a screwdriver and a pair of pliers.
And if you need a new part, we'll send it out as soon
as you call us.
3. The switchover latching devices in the REGAL
units are permanently adjusted, unlike the separate,
external switchover units of competitive systems,
which must be adjusted frequently.

REGAL SERIES 7009/7010 SMARTVALVES
For Feedback (Closed Loop) Control Schemes
of the number of pulses generated. Shaft
direction shall be a function of phase
sequence, and speed shall be a function
of the pulse rate. The rotary motion of the
motor shall be converted to a linear
motion driving a precision machined
valve plug in an orifice via a lead screw.
GENERAL
The REGAL Series 7009/7010
SMARTVALVES™ shall be a modular
system component with built-in
microprocessor controller capable
of performing open loop and
closed loop control schemes.
The valve plug shall move linearly a
maximum of 1" for all capacities through
2000 PPD based on a maximum of sixteen
revolutions of the stepper motor with two
hundred precise motor positioning points
per revolution. The lead screw and valve
plug shall move linearly a maximum of
0.0003125" per motor pulse @ 1" travel.
The REGAL SMARTVALVE shall
offer the user a choice of four
(4) automatic control schemes;
Flow Proportional Control,
Residual (ONLY) Control, Compound
Loop Control or Feed Forward
Dechlorination Control.
These control schemes are briefly defined
as follows:
A.Flow Proportional Control (FPC)
This control scheme is needed whenever
the water flow rate to be treated varies
and will work well as long as the quality
of the water remains constant. In this
control scheme, the SMARTVALVE
automatically regulates the magnitude of
gas flow from a REGAL Gas Feed
System in direct proportion to the varying
system water flow rates. The required
ratio “dosage” of chemical to the water
flow is easily set by the operator to
maintain the desired residual using the
keypad on the SMARTVALVE enclosure.
B.Residual (ONLY) Control (rES.C)
This control scheme is used when the
system water flow rate is non-varying
but the quality (demand) of the water
varies. In this control scheme, a residual
or ORP analyzer takes a continuous
sample of the properly mixed, treated
water downstream of the chemical
injection point and sends a proportional
signal to the SMARTVALVE controller
circuitry representative of the actual
residual measured. The SMARTVALVE
compares the measured residual value
to the desired residual value and sends
a correction signal to the SMARTVALVE’s
motor driver circuitry as necessary in
an attempt to keep these two values
the same.
C.Compound Loop Control (CLC)
This control scheme is needed when
both the system water flow rate and the
quality of the water varies. In essence,
it is a combination of Flow Proportional
and Residual only Control. Flow
Proportional Control takes care of
volumetric water flow rate changes
while Residual Control automatically
compensates for changes in water quality.
D.Feed Forward Dechlorination
Control (FF.dC)
In a Feed Forward Dechlorination Control
System, a residual or ORP analyzer is
used to measure the chlorine residual
BEFORE the sulfur dioxide application
point and based on the results of the
analysis, a correction signal is generated
to furnish the required dose of sulfur
dioxide needed to reduce the chlorine
residual analyzed. In this system, the
control analyzer does not see the results
of the sulfur dioxide application.
GENERAL SPECIFICATIONS
The REGAL SMARTVALVE shall be
available in eight (8) maximum capacities:
10, 25, 50, 100, 250, 500, 1000, and 2000
PPD (200, 500, 900, 2000 and 5000
gms/hr and 10, 20, and 40 kg/hr) using
only four (4) different valve plugs.
Model 7009 – Capacities to 500 PPD
Model 7010 – Capacities of 1000 and
2000 PPD
The REGAL SMARTVALVE shall include
a four phase linear, heavy duty stepper
motor, feedback potentiometer and
modulating gas flow control valve. The
circuitry shall produce a series of pulses
such that the motor position is a function
For maximum system accuracy, and to
compensate for manufacturing tolerance
differences in the various parts making
up the complete gas feed system, the
SMARTVALVE shall include a program
by which the factory and/or the end user
can easily “linearize” the valve plug position
to precisely match the digital display and
the system metering tube reading at 25%,
50%, 75%, and 100% of the gas feed
system’s capacity.
If a mistake is made while “linearizing” the
SMARTVALVE causing settings to fall
outside acceptable values, the SMARTVALVE must contain a program whereby
the operator can easily reset “typical linear
electrical values” by simply pressing two
(2) keypad buttons at the same time.
For further overall system accuracy, and
because some systems require a faster
response than others, the SMARTVALVE
shall include a program by which the factory
and/or the end user can easily decrease
or increase the speed of response of the
stepper motor from one motor revolution
every ten (10) seconds to one motor
revolution every one (1) second.
All REGAL SMARTVALVEs shall include a
manual feed rate adjustment knob with
indicator pin and plate for use during power
outages. This feature shall give the operator
four (4) ways to operate the SMARTVALVE;
fully automatic, electric/manual and two (2)
forms of only manual control (manual via the
adjustment knob on the SMARTVALVE,
and manual via the rate adjustment valve
furnished as part of the gas feed system.)
Should an electrical surge, etc. upset
or scramble the program settings, the
operator MUST be able to reload TYPICAL
VALUES into the microprocessor by
pressing and holding one keypad button
while reapplying AC electrical power to
the SMARTVALVE.
SERIES 7009/7010 SMARTVALVE™ DIMENSIONS
If the REGAL SMARTVALVE is not
receiving an analog input signal or, if the
signal wires are reversed or, if the analog
signal is too high, the digital display shall
indicate these conditions without the need
of meters or test equipment.
The REGAL SMARTVALVE shall also
include an “averaging” parameter that can
easily be used to smooth out fluctuations
caused by the flowmeter and/or the
flowmeter transmitter.
The SMARTVALVE shall include a serial
communications output producing a digital
20 mA current loop output. This program
is accessed through the “Engineering”
menu and provides two (2) choices (Cont
or F dU.) Cont = A continuous output of
valve plug position in PPD. F dU = Full
duplex providing the user with full control of
the SMARTVALVE from a remote site.
If the serial communications interface to
field mounted devices requires analog
rather than digital inputs, the optional
REGAL Model 7600 Serial to Analog
Converter can be used to convert the
“continuous” digital output to a 4-20
milliamp analog output representing
instantaneous gas feed rate in PPD.

