Description
Topic ”NITROX”:
A new trend has developed amongst divers that dive for fun enabling them to stay under water longer, to achieve the pleasure
of shorter decompression times and reduce the physical strain
of diving. For this purpose the proportion of nitrogen in the
breathing air, which has a negative effect on the body whilst diving, is reduced. At the same time this then causes an increase
in the proportion of oxygen. This is achieved with the help of
special oxygen--membranes that remove an adjustable quantity of nitrogen from the air, according to the content of oxygen
desired. Concentrations of 32, 34 and also 36% are normal and
in special cases even 40% and more. Conventional membranes cannot achieve concentrations over 40% proportion of
oxygen, even under ideal conditions, so mixtures above that
are only possible using the partial pressure method (mixing with
pure oxygen).
2.
Generating Nitrox mixtures and filling
into diving tanks:
Usually a low pressure compressor pumps the air into the membrane at a pressure of approx. 4--10 bar, however to guarantee
satisfactory functioning of the membrane you must pay particular attention that the air is completely free of oil and the saturation with water is below 100%. The membrane needs approx.
2,5 -- 3 times more air than the downstream high pressure compressor to provide the delivery quantity required. After being in
the membrane, the air then flows into the high pressure compressor (just above atmospheric pressure) and is compressed
at up to a pressure of 225 bar (330bar is not allowed at the moment). After that it is filled into specifically marked pressure
tanks that have nitrox--specific screw threads (DIN EN 144--3).
3.
Compression of Nitrox mixtures in high
pressure piston compressors:
The nitrox mixture is sucked in at atmospheric pressure and
compressed to up to 225 bar with multiple stage (four stages)
compressor. The air is warmed up to 250 C at each individual
stage of compression and then cooled down to approx.
10--15 C above ambient temperature. Afterwards the air is
freed from oil residues in special filters and from humidity up to
a certain degree, so that a high quality breathing air mixture is
generated.
4.
B- TROX Systems design
See flow diagram 82627 in the appendix.
The air that has been compressed to approx. 7--10 bar (oilfree!)
with a low pressure compressor (screw compressor) is cleaned
of particles by the filter unit D11.1--D11.2. Afterwards the pressure reducer J7 regulates the exact admission pressure for the
oxygen membrane that is responsible for ensuring sufficient airflow at the membrane outlet.
Fig. 1
B--Trox Membrane Unit
The air which has been cooled down to 20 C 5 C flows into the
Oxygen membrane. The membrane separates approx. 2/3 of
the volume flow in the form of nitrogen. With the removal of nitrogen the rest of the gas has a higher proportion of oxygen
which, depending on the setting can be between 28% and 40.
After the membrane, the oxygen proportion is measured by
means of a chemical--oxygen sensor as well as an optical display. Two safety valves U6 and R4 make sure neither too big a
pressure burden nor a vacuum develops.
The Nitrox--gas mixture generated in this way is conducted via
a hose line to the high pressure compressor.
An additionally mounted ball valve V7 makes it possible, via
change--over system to also compress ”normal breathing air” .
The air, which is still warm, then flows through the W6 refrigerative dryer where it is cooled down and dried slightly.

Filter Unit
The filter unit is fed with pre--compressed air from the low pressure compressor.
The filter unit consists of:
Prefilter:
5,0 mm
Fine particle filter:
0,010 mm
Filter efficiency:
99,99%
Both filter units have a condensate separator as well as an automatic condensate drain. The fine particle filter has a filter cartridge monitoring system as well.
This indicates a pressure drop when the filter cartridge gets too
dirty. (Fig. 3, red area).

6.
Pressure reducer:
The pressure reducer serves the purpose of reducing the pressure delivered from the low pressure compressor to 7 -- 10 bar
before reaching the membrane.
Depending on the admission pressure the flow rate (Nitrox)
after the membrane can be influenced, making it possible to
avoid overpressure or negative pressure (vacuum).
The admission pressure depends on the intake power of the
high pressure compressor and the type of membrane used.
Aim for O bar (atmospheric pressure) at the outlet pressure
gauge as an optimal setting value. (Fig. 4).