SMARTVALVE
™
4. “ F e e d F o r w a r d D e - C h l o r i n a t i o n ”
will require the use of two REGAL
SMARTVALVES, with the first valve
used to disinfect the water supply with
chlorine and the second valve used to
remove the chlorine residual with sulfur
dioxide before the water returns to
its natural environment. As in the
case with “Compound Loop Control,”
continuous signals will be sent to the
SMARTVALVES from both a water flow
meter and a residual analyzer. The first
point of application (chlorine) will be
located between the flow meter and the
analyzer while the second point of
application (sulfur dioxide) will be located
downstream from the residual analyzer.
GENERAL
The REGAL Series 7000 SMARTVALVE™ shall be a modular system
component capable of automatically
regulating the chemical flow rate of
a REGAL Gas Feed System. The
SMARTVALVE will operate in
response to standard analog input
signals (4-20 milliamp DC) from
field mounted transmitting devices
such as water flow meters, residual
analyzers, ORP monitors and/or
contact closures from pump circuits.
The basic REGAL SMARTVALVE
shall be available in capacities
ranging from 10 to 2000 PPD and
will be used for either “Flow
Proportional” or “Step Rate” Control
Schemes (see descriptions below).
The following models and capacities
will be available:
Model 7001 – Flow Proportional
(10 to 500 PPD)
Model 7002 – Step Rate
(10 to 500 PPD)
Model 7006 – Flow Proportional
(1000/2000 PPD)
Model 7007 – Step Rate
(1000/2000 PPD)
1. “Flow Proportional Control” should be
used whenever the water flow rate
varies but the quality of the water
remains constant. In this control
scheme, the SMARTVALVE will automatically regulated the chemical flow
rate relative to the varying water flow.
The required ratio of chemical to water
flow will be determined and set by
the operator.
2. “Step Rate Control” should be used in
applications where fixed speed pumps
(up to four) are used to move the water
to be treated from multiple water lines
into one common line. The SMARTVALVE will receive on/off signals from
the pump circuits and respond by
automatically adjusting the valve plug
position based upon which, and how
many pumps are currently running.
A more versatile, enhanced version
of the REGAL SMARTVALVE shall be
capable of operating in four different
Control Schemes (described below).
The following models and capacities
will be available:
Model 7009 – 10 to 500 PPD
Model 7010 – 1000/2000 PPD
1. “ Flow Proportional Control”. See
previous explanation.
2. “Residual Only Control” should be used
when the water flow rate remains
constant but the water quality varies. The
SMARTVALVE receives 4-20 milliamp
signals from a residual analyzer (located
downstream from the point of application)
and responds by automatically adjusting
the gas feed rate to maintain the
desired chemical residual.
3. “Compound Loop Control” is simply a
combination of both “Flow Proportional”
and “Residual Only” Control Schemes.
It should be used when both the water
flow rate and the water quality vary. In
this scheme, the SMARTVALVE will
continuously receive signals from both
a water flow meter (located upstream
from the point of application) and a
residual analyzer (located downstream).
The SMARTVALVE will respond by
automatically adjusting the gas feed
rate according to both signals to
maintain the desired chemical residual.
SPECIFICATIONS
The REGAL SMARTVALVE shall be
available in a total of eight (8) maximum
capacities:10, 25, 50, 100, 250, 500, 1000
and 2000 PPD with relative metric
equivalents of 200, 500, 900, 2000, 5000
gms/hr and 10, 20, 40 kg/hr.
a four phase linear, heavy duty stepper
motor, feedback potentiometer and
modulating gas flow control valve. The
circuitry will produce a series of pulses
such that the motor position is a function
of the number of pulses generated. The
shaft direction will be a function of phase
sequence while the speed will be a function
of pulse ratio. The rotary motion of the
motor will be converted into the linear
motion required to drive the valve plug.
The valve plug shall move a total distance
of one inch (1") for all capacities based on
a maximum of sixteen revolutions of the
stepper motor. Each motor pulse will
move the lead screw and valve plug
linearly a maximum of 0.0003125 inches.
The SMARTVALVE shall include a
program by which the factory and/or the
end user can “linearize” the valve’s digital
display to precisely match the gas feed
system’s metering tube reading.
The SMARTVALVE shall also include a
program by which the factory and/or end user
can easily increase or decrease the speed
of response of the stepper motor from one
half (0.5) to ten (10) seconds per revolution.
SERIES 7000 SMARTVALVE™ DIMENSIONS
An averaging parameter in the “configuration
mode” will prevent motor “chatter” by
allowing for slight signal fluctuations
transmitted from the flow meter and/or
residual analyzer.
The SMARTVALVE shall provide a total
of four (4) means of operation:
1. Fully Automatic.
2. Electric/Manual via an adjustment knob
used to change the gas feed rates as
shown on the PLED screen.
3. Manual via the adjustment knob which
drives the lead screw of the valve plug.
A pin attached to the lead screw will
indicate the gas feed rate adjustment.
4. Manual via the remote rate valve
assembly.
Operator interface in all three program
modes (Engineering, Configuration and
Operational) shall be via a four-button,
integrated keypad that is used to access
information which will be displayed alphanumerically on a two line LED screen. The
top line will be used to show information
regarding the following conditions:
1- Water flow rate in actual volume or
as a percentage
2- Current dosage setting
3- Valve plug position in PPD
4- Operational mode (automatic or manual)
5- Alarm conditions

FEATURES
The REGAL Model 210 incorporates the
very best available materials with the latest
technology in design and construction, to
reduce maintenance, simplify construction
and improve operation.
APPLICATION
The Model 210 is designed to handle the
vast majority of water treatment requirements.
CAPACITIES
Dual scale metering tubes with maximum
capacities of 4, 10, 25, 50 and 100 pounds
per 24 hrs. of chlorine gas with corresponding metric scales of 75, 200, 500, 900 and
2000 grams per hr. Minimum feed rate is
1/20th of maximum.
FLOW RATE ADJUSTMENT
Manually adjustable by means of a flow
rate control valve located at the top of the
flow meter. Flow rate is then regulated by a
special spring-opposed diaphragm operated valve. The system is automatic. It will go
off and on as the ejector water is turned off
and on and will always return to the pre-set
flow rate.

EJECTOR REQUIREMENTS
SPECIFICATIONS
The standard ejector is designed to withstand
static back pressures in excess of 200 psig
(14.1 kg/cm2). However, due to the potential
for "water hammer" in high pressure on-off
systems and special booster pump considerations, it is recommended that a factory
representative, or Chlorinators Incorporated
be consulted regarding installation details on
systems over 100 psig (7 kg/cm2).
The amount of water required to operate the
ejector depends upon the chlorine feed
rate, water back pressure and water supply
pressure available. Generally, the higher the
chlorine flow and higher back pressure the
greater the water flow is needed.
The chlorinator shall be a REGAL Model 210
manufactured by Chlorinators Incorporated,
Stuart, Florida, with a maximum capacity of
100 lbs./24 hrs (2000 gms/hr). It will be a
vacuum operated solution feed type and
mount directly on the chlorine cylinder valve
by means of a positive yoke type clamp
having an integral tightening screw with
slide-bar handle.
All regulating, metering, flow adjusting and
safety functions shall be incorporated in the
cylinder mounted unit.
The inlet safety shut-off/vacuum regulating
valve shall be of capsulated construction,
easily removable as a unit from the outlet
side of the yoke for ease of inspection,
cleaning or maintenance.
Vacuum shall be created by an ejector
assembly connected directly to the chlorine
solution diffuser. The assembly shall consist
of a single piece venturi-recovery throat to
prevent mis-alignment; also, a back flow
check valve to prevent water from entering
the gas system. The check valve shall be
of positive, tight shut-off, unitized design
not requiring springs or diaphragms for
tight closing.
OPERATION
The chlorinator is clamped on the chlorine
cylinder valve. The ejector assembly is normally attached to the solution diffuser at the
point of injection (it may be wall mounted,
but this is not recommended). A vacuum line
connects these two units.
Water, under pressure is forced through the
ejector nozzle which creates a strong vacuum
in the ejector body. This pulls gas into the
ejector through a special back-flow check
valve and then into the nozzle outlet. The
gas mixes with the ejector water and is
discharged through the diffuser into the
water being treated.
The ejector vacuum is transmitted back to the
chlorinator through the vacuum line; then
through the rate valve and the flow meter and
to the back of the diaphragm. With sufficient
vacuum, the diaphragm moves backward,
opening the spring loaded inlet regulating valve
to allow chlorine to enter from the cylinder.
The chlorine passes through the flow rate
indicating meter, flow rate adjusting valve
and to the ejector.
SERVICE
Most service problems can be handled by
the user, with no special tools. If that is not
possible, or desirable, the chlorinator and
ejector assembly can be shipped to the
factory for overhaul and retest to like-new
condition for a reasonable single service
charge. If the unit cannot be taken out of
service, we will send an “exchange” unit.
The REGAL Model 216 Automatic
Switchover Gas Chlorinator is a totally
vacuum-operated system which is
designed to automatically switch the
chlorine feed from an empty cylinder to a
full cylinder. It is also designed to provide
system-backup. Should a problem develop
with either vacuum regulator, chlorination
can be continued. The chlorinators are of
the vacuum-operated solution-feed type,
designed for mounting directly on a chlorine
cylinder valve. The switchovers are selfactuating, eliminating the need for a separate
switchover module. A separate gas flow
meter and rate control valve panel may be
located wherever it is most convenient for
the operator and connected between the
vacuum regulator junction at the pressure
relief (vent) valve, and the ejector, by means
of safe vacuum tubing. The ejector assembly
contains a back flow check valve. Chlorine
gas flow rate is regulated by a springopposed diaphragm regulator which is also
the automatic safety shut-off valve. Should
vacuum be interrupted for any reason
anywhere in the system the safety shutoff/inlet valve immediately closes, shutting
off the chlorine supply from the cylinder. A
pressure relief valve designed to “vent”
the system also provides a central
interconnection point for the vacuum tubing.
OTHER IMPORTANT FEATURES
• System Back-up — Each cylinder’s chlorinator
has its own vacuum regulating diaphragm and
safety/inlet valve insuring that chlorination can
be continued if service should be required on
either chlorinator.
• Corrosion-resistant, Factory-adjusted Detent
Mechanism — Detent does not require any
field adjustment assuring that cylinder
switchover will occur at the proper time, and
that all available gas in supply cylinder will
be used.
• In-Use/Stand-by Indication — Prominent
indicator on face quickly tells which is the
stand-by cylinder and which cylinder is in
use. Optional flowmeter panels are available
for applications where the feed rate must be
known at the chlorinator and the flow
meter/rate valve panel cannot be seen.
CAPACITIES

OPERATION
The chlorinators are clamped onto the chlorine
cylinder valves. The ejector assembly is
normally attached to the solution diffuser at
the point of injection. A vacuum line is
connected from each cylinder unit to the wallmounted, pressure-relief (vent) valve, and a
single vacuum line connects the outlet of the
connector to a wall-mounted, flow-meter/rate
valve panel. The ejector is connected to the
rate valve panel with a single vacuum line.
Water, under pressure, is forced through the
valve and then into the nozzle outlet. The gas
mixes with the ejector water and is discharged
through the diffuser into the water being treated. The ejector vacuum is transmitted through
the vacuum line to the rate valve and the flow
meter; then through the connector on the
pressure-relief (vent) valve and on to the back
of the operating chlorinator diaphragm. With
sufficient vacuum, the diaphragm moves
backward, opening the spring-loaded inlet regulating valve to allow chlorine to enter from the
cylinder. The chlorine passes through the
chlorinator, the pressure-relief (vent) valve
connector and the flow rate indicating
meter/flow rate adjusting valve to the ejector.
When the operating cylinder starts to run out,
the vacuum starts to build up in the system
causing the diaphragm of the chlorinator on
“stand-by” to be drawn back, overcoming a
detent mechanism and opening the
safety/inlet valve. This allows chlorine gas to
be withdrawn from the “stand-by” cylinder to
satisfy the increased system vacuum and the
vacuum falls back to the operating level.
The original supply cylinder also continues to
feed until it is empty, virtually assuring that
there will be no interruption of chlorination
and that full use will be made of all available
chlorine. This also reduces the possibility and
risk of returning cylinders with some remaining gas to the supplier.
SPECIFICATIONS
The chlorinator system shall be a vacuumoperated, solution-feed type and shall automatically switch the chlorine supply from an
empty cylinder to a full cylinder. It shall be
REGAL Model 216 manufactured by
Chlorinators Incorporated, Stuart, Florida, and
shall have a maximum capacity of 100 lbs./24
hrs (2000 gms/hr).
The Model 216 Vacuum-Operated Automatic
Switchover Chlorinator shall consist of the
following components: Two (2) automatic
switchover vacuum regulators for mounting
directly on chlorine gas cylinder valves, one
(1) pressure-relief (vent) valve, one (1)
chlorine gas flow meter panel with rate valve,
& one (1) ejector/check valve assembly.
The vacuum regulators shall mount directly
onto the cylinder valve by means of a positive
yoke type clamp having an integral tightening
screw with slide bar handle. The main vacuumregulating diaphragm of each chlorinator shall
have a minimum operating area of 13 sq. inches
in order to achieve required accuracy and
repeatability of the set chlorine flow rate. All
metallic bolts shall mate with metallic threaded
nuts or inserts. Plastic mating threads for
metallic bolts shall not be acceptable.
Each chlorinator vacuum regulator shall have
its own diaphragm, safety-shutoff/inlet valve
and switchover detent mechanism, thereby,
allowing chlorination to continue should it
become necessary to remove either vacuum
regulator from service for cleaning or servicing.
Switchover detent mechanism shall be made
of corrosion-resistant materials and shall not
require any field adjustment.

and inlet spring against corrosion.
4. Combined O-ring/diaphragm sealing of the front
and back body parts helps prevent air leaks into
the system and eliminates the need for special
tightening tools.
5. Inlet safety valve "capsule" allows easy removal
with minimal disassembly for inspection or
cleaning with no special tools.
APPLICATION
The Model 2101 Gas Chlorinators are designed to
handle the vast majority of chlorine treatment
requirements of medium to large water and wastewater treatment systems. Municipal water and sewer
sysems are as easily treated as industrial systems.
Most cooling water and process water applications
can be handled by these chlorinators. Model 2101 is
also ideal for "shock" treatment systems.
CAPACITIES
Dual scale metering tubes with maximum capacities
of 1000 and 2000 pounds per 24 hours of chlorine
gas with corresponding metric scales of 20 and 40
kilograms per hour. The minimum feed rate is
1/20th of maximum for each metering tube. The
flow metering tubes are interchangeable and may
be changed in the field.
Manual adjustment is by means of a flow rate control
valve located at the top of the flow meter/rate valve
Model 2101 Gas Chlorinators are tested to give
the best operation in the system being treated.
Ejector assembly is chosen for, and tested to, the
individual user's conditions. Generally, the amount
of water (GPM) required to operate the ejector
depends upon the chlorine flow rate, the ejector
back pressure, and the water supply pressure
which is available. In all cases, the minimum
pressure differential and water flow for your
installation should be determined prior to installation
and start up. Refer to Application Bulletin 1009.
OPERATION
The vacuum regulator is clamped on the header
valve of a chlorine cylinder or ton container
manifold. It may also be clamped directly on to a
chlorine ton container valve, using a TAY-200
adaptor, if used for intermittent or "shock" treatment
for short periods of time (consult Chlorinators
Incorporated). The ejector assembly is either wall
mounted or supported by rigid pipe. A chlorine
flow meter/rate valve panel is located between
these two units and a vacuum lineconnects the
three components.

The REGAL Model 2107 Automatic Switchover Gas
Chlorinators are totally vacuum-operated chlorination systems which are designed to automatically
switch the chlorine feed from an empty chlorine
source to a full chlorine source. It is also designed
to provide system-backup. Should a problem develop
with either vacuum regulator, chlorination can be
continued. Chlorinators are of the vacuum operated
solution feed type, designed for mounting directly
on a chlorine manifold header valve or on a TAY-200
ton container adaptor. The switchover chlorinators
are self-actuating, eliminating the need for a
separate switchover module. A separate chlorine
gas flowmeter and rate control valve panel may be
located wherever it is most convenient for the
operator and connected between the vacuum
regulator junction at the pressure relief (vent) valve,
and the ejector, by means of safe vacuum piping.
The ejector assembly contains a back flow check
valve. Chlorine gas flow rate is regulated by a
spring-opposed diaphragm regulator which is also
the automatic safety shut-off valve. Should vacuum
be interrupted for any reason anywhere in the
system the safety shut-off/inlet valve immediately
closes, shutting off the chlorine supply from the
pressurized chlorine source. A pressure relief valve
designed to “vent” the system also provides a
central interconnection point for the vacuum piping.
FEATURES
The REGAL Model 2107 incorporates the very best
available materials with the latest technology in
design and construction. It includes design and materials improvements that are not available on other
chlorinators, and will reduce maintenance, simplify
assembly and improve operation.
1. Materials that stand up to ultraviolet degradation and
chlorine attack… wet or dry.
2. Limited warranty for the life of the chlorinator
on three vital parts… diaphragm, inlet adaptor and
inlet spring against corrosion.
3. Combined O-ring/diaphragm sealing of the front
and back body parts helps prevent air leaks into the
system and eliminates the need for special tightening tools.
4. Inlet safety valve "capsule" allows easy removal with
minimal disassembly for inspection or cleaning, with
no special tools.
5. Fewer parts, simpler design for less down-time,
easier maintenance and lower costs, year after year.
1. System backup — Each cylinder’s chlorinator has its
own vacuum regulating diaphragm and safety/inlet
valve insuring that chlorination can be continued if
service should be required on either chlorinator.
2. Corrosion-resistant, Factory-adjusted detent mechanism — Detent does not require any field adjustment assuring that switchover will occur at the
proper time, and that all available gas in the supply
source will be used. Corrosion resistant materials in
detent stand up to wet, dry and liquid chlorine.
3. In-use/stand-by indication — Prominent indicator on
face quickly tells which is the stand-by cylinder and
which cylinder is in use. Optional flow meter panels
are available for applications where the feed rate
must be known at the chlorinator and the flow
4. Pre-tested/Pre-set — The entire REGAL 2107 Gas
Chlorinator is tested as a system at the factory and
no field adjustment or calibration is required to place
it into operation.
APPLICATION
The Model 2107 Gas Chlorinators are designed to
handle the vast majority of chlorine treatment requirements of medium to large water and wastewater
treatment systems. Municipal water and sewer systems
are as easily treated as industrial systems. Most cooling
water and process water applications can be handled by
these chlorinators. Model 2107 is also ideal for "shock"
treatment systems.