Refrigerative dryer
The refrigerative dryer’s main task is cooling the compressed
air and not drying it.
The refrigerative dryer can keep the compressed air constant
at approx. 20 5 C , even when the ambient temperature rises to
a max. of 50 C.
After the system has gone through a certain running--in period
(15--20 min) it becomes independent of the outside temperature; it is then no longer necessary to readjust the values once
set.
The running--in time is necessary to allow all the system’s components which come in contact with the medium Nitrox to cool
down to the processing temperature of 20 C.
The outlet temperature is indicated on the thermometer (Fig. 5).
At low temperatures the regenerative dryer doesn’t have to take
over any cooling down function and Nitrox can be generated immediately. The temperature regulator is already preset and
needs no alteration (Fig. 7).
The indicated pressure of the brine should not drop below 1 bar
otherwise it has to be topped up with water (Fig. 6).

Oxygen membrane:
The oxygen membrane requires an admission pressure of 5 to
10
bar, according to the delivery quantity of Nitrox desired and the
content of oxygen (depending on the downstream high pressure compressor)
Oxygen
membrane
Mode of operation:
The compressed air flows through the bundled hollow fibres in
the membrane.
Oxygen diffuses very quickly due to the fibres, whereas nitrogen diffuses very slowly or not at all.
The retained nitrogen, which is regulated via a valve (fig. 9), is
blown out at the upper side of the membrane. The content of nitrogen that comes out at the lower outlet of the membrane adjusts itself according to the level at which the nitrogen drainage
is set at.
Make sure there is sufficient ventilation. In
rooms which are well ventilated, pay attention that the discharged nitrogen is transported into the fresh air. Otherwise the concentration of nitrogen can become too high
and damage your health.

Monitoring the Nitrox
After coming out of the membrane (outlet pressure = atmosphere), the generated Nitrox is monitored by two safety valves.
One monitors for overpressure (set value 200mbar), the other
one takes on the task of a vacuum valve.
This avoids harmful overpressure or negative pressure peaks
reaching the downstream high pressure compressor.
A pressure gauge additionally indicates the current outlet pressure (fig. 11).
Make sure that with a connected high pressure compressor, the
pressure gauge indicates 0.

Metering the oxygen
As part of the Nitrox monitoring system already mentioned, an
oxygen sensor continuously controls the concentration of oxygen of the generated Nitrox gas mixture. The measured value
is indicated on the controlling device at the control panel.
For calibration purposes the oxygen sensor has to be removed
from the collecting rail and the CAL key pressed for approx. 3
secs. The adjustment in accordance to the ambient then takes
place. During this, the status of the sensor (should be 100%) is
briefly indicated. Afterwards it displays the oxygen content.
O2 display unit
If the sensor is calibrated when the outside temperatures are
high, you have to wait a certain period of time (usually 5 mins)
after mounting it in the cooler Nitrox flow to allow for the sensor
to adjust to the temperature.