CAPACITIES
Dual scale metering tubes with maximum capacities

gas with corresponding metric scales of 20 and 40
kilograms per hour. The minimum feed rate is 1/20th
of the maximum for each metering tube. The flow
metering tubes are interchangeable and may be
changed in the field.
Manual adjustment is by means of a flow rate control
valve located at the top of the flow meter/rate valve
panel. Flow rate is then regulated by a special springloaded, diaphragm-operated valve in the vacuum
regulator. The system is automatic. It will turn off and
on as the ejector water supply is turned off and on and
will always return to the preset flow rate.
Model 2107 Gas Chlorinators are tested to give the
best operation in the system being treated. Ejector
assembly is chosen for, and tested to, the individual
user's conditions. Generally, the amount of water
(GPM) required to operate the ejector depends upon
the chlorine flow rate, the ejector back pressure, and
the ejector water supply pressure which is available.
In all cases, the minimum pressure differential and
water flow for your installation should be determined
prior to installation and start up. Refer to Application
Bulletin 1009.
OPERATION
The vacuum regulator is clamped on the header
valves of chlorine cylinder or ton container manifolds.
It may also be clamped directly on to chlorine ton
container valves, using TAY-200 adaptors, if used for
intermittent or "shock" treatment for short periods of
time (consult Chlorinators Incorporated). The vacuum
line is connected from each vacuum regulator unit to
the wall mounted, pressure relief (vent) valve, and a
single vacuum line connects the outlet of the pressure
relief valve to a wall mounted, flow meter/rate valve
panel. The ejector assembly is either wall mounted or
supported by rigid pipe, and is connected to the flow
meter/rate valve panel with a single vacuum line.
Water, under pressure is forced through the ejector
nozzle which creates a strong vacuum in the ejector
body. This pulls gas into the ejector through a special
back-flow check valve and then into the nozzle outlet.
The gas mixes with the ejector water and is
discharged through the solution piping into the water
being treated.
The ejector vacuum is transmitted through the vacuum
line to the rate valve and the flow meter; then through
the connector on the pressure relief (vent) valve and on
to the back of the operating chlorinator diaphragm. With
sufficient vacuum, the diaphragm moves backward,
opening the spring loaded inlet regulating valve to allow
chlorine to enter from the chlorine source.The chlorine
passes through the chlorinator and the flow rate indicating meter/flow rate adjusting valve to the ejector.
When the operating chlorine source starts to run out,
the vacuum starts to build up in the system causing
the diaphragm of the chlorinator on "stand by" to be
drawn back, overcoming a detent mechanism and
opening the safety/inlet valve. This allows chlorine gas
to be withdrawn from the "stand by" chlorine source to
satisfy the increased system vacuum and the vacuum
falls back to the operating level. The original chlorine
supply also continues to feed until it is empty, virtually
assuring that there will be no interruption of chlorination
and that full use will be made of all available chlorine.
This also reduces the possibility and risk of returning
containers with some remaining gas to the supplier.

GENERAL
The REGAL Series 3000 Gas
Detector shall use microprocessor
based electronics and shall be
capable of accurately sensing
and displaying the presence of
free chlorine or free sulfur dioxide
in the environment at levels below
those mandated by OSHA
throughout the working life of the
sensor(s) used. The gas detector
monitor enclosure shall be NEMA
4X. The sensor enclosure(s) shall
be watertight, UL approved, and
RFI/EMI protected.
The single sensor gas detector shall
include a single, isolated and unpowered
4-20 mA analog output circuit board;
whereas the dual sensor unit shall
include a dual, isolated and unpowered
4-20 mA circuit board. All REGAL Series
3000 Gas Detectors shall include six
relay circuits.
2 WARNING relays
2 DANGER relays
1 HORN/FAILURE relay
1 LATCH relay
The monitor shall continuously scan and
display the sensor data using a multicolor bargraph indicator for each sensor
to present both the current and un-reset
peak gas concentrations. A three digit
numeric display shall display the current
gas concentration. For the dual sensor
version, the numeric display shall present
the two sensor outputs alternately at
about 5 second intervals. An arrowhead
LED indicator under each bargraph is
used to indicate which sensor information
is being presented numerically. A
separate LED indicator shall show the
gas each sensor is set up to monitor as
it is presented.
Dual sensor detectors can monitor one
of the aforementioned gases at two
different locations or, they can be
configured to monitor both chlorine and
sulfur dioxide.
The two WARNING relays, the LATCH
relay and the HORN/FAILURE relay are
SPDT. The two DANGER relays are
DPDT. All relays are rated at 10 amps @
250 VAC and 50 or 60 Hz.
The WARNING relays activate at 1 PPM
for chlorine and at 2 PPM for sulfur
dioxide. The DANGER relays activate at
3 PPM for chlorine and at 5 PPM for
sulfur dioxide. On a single sensor unit,
both WARNING relays and both DANGER
relays activate during an appropriate
alarm event. On a dual sensor unit, one
WARNING relay and one DANGER
relay is dedicated to each sensor.
When the sensor is subjected to varying
concentrations of gas, the monitor
displays the actual concentration on the
appropriate bargraph and the numeric
display. As the concentration of gas
increases, the internal alarm horn shall
sound and the appropriate WARNING
relays, HORN/FAILURE relay and
LATCH relay (if latch time is set to 0)
shall engage when passing the
WARNING point. If the concentration of
gas increases to the danger point, the
internal horn and HORN/FAILURE relay
will be reasserted if they had been
silenced (turned OFF) and, the appropriate DANGER relays shall latch into
the alarm state. The bargraph LED
representing the highest detected level
MUST stay lit even if the gas concentration
decreases to let the user know they has
a leak and, the magnitude of the leak
even if it had cleared itself. The internal
alarm horn and the HORN/FAILURE
relay can be configured in the field via an
electronic DIP switch in the monitor to
"pulse" or be "on continuously" when
activated by an alarm event. The horn
and external alarm devices connected to
the HORN/FAILURE relay can be
silenced (turned off) by pressing the
SILENCE keypad button. A RESET
keypad button shall be provided to
acknowledge and reset alarms once the
problem has been corrected and the
indications return to 0 PPM.
The detector shall include a program to
allow the user to easily test the condition
of sensors and disable all alarm circuits
for a timed 15-minute interval using the
keypad. The user must also be able to
perform a relay test, which will individually
and sequentially activate, then deactivate
the six relay circuits.
Loss of signal from the sensor(s) results
in a "Fail" message on the numeric
display and a relay closure of the
HORN/FAILURE relay. An off scale
message "OFS" is also presented on
the numeric display for full scale readings
in excess of 10 PPM chlorine or 20 PPM
sulfur dioxide.
When the REGAL Series 3000 Gas
Detector includes the OPTIONAL
battery back-up module, and during
primary power failures, all display illumination shall automatically be turned off
to conserve battery power except for the
BATTERY LED to let the user know the
system is still functioning. All detection,
alarm and relay functions continue to
operate normally. If during the power
outage, the user wishes to observe
conditions on the bargraphs and the
numeric display, he can turn on the
displays for one sensor scan cycle by
pressing any keypad button. The display
then automatically turns off again to
continue conserving battery power.
The REGAL Series 3000 Gas Detector
shall include a program to simplify
calibrating the gas detector by using the
keypad buttons. There shall be no need
to go inside the enclosure for calibration.
The calibration program shall automatically disable all alarm relay operations
during the calibration process. If the
operator does not wish to calibrate the
detector but simply wants to check
sensor condition by applying the
appropriate gas to the sensor inlet, the
detector MUST include a separate
program by which the operator can use
the keypad to disable all alarm circuits
for a timed fifteen minute period while
performing this test, then automatically
again enable alarms.
If a mistake is made during the calibration
process, the user MUST be able to reset
the detector back to factory specifications
by pressing one keypad button.

Comparative safety of Chlorine, Calcium Hypochlorite and Sodium Hypochlorite
INTRODUCTION: With the greatly increased use of chlorine and chlorine compounds, there appears to be at the
same time less and less understanding and concern about safe handling, storage and use. Great respect, and often
times fear, is sill the general attitude in regards to chlorine gas. Calcium hypochlorite and sodium hypochlorite are
treated quite lightly in regards to care and safety when, in fact, they have moved far ahead of chlorine gas in the direct
or indirect cause of death, injury and property damage.
A good example of the lack of understanding is the fact that so many health and engineering organizations insist upon
chlorine gas cylinders and equipment being located in a separate, well-ventilated room – while hypochlorination
supplies and equipment are allowed to be placed in any convenient location. For greatest safety, all-chlorine and
chlorine compounds should be placed in separate, well-ventilated rooms, as well as the feeding equipment. In the
case of hypochlorites, even extra precaution should be taken.
GENERAL: Chlorine is an element and, when supplied in its basic form, is a liquefied gas under pressure. Chlorine
in pressurized containers is in the form of both liquid and gas. The element chlorine is often times combined with
other compounds to make it easier to package and handle, and to be able to use other types of feeding equipment than
required with gas chlorine. The most common powder form (and tablet form) is calcium hypochlorite. The liquid
preparation is sodium hypochlorite, which is available in various strengths and is known as bleach of laundry bleach.
Chlorine gas, itself, is primarily a respiratory irritant depending upon the concentration in the atmosphere, as well as
the duration of the exposure, it can be only mildly irritating or, in extreme cases, can even cause death. Chlorine gas
is not just obtained from a gas cylinder, but is also given off from calcium hypochlorite and sodium hypochlorite.
This means that regardless of the form in which chlorine is obtained, the fumes themselves are equally dangerous.
The United States Bureau of Mines indicated that most people cannot detect chlorine in the atmosphere at a
concentration of less than about 3.5 pounds of chlorine per million pounds of air (PPM). However, they further state
that at only 5 PPM the mixture is noxious and impossible to breathe for more than several minutes. At slightly higher
values than this, you run into irritation, coughing and truly hazardous conditions. You can readily see from these
values that anytime you can smell chlorine, you are in a hazardous atmosphere and should not remain.
Chlorine gas, itself, is neither explosive nor flammable. It is, however, a very strong oxidizing agent and will react
with almost all elements and with many inorganic or organic compounds. In doing so, the reaction usually gives off
heat. With chlorine gas obtained from cylinders, there is very little fire hazard. On the other hand, calcium and
sodium hypochlorite appear to be non-hazardous, but often react violently when in contact with many ordinary
materials – and/or with heat, spark or flame present.
Moist chlorine is very highly corrosive as a result of the formation of hydrochloric and hypochlorous acids, and
neither equipment nor supplies – in any form – should be located so that chlorine will come in contact with electrical
equipment or other equipment that will be damaged by corrosion.
LIQUID CHLORINE (CHLORINE GAS): Pure chlorine is shipped in steel containers in which the chlorine is both
in the liquid and gas phase. Since the chlorine has been thoroughly cleaned and dried before being placed in the
containers, it is non-corrosive to the steel. The chlorine cylinder valves are of a very heavy construction and are
additionally protected during handling by a heavy steel hood. Since chlorine in the cylinders is under pressure, and
the pressure increases with temperature, the cylinders are further protected from bursting by a fusible plug which is
designed to melt at between 158°F and 165°F. In the case of fire, this plug would melt allowing the chlorine gas to
escape, rather than allowing pressure to build up, which might eventually rupture the cylinder and cause pieces of
metal to be thrown out. Here, basically, are the more common safety rules for handling and storage:
(1)
When moving cylinders, the valve protection hood should be in place at all times.
(2)
Cylinders must not be dropped or struck with any force.
(3)
A safety chain or strap should be placed around the cylinder and affixed to a wall, pipe, etc. to
prevent tipping over in the event the cylinder is accidentally hit or pushed.
(4)
Cylinders should be stored in an upright position.
(5)
Cylinders should not be stored near a ventilating system, passageways, or below ground in
unventilated rooms.
(6)
Grease or oil should never be on, or around, chlorine fittings or connections.
(7)
If there is any indication of the presence of chlorine in the air, immediate action should be
taken to correct the condition. Chlorine leaks that are left alone will always get worse.
(8)
If an extensive chlorine leak is found, all persons should be kept away from the area –
preferably up-wind and at a higher level.
CALCIUM HYPOCHLORITE: Calcium hypochlorite is most usually supplied as a powder or in small granular
form, although in some cases it is compressed into tablets. In these forms, it can more easily be packaged in small
quantities, can more easily be transported, and is relatively simple to handle if very careful precautions are taken.
Contrary to popular belief, this “safe” form of chlorine causes a great number of accidents of all types. The innocence
of appearance and packaging can be very misleading. Although chlorine is purchased in this form ‘supposedly’ for
ease of handling and safety, the opposite is often true and the cost of the compound itself is at least three or four times
as much per pound of chlorine as compared to chlorine purchased in the pure form.
Some health agencies, engineers, and many users often feel that this form of chlorine supply is safe and simple to
handle, but in truth it is far more hazardous than chlorine gas due to lack of understanding and suitable precautions.
Examine closely the care and handling rules which are summarized from the basic information put out by the
manufacturers:
(1)
Never mix calcium hypochlorite with anything but water.
(2)
Store in a cool, clean, dry area in the original container and always keep covered. (Most safe
containers have a plastic bag liner which should not be removed and which should also be
carefully closed and sealed.)
(3)
The storage area should be clean and removed from any combustible material and should not be
located where chlorine fumes will cause corrosion to equipment.
(4)
Metal drums should be kept upright and should not be dropped, rolled or skidded.
(5)
When measuring calcium hypochlorite, you should use only a plastic, glass or enameled
measuring device that is completely clean, dry and free of all foreign matter.
(6)
Calcium hypochlorite, as a strong oxidizing agent, must not be brought into contact with heat,
acids or any combustible materials. These materials include paper, rags, beverages, tobacco,
oil base products, etc. Matches, fire, lighted cigarettes and any form of heat must be kept
away.
(7)
Whenever handling calcium hypochlorite, the hands must be clean and dry, and gloves should
never be worn. Hands should be washed after handling.
(8)
Never permit calcium hypochlorite to contact the eyes. Any spilled calcium hypochlorite should
immediately be flushed thoroughly with water.
(9)
Always rinse empty containers thoroughly with water.
Small oversight in adhering strictly to the rules of safe handling of calcium chlorite can prove disastrous. There have
been several occurrences where a new, sealed container dropped while unloading has caused explosion and fire which
destroyed property and put many people, severely burned, in the hospital. Almost instantaneous explosion has
occurred due to oily rags, banana peels, etc. being thrown into open containers of calcium hypochlorite. The reaction
of a lit cigarette near or thrown into, a partially filled container can be quite violent. An oily rag, wad of paper or
other combustible can be equally as serious. Motels have burned down, storehouses completely destroyed, and many
people seriously injured from careless handling and storage of this material. Unfortunately, many accidents have
occurred for unexplained reasons while operators were simply dipping a supply from the container or carrying a
supply in the same manner that they had hundreds of times before – but suddenly there was a violent explosion.
SODIUM HYPOCHLORITE: Sodium hypochlorite is a liquid supplied in various strengths of available chlorine.
Again, we are interested only in the amount of chlorine required and in ease of handling. Common household laundry
bleach is 5.25% available chlorine by weight. Solutions of approximately two and three times this concentration are
available. In this form, the chlorine solution is generally supplied in glass or plastic containers and is relatively east to
handle, although the cost as compared to pure chlorine is there to ten times as much depending upon the source and
the concentration.
Since sodium hypochlorite is a liquid, the hazards of fire and chlorine fumes are often underestimated and the same
basic rules of safety as given above for calcium hypochlorite should be followed. Many accidents and deaths have
occurred with even the relatively weak household bleach, but individual instances are not highly publicized and the
hazard often overlooked. Here are some of the basic rules in addition to those listed above:
(1)
Store in a cool, dark area away from possible falling objects or physical damage.
(2)
Avoid contact of sodium hypochlorite with the eyes or with the skin.
(3)
Keep container tightly closed and keep away from combustible materials.
(4)
If spilled, wash down thoroughly and do not allow to remain in contact with cloth, paper,
oil products or other combustible matter.
(5)
Keep containers away from heat and fire.
(6)
Never use in conjunction with acids, vinegar, toilet bowl cleaners or any other cleaning agents.
The use of sodium hypochlorite as a bleaching and cleaning agent – such as in the home – has caused several deaths
when used along with other agents which released chlorine fumes. Fires have occurred where rags and other
combustible materials soaked with sodium hypochlorite have been allowed to stand and/or where a heat source may
have been present.
CONCLUSION: Chlorine as a gas has been feared and/or treated with respect primarily due to its use during World
War I as a poison gas. No one doubts its toxicity or its potential hazard and, therefore, it is usually treated with
respect. Most people do not know the true facts about chlorine and its compounds and therefore grossly overestimate
the hazards of liquid chlorine (chlorine gas) and oversimplify the hazards connected with its compounds such as
calcium and sodium hypochlorite.
Government reports on the many tens of thousands of gas cases during World War I are remembered, but it is
overlooked that only about two thousand cases were from chlorine gas and that only seven deaths occurred. Since
chlorine remains as an everyday word, it is forgotten that mustard gas, phosgene and other gases were actually the
problem. In addition, newspapers, magazines and other reporting media tend toward sensationalism which makes
accidents involving a large number of people nationally important. Individual accidents have only local importance.
In several years there have been chlorine gas leaks in public locations where dozens or more than a hundred people
have been involved, and this received national publicity. Follow-up of these incidents was not as publicized and
where chlorine gas was involved you find very little news – since recoveries were complete, quick and injuries
comparatively negligible.
Large fires, serious burnings and extensive damage caused by calcium or sodium hypochlorite are usually reported
locally and do not receive much more publicity than a local car accident. They do not involve a large number of
people. Unfortunately, the reporting sill refers to chlorine or chemicals rather than specifically to the form of
compound that was involved.
Local reports told the following: “A large fire completely destroyed a motel in southern California” – “Three men
were very seriously burned when unloading powdered chlorine in Toledo” – “a swimming pool distributor’s ware
house was destroyed by a fire in Texas” – “a bath house and filter room in St. Louis were destroyed by fire with injury
to several when powdered chlorine ignited” – “two deaths in Illinois of housewives attributed to household bleach
used in conjunction with other cleaning fluids.” These are only a few of the many accident cases that occur every
year when using calcium or sodium hypochlorite with disregard for their hazard.
Statistically and actually, chlorine gas is the least hazardous and safest form of chlorine available today, while at the
same time being the most economical. Antiquated regulations and general dissatisfaction with chlorine gas were
based primarily upon very high-priced equipment, extremely expensive maintenance and complication of operation.
Modern technology and improved materials have eliminated these drawbacks, but lack of education in regards to
safety and modern equipment has condoned practices that are well behind the times.