Notices of danger regarding pressure vessels
• Never open or loosen pressure vessel lids or pipe connection parts under pressure; always depressurise the vessel
or the unit.
• Never exceed the permissible operating pressure of the
vessels!
• Never heat the vessels or any of their parts above the
stated, maximum operating pressure.
• Always exchange damaged pressure vessels completely.
Individual parts that are subject to pressure loads cannot be
purchased as spare parts, since the vessels are tested as
a complete part and the documentation considers them as
a whole (see pressure vessel documentation, serial-numbers!).
• Always pay attention to the permissible operating mode of
the pressure vessels.
We differentiate:
-- vessels for static load
-- vessels for dynamic load
Vessels for static load:
These pressure vessels are permanently under virtually
constant operating pressure; the fluctuations of pressure
are very small.
Vessels for this type of load are not marked in a particular
way and may be used as long as the vessel inspections,
carried out regularly, do not uncover any safety--relevant
deficiencies.
We recommend that aluminium vessels should be exchanged after 15 years at the latest.
Vessels for dynamic load:
These pressure vessels may also be used under conditions
of changing operating pressure. The pressure may vary between the atmospheric and the maximum admissible operating pressure.
The pressure vessel documentation and the appropriate
notes in the operating manual particularly characterise
vessels of this type as being adequate for dynamic loads.
In the technical information for these vessels you will find
specifications concerning their permissible operating
period.
Due to the variation of the operating pressure, these vessels
are subject to a so--called dynamic load, which puts the
vessels under great stress. The change between two different pressures is called a load change or cycle. In the technical information for these vessels you will find specifications
concerning the permissible number of cycles depending on
the fluctuation of the operating pressure.
Having reached half the permissible number of cycles, the
vessel has to be submitted to an internal check, in which the
critically stressed areas of the vessels are examined by
means of suitable testing methods, in order to ensure the
operating safety.
After having reached the total permissible number of load
cycles, the vessel must be exchanged and scrapped.
Record the number of load cycles in writing if you do not
have an automatic cycle--counter.
We recommend that aluminium vessels should be exchanged after 15 years at the latest.
Please pay attention to and follow these measures, for your
own safety and that of you employees and customers!
In order not to unnecessarily load the pressure vessels
additionally, the non--return valves, that are meant to avoid
a drop in pressure, and also the pressure maintaining
valves, which should reduce big pressure fluctuations as
well, should be checked regularly for internal and external
tightness and functionality.
• Check the pressure vessels regularly on the inside and outside for damage from corrosion.
• Be particularly careful with second--hand pressure vessels,
when their previous operating mode is not specifically clarified.
SAFETY REGULATIONS (EC; partly Germany, only)
A compressor is identified by German law as being a filling system if pressure cylinders are filled by the system, especially
when these cylinders are made available for third parties. The
11
start--up and operation of compressor systems for use as filling
stations is governed by the following regulations:
a-- Pressure vessel directive (Directive 97/23/EC) of
29.05.1997

c-- Machine safety law (GSG) as of 11.05.2001
d-- 14th regulation to machine safety law (14. GSGV -- pressure vessel regulation) of 03.10.2002
e-- Technical regulations for pressure gases (TRG 400, 401,
402, 730).
If a high pressure compressor is used for filling pressure
vessels or for the supply of pneumatic systems, the following regulations apply:
f-- Accident Prevention Regulations (UVV):
• UVV compressors (VBG 16).

The manufacturer has complied with all applicable regulations
and the unit is prepared accordingly. If desired, we offer at our
Munich site a partial acceptance test according to § 14 BetrSichV. Please contact our Technical Service Department with
regard to this. They can also supply our leaflet “IMPORTANT
NOTES FOR CERTIFICATION”.
According to the operation safety regulations (BetrSichV), all
compressor units which will be used as filling stations must undergo an acceptance test by a professional at their location before bringing them into service. If pressure vessels (bottles) are
to be filled by the compressor for a third party then the appropriate permission must be obtained from the responsible authority
before the acceptance test. As a rule, this is the factory inspectorate. The procedure for obtaining permission is according to
TRG 730, guidelines for permission to set up and operate filling
stations. The test certificates and documents delivered with the
compressor are important and may be requested during the
procedure for obtaining permission. In addition, the documents
belonging to the unit are important for recurrent inspections and
should therefore be carefully kept.
Inspections in accordance with the regulations for prevention of
accidents will be carried out by the manufacturer or by a specialist.
No guarantees whatsoever are valid for damage caused or favoured by the non--consideration of these directions for use.
We strongly emphasize these regulations.