POULTRY & LIVESTOCK DRINKING WATER
HOW TO ASSURE A CORRECT FREE CHLORINE RESIDUAL EXISTS AT ALL TIMES.
In order to always have a properly chlorinated water supply, chlorine needs to be injected and thoroughly mixed into a
moving body of water, which is why chlorination occurs only when the well pump or pumps are on and running. The
moving water then becomes the vehicle that takes the chlorine throughout the distribution system. When you first add
chlorine to the water, some of the chlorine is quickly consumed in satisfying the chlorine demand. Enough chlorine must be
added to assure an excess exists after the demand is satisfies and remains in the water at all times as free chlorine residual.
The free chlorine residual remaining assures that the water is properly disinfected throughout the entire drinking water line
and that no infiltration, stagnation, or recontamination has occurred.
To assure your poultry and livestock drinking water is properly disinfected at all times, the water MUST be periodically
tested to assure that a free chlorine residual exists. For example, many poultry growers have reported benefits with free
chlorine residual levels between 1.0 PPM and 5.0 PPM. This can sometimes be a difficult task due to the fact that each
drinker line is dead-ended. Water is removed from these lines only when the animals are drinking. To further compound the
issue, water is removed from many intermediate drinker locations along the individual lines and not necessarily at the ends of
each line. The water can be trapped and become stagnant as the free chlorine residual is consumed. To prevent this
condition, the end of each line should have a sampling/flush valve.
To periodically test the water, a good-quality chorine residual test kit with fresh reagents is needed. These kits are easy to
use following the instructions provided and are generally capable of testing for free as well as total chlorine residuals. Free
chlorine residual is needed since it provides quicker bacterial kill using minimal amounts of chlorine.
Chlorine residual tests should always be taken at the furthest end of each drinker line. To perform a residual test;
1. Slowly open the sampling/flush valve at the end of the line to be tested.
2. Following the instructions provided with the chlorine residual test kit, rinse the sample water vial provided with the test
kit a few times with the water to be sampled, then fill the vial with the proper volume of sample water.
3. Add the appropriate quantity of free chlorine residual reagent to the sample water again following the instructions
provided with the test kit.
4. Determine the free chlorine residual level existing in the sample water.
If the free chlorine measured is less than 1.0 PPM and no one has changed the chlorine gas feed rate to cause this condition;
5. Open the sampling/flush valve fully, allowing the water to be flushed outside to an appropriate drain location. The
flushing should continue long enough so that the well pump and chlorinator turn on in order to bring a freshly chlorinated
supply of water into the line while the water is draining.
6. After an appropriate drain time interval, close the sampling/flues valve then repeat steps #1 through #4 above until the
desired free chlorine residual is obtained. Adjust the chlorinator gas feed rate if necessary to obtain the correct reading.
7. Proceed to the next drinker line and repeat this procedure. Continue until all lines have been tested.
Residual testing of the drinking water should be done at least once per day for each drinker line.

CHLORINE VACUUM LINES VERSUS SOLUTION LINES
(Chlorine Solubility in Water)
Even though the concept of the direct – cylinder – mounted gas chlorinator utilized with a remote ejector,
close coupled to the application point, has over forty to forty-five years of proven history, there still exists a
great deal of confusion and misinformation regarding desirability of avoiding chlorine solution lines
wherever possible.
Chlorine is only slightly soluble in water. Theoretically, only about 0.7% chlorine can be dissolved in water
at 68 degrees F (20 degrees C). Practical solubility, which requires considerable mixing and time, is about
half this value. In conventional solution feed chlorinators, there is not sufficient time or mixing in the
ejectors and solution lines to get even this practical solubility. As temperature increases, the solubility drops
off very rapidly. The insolubility of chlorine in water was a major reason for the development of a vacuum
gas chlorinator system that separated the ejector from the vacuum regulating and chlorine flow metering
components.
Recognizing the relative insolubility of chlorine in water, it is possible to eliminate two very serious
problems that occur with all chlorinators that either incorporate their ejector in a floor cabinet or mount
them as an integral part of a wall-mounted system, or where the remote ejector is mounted some distance
from the actual point of chlorine application.
First, we have essentially eliminated corrosion of pipes, valves, etc. in the system being treated and, second
we’ve eliminated hazardous solution lines which contain a very corrosive liquid and a large quantity of
chlorine gas under pressure. Both of these problems have been eliminated simply by locating the ejector
directly at the diffuser where the resulting chlorine solution will be injected into the water or wastewater
being treated. In the REGAL system, the chlorine gas is conducted from the chlorinator to the point of
diffusion through a vacuum line. The gas is never above atmospheric pressure in this line. At the ejector
the chlorine gas is mixed with water (at vacuum conditions) and immediately injected into the treated
system through a diffuser. The chlorine that has not been dissolved in the water is in the form of thousands
of almost microscopic bubbles which, when entering the much larger flow of the main stream, is
immediately dissolved. However, if the solution discharging from an ejector is conducted to the diffuser
through a chlorine solution line, the very fine bubbles rapidly grow together (coalesce) into larger bubbles
and these larger bubbles contain chlorine, moisture and air, which do not quickly dissolve into the main
stream after leaving the diffuser. These larger bubbles travel along the top of the pipe, or collect in high
points to cause severe corrosion in the system being treated. Injection into the suction-side of pumps has
often met with strong objection because of severe corrosion that has occurred to the pump impellers and
other parts. With the REGAL ejector, close coupled to the diffuser at the point of solution injection into the
suction-side of the pump, we have not experienced this problem. However, with solution lines as short as 810 feet (3 meters) you can have bubbles ranging from 1/8” to 1/4” (0.3 to 0.64 cm) in size. A 30’ to 40’ (9
to 12 meters) length of solution line gives time to form bubbles 1/2” to 3/4” (1.2 to 1.9 cm) in diameter. In
addition, the formation of these larger bubbles in the solution lines themselves, often creates a serious
erosion along the top of the pipe or hose. This ultimately creates a weak spot in the solution line where
breakage or rupture can occur. This is not an uncommon occurrence.
Regulatory agencies and users often insist that the chlorinator and cylinders be isolated in a separate room.
This is a good idea. However, there has been little or no concern about the fact that a solution line from the
chlorinator ejector is carried outside the room – possible through a public area or through an area containing
critical equipment – and it may not even be protected from any physical damage by some type of conduit.
These solution lines are always under pressure and since they contain a highly corrosive solution and
undissolved chlorine gas, these lines should be considered as chlorine gas pressure lines. In addition, if a
“solution line” is cut or damaged, the chlorine gas will continue to escape into the area and strong, corrosive
chlorine solution will also escape. The chlorinator has no way of detecting this situation, and it will
continue to operate. When you consider this fact, and the fact that as much as half of the chlorine which has
gone through the chlorinator may still be in the form of gas, you can realize the hazard of chlorine solution
lines.
We have seen countless numbers of cases where no concern is given to a long length of unprotected solution
line, but there is great concern that the chlorine gas vacuum line be enclosed in a separate, sealed protective
conduit. If the vacuum tubing between the chlorinator and the ejector should be cut, air immediately enters
the cut in both directions and the chlorinator inlet safety valve closes tight at the cylinder. Visualize a piece
of vacuum tubing from our ejector passing through a room and also a solution line in a second chlorinator
passing through that same room. Cut the vacuum tubing and the chlorinator would shut off. You could
possibly detect a faint odor of chlorine, but this is doubtful. However, cut the solution line and you will not
only get sprayed with a strong corrosive and irritating solution, but it will probably be impossible for you to
remain in the room for more than 15 or 20 seconds due to heavy concentration of chlorine gas.
AVOID SOLUTION LINES WHEREVER POSSIBLE!
Hydraulic Considerations Involving Chlorine Solution Lines
Another drawback to solution lines, particularly long pipe runs, is the likelihood that this will force the use
of a larger booster pump than would be necessary if the ejector is installed directly at the application point.
Two distinct situations usually exist:
1.
It is required, for some reason, that the booster pump be located near the chlorination
equipment,
or
2. It is not important where the booster pump is located.
In the first case, where the booster pump is located near the chlorination equipment and some distance (for
example 100 ft or 30 meters) from the application point, we have to calculate the friction losses incurred in
the piping, since they can be quite significant. For purposes of this discussion we can ignore friction losses
in the booster pump suction piping since it would be essentially the same whether the ejector is located very
close to the booster pump with a ‘solution’ line running to the application point, or the ejector is installed
right at the application point. Assume a chlorine feed rate of 50 ppd (1000g/hr.) and a backpressure at the
application point of 60 psig (4.21 kg/cm2), and a standard REGAL ejector nozzle No. 17A.
Back Pressure

71 psig (5.0 kg/cm2)

131 (9.21)

18.5 (1.17)
20.0 (1.26)
Friction loss in 100 ft. (30 m) 1” SCH. 80 PVC = 11 PSIG (.77 kg/cm2)
A.
With Solution Line: Add the friction loss of 100’ (30 m) of the pipe to the backpressure. This gives
you an effective backpressure of approximately 71 psig (5.0 kg/cm2). The ejector supply pressure
must be at least 131 psig (9.21 kg/cm2). Therefore, the booster pump must raise the suction pressure
(assume 60 psig or 4.21 kg/cm2) at least 71 psig (5.0 kg/cm2).
B. Remote Ejector At Application Point: Add the friction loss of 100’ (30 m) of pipe to the ejector supply
pressure required (this is the amount of pressure loss between the booster pump and ejector inlet). The
backpressure is 60 psig (4.21 kg/cm2), the same pressure as the water to be treated at the application
point. The ejector supply pressure required for the back pressure is 109 psig (7.66 kg/cm2), but we add
the 11 psig (.77 kg/cm2) friction loss, so the effective booster pump outlet pressure must be at least
120 psig (8.44 kg/cm2). Therefore the booster pump must raise the suction pressure at least 60 psig
(4.21 kg/cm2).
In the above example you can see that the use of a chlorine solution line instead of ejector installation right
at the application point, results in a net increased booster pump requirement of 11 psig (0.77 kg/cm2). In the
actual practice, this difference would be greater due to increased ejector water flow requirements at the
higher backpressure, which itself creates additional friction loss, and so forth. The alternative is to increase
the solution pipe diameter (at significant cost increase) to reduce friction losses.
The second case, mentioned earlier, presents the ideal answer. Wherever possible, locate the booster pump
and ejector in the same area as the point of chlorine application, and just run chlorine vacuum tubing to the
ejector from the chlorinator. This eliminates friction loss problems, eliminates dangerous chlorine solution
lines, and reduces the required booster pump size significantly. In the same application example as above,
the booster pump would only have to raise the suction pressure by 49 psig (3.44 kg/cm2). Of course, both of
the “first case” examples ignored any friction losses in the booster pump suction piping, which would have
to be added to the “boost” requirements.
For practicality, economy and safety, place the gas chlorinator ejector as close as possible to the chlorine
application point.

SIZING GUIDE FOR REGAL GAS CHLORINATORS
The basic formulas for determining the proper gas chlorinator size is based on the maximum expected flow
rate of water or wastewater at any time and are as follows:
lbs./day chlorine - (0.012) X (flow rate in US gpm) X (dosage in ppm)
lbs./day chlorine - (0.015) X (flow rate in IMP. gpm) X (dosage in ppm)
gms./hr. chlorine - (3.6) X (flow rate in 1/s) X (dosage in mg/1).
Example:
A deepwell treatment station is pumping drinking water at a maximum rate of 1000 gpm. Water
quality is good with low chlorine demand and requires a chlorine dosage rate of 2 ppm to maintain required
chlorine residual:
lbs./day = .012 X gpm X ppm
lbs./day = .012 X gpm X 2
lbs./day = 24
Allowing for an oversizing safety factor of at least twice the required dosage rate, a 50 PPD REGAL Gas
Chlorinator is used.

manganese, unoxidized iron, sulfides, etc.
Dosage: Amount of chlorine, expressed in ppm or mg/1, which must be injected into water or wastewater
to satisfy the demand and maintain a required chlorine residual.
Residual: Chlorine remaining, after a specific contact time, which is still available for reaction.
Essentially, this is the amount of chlorine in excess of the DEMAND.
Free Chlorine Residual: That portion of the total chlorine residual that remains in the water or wastewater,
at the end of a specified contact period, which will react chemically and biologically as hypochlorous acid
or hypochlorite ion.
-2Combined Chlorine Residual: The portion of total chlorine residual that remains in the water (or
wastewater), at the end of a specific contact period, which will react chemically and biologically as
chloramines. (Chloramine is the combination of chlorine and ammonia).