Installation
When installing the filling station you must observe the Technical Regulations for Pressurized Gases TRG 401 and the instructions relevant to installation listed there.
The filling station is to be mounted at a suitable operating
height. Fix it with the four bore holes ( Ø 10 mm) at the rear side
with appropriate screws (not included in the delivery scope)
14.
Operation
Make sure that all persons handling the filling station are familiar
with the function of all controls and monitors. In particular make
sure the safety regulations in chapter C are observed.
Every time the unit is started up check all systems for proper
operation. If any malfunction is observed stop the unit immediately and find the cause of the fault, or call the service department.
•
Switch on high pressure compressor.
•
Using the outlet pressure gauge, with the help of the pressure reducer, set the admission pressure so that the pressure gauge indicates 0 bar.
•
Check oxygen content again.
•
System is ready for filling.
Prior to each operation check all seals and
external connection threads for dirt and damage.
In order to eliminate any risk of fire or explosion, the grease has been meticulously
removed from this unit’s oxygen pipe lines
and they have been cleaned. It is imperative
that this degree of cleanliness is kept, for this
reason any contamination from oil, grease,
solvents or corrosion must be avoided.
The operator must ensure utmost personal
cleanliness. Keep hands, clothing or dusters
that are dirty with oil or grease away from the
unit.
PROCEDURE FOR INSTALLING THE SYSTEM
•
Switch on the low pressure compressor and the regenerative dryer (high pressure compressor does not have to be
switched on yet)
•
Confirm what delivery quantity has to be available at the
B--Trox--outlet (e.g.: 320l/min)
•
Referring to a table in the instruction manual, roughly set the
admission pressure at the pressure reducer.
•
Set the oxygen content wanted at the oxygen valve. (if
necessary, calibrate the oxygen sensor first; see instruction
manual, oxygen measuring device in appendix).
•
At high outside temperatures (above 30 C), run the unit in
idle mode at least 15 mins.
•
Check the thermometer at the Nitrox outlet and wait until the
temperature has dropped below 25 C.
•
Afterwards regulate the oxygen content again (if necessary)

Maintenance work
VORSICHT
Only ever do any maintenance and repair work at the filling station when the
system is without pressure.
VORSICHT
Do not solder or weld any pressure lines.
Check the whole unit regularly to make sure
it’s impermeable. To do so, check all fittings
and screw fittings with special leak detection
spray (pat no. FM0089). Repair any leaks.
Make sure all materials are suitable for using
with oxygen.
MAINTENANCE INTERVALS
Once after first operation
Interval
Prior to first operation
Type of maintenance work
Check to make sure fixing screws are tight, check all screwed fittings are impermeable.
Periodically according to the calendar
Interval
Type of maintenance work
Daily, before or when putting
into operation
Check all threads at air inlet and Nitrox outlet for damage
Weekly or as required
Check impermeability of the system
As required
Exchange oxygen measuring device sensor
Annually
Check that all flexible lines are in a safe condition for operation (intact and impermeable)
Every 1000 operating hours or Exchange filter cartridge in fine particle filter
at least once a year
Every 5 years
Send in the filling station or have it checked by a specialised company
MAINTENANCE RECORD
We recommend that all maintenance work is recorded in a service book, showing the date and details of the work carried out.
This will help to avoid expensive repairwork caused by missed
maintenance work. If it is necessary to claim against the warranty, it will help to have proof that regular maintenance work
has been carried out and that the damage has not been caused
by insufficient maintenance. Please refer to section 23 of our
general terms and conditions. For this purpose, the following
maintenance control sheets are provided (copy as required).
Please fill in the appropriate lines to show what maintenance
work has been carried out, and sign and date.

FILTER SYSTEM
Changing the cartridge
---
----
Discharge filter housing of pressure with the air bleed valve
until the pressure gauge indicates 0 bar.
Exchange the filter cartridge in the fine particle filter every
1000 operating hours or at least once a year. To do so unscrew the filter screw fittings anti--clockwise. Tool: strap
wrench, hook wrench.
Unscrew old cartridges and dispose of them
Screw in new cartridge. Only hold the cartridge at the bottom
and tighten it to max. 2 Nm.
Put the screw fitting on again, tighten it with your hand.
OXYGEN MEASURING DEVICE
The sensor has to be replaced regularly.
See enclosed instruction manual.