CHLORINE WITHDRAWAL RATES
Despite the fact that direct-cylinder mounted gas chlorinators have been available for over 45 years,
there still remain many misconceptions and out-dated “rules of thumb” regarding the rates at which
chlorine can be withdrawn from 100 or 150 pound cylinders, using direct-cylinder mounted gas
chlorinators.
One of these misconceptions is you can only withdraw 40 to 50 pounds of chlorine per 24 hours
from a single chlorine cylinder. The actual basis for this idea goes back many years to the time
when the only type of gas chlorinator available was either mounted on a wall or in a floor cabinet.
These units were connected to either the chlorine cylinder or to a manifold by means of flexible
connectors. Users of these gas chlorinators were told to connect one (1) 100-pound or 150-pound
cylinder of chlorine to the chlorinator or chlorinator manifold for each 40 or 50 pounds per 24 hours
of chlorinator feed rate capacity.
At that time, all manufacturers of gas chlorinators had the same problems. Liquid chlorine could and
would be formed in the copper flexible connectors, and in the steel manifolds. There were already
so many points of potential pressure leakage that it really didn’t make much difference if one or
more additional cylinders were hooked up. At the time when the concept of mounting the
chlorinator directly onto the chlorine cylinder valve was introduced, maximum withdrawal rates
suddenly became important. The idea that only 40 to 50 pounds per 24 hours could be continuously
withdrawn from a single cylinder was pushed very strongly by gas chlorinator manufacturers who, at
that time, did not have a direct-cylinder mounted gas chlorinator to offer. Users were told that when
chlorine was withdrawn above these rates the chlorine would freeze; the valves would freeze up; the
chlorinator would stop working; liquid would be formed in the chlorinator; etc. This issue was
pushed very strongly in the 1960s and consequently remains in the minds of many people today.
The primary facts stressed at that time seemed to indicate that the Chlorine Institute clearly states
that only the low withdrawal rates are possible. Many people today will still steadfastly maintain
that the Chlorine Manual, published by the Chlorine Institute, contains a statement to this effect. In
actuality, the Chlorine Manual clearly spells out the findings of the Chlorine Institute with regard to
chlorine withdrawal rates. It states, first, that the dependable continuous discharge rate of gas from a
single 100 or 150 pound cylinder is about 1 ¾ pounds per hour, which is about 42 pounds per day.
This, however, is stated to be under the conditions of 70°F when discharged against a back pressure
of 35 psi and without the cylinder sweating on the outside. These findings also indicate that if
sweating can be tolerated, these rates can be doubled. This takes us up to 84 pounds per day. It
makes little difference to anyone whether or not the outside of the cylinder has sweat or
condensation on it, and it certainly has no effect on the operation of the chlorinator. The
item that is most often overlooked is the fact that this data is given for discharging against a 35 psi
back pressure. With a vacuum operated, solution-feed gas chlorinator mounted directly onto the
chlorine cylinder valve, the discharge is not against a positive pressure, but is actually against a
controlled negative pressure of about 2 psi below atmosphere.
To further verify this, data was obtained from tests made by one of the leading chlorine producers
which showed a continuous withdrawal rate of above 125 pounds per day. They were discharging
against 0 (atmospheric) pressure. Additional tests were conducted during the winter and a 100pound chlorine cylinder was placed out-of-doors at 20°F and left out-of-doors several days. At the
time this test was conducted, the actual liquid chlorine temperature was 20°F. A 100 PPD
chlorinator was connected to the cylinder valve and operated at above 100 PPD continuously.
Higher than maximum capacity was withdrawn until the liquid was almost exhausted, at which time
the rate dropped to about 60 pounds per day for only a few minutes until the chlorine cylinder was
empty.
Figure 1 illustrates the rate of chlorine discharge in pounds per day from a 150-pound cylinder, at
70°F, into the atmosphere (no back pressure) over a period of 20 hours. Curve “A” shows the rate of
chlorine discharge over any given period of time when air is circulated by a fan blowing against the
cylinder. Note that in this case maximum chlorine discharge rates are continuously maintained at
over 200 pounds per day and that the entire cylinder was exhausted in just 8 hours. However, more
normal conditions are represented by Curve “B” where no air is circulated past the cylinder by a fan.
Curve “B” illustrates the fact that at least 100 pounds per day of chlorine can be discharged
continuously against a 0 psi back pressure. In fact, the entire 150 pounds of chlorine contained in
the cylinder would be exhausted in just 20 hours at 70°F.
Figure 2 illustrates the same data as above but it is expressed in terms of the total pounds of chlorine
which are discharged over a given elapsed time, with the same conditions as stated for Figure 1. It
should be noted that in the case where air is not circulated against the cylinder by a fan, as in Curve
“B”, 100 pounds of chlorine will be discharged in less than 9 hours.
Another misconception that has managed to survive after all of these years is the story that if
chlorine is withdrawn at too high a rate from a single cylinder, the chlorine will freeze. This is
impossible. Chlorine freezes at approximately -150°F. The pressure in the cylinder changes only
with the temperature change and has nothing to do with the amount of liquid left in the cylinder. A
certain lack of understanding on this point has led many people to believe that a chlorine pressure
gauge installed in the system will somehow let them know how much chlorine remains in the
cylinder. The vapor pressure curve presented in the Chlorine Manual shows that the cylinder
pressure at 80°F is 102 psi. At 60°F the pressure is 71 psi at -30°F the pressure in the cylinder
finally drops to 0 psi.
A direct-cylinder mounted gas chlorinator will actually draw about a 2 pound vacuum in the
cylinder. As gas is taken out of the cylinder the pressure in the cylinder is reduced which causes the
liquid in the cylinder to boil. This boiling obviously requires heat which is supplied by the
temperature of the air around the cylinder. At high withdrawal rates the temperature of the outside
of the cylinder adjacent to the chlorine liquid surface is lowered and this will eventually cause
condensation of moisture to form on the outside of the cylinder. At very high withdrawal rates the
temperature at this surface may drop below 32°F and the condensation will freeze to form a frost
layer. This is the same thing that can happen in valves, flexible connectors or manifolds where the
chlorine gas has gone back to liquid state and is then rapidly re-evaporated. Obviously there is no
freezing on the inside and the frost is merely an indication of the outside surface temperature and
high humidity. This is no different than frost forming on refrigerator coils and certainly the
refrigerant inside the coils is not frozen. An examination of the chlorine vapor pressure curve,
shows that as the temperature of the liquid—and consequently, the pressure—becomes lower and
lower you finally reach an equilibrium condition. At this point, the amount of gas that can be
withdrawn from the cylinder is strictly a function of how much heat can be supplied from the
atmosphere. Since the withdrawal rate is now limited, the cooling effect due to evaporation remains
constant.
Let us examine for a minute the condition that exists when a gas chlorinator is hooked up to a
cylinder by means of a flexible connector. The pressure inside the chlorine cylinder, the flexible
connector, and in the gas manifold is constant since the cylinder valve is open and there are no
points of pressure reduction. The cylinder itself is essentially a boiler with a very heavy steel wall.
The flexible connector is comparable to a condenser tube with the surrounding air being the cooling
medium. Since this system contains both liquid and gas phase, any decrease in temperature will
cause some of the gas to go back to liquid. What often occurs is that a door or window is opened to
cool off the room, or thunderstorm or other change in weather causes the room to cool. Even sun
through a window hitting the cylinder, but not hitting the flexible connector, can cause the connector
to be at a lower temperature. Any slight differential in temperature that occurs will cause gas in the
flexible connector and manifold to change to liquid. This liquid passing through the lines will
actually tend to scrub the copper and steel so that when the liquid re-evaporates, dirt will be
deposited. This remains the greatest single source of chlorinator failure and maintenance in noncylinder mounted gas chlorinators. All chlorinator systems having flexible connectors and
manifolds should either be in a temperature controlled room or have special heaters on the
connectors and manifold to make sure that they are at all times at a higher temperature than the
cylinder. A direct-cylinder mounted gas chlorinator is not susceptible to this problem since cylinder
pressure is immediately reduced to a vacuum as the gas leaves the cylinder valve and enters the
chlorinator, imparting what is known as “superheat” to the gas, making condensation of the gas back
into a liquid a physical impossibility.
