Rev 1 (4-14)
Tempco Screw Plug Immersion Heaters are UL recognized and
CSA certified in many design variations. The UL File Numbers
are E90771 (CCN UBJY2/8) for heaters not containing a
thermostat and E234452 (CCN KSXF2) for heaters used in water
based solutions that include a thermostat. Tempco’s equivalent
CSA file number is 043099. Screw Plug heating elements and
assemblies with thermostats have additionally been evaluated to
UL574 (File Number MP4154) under CCN MDST2/8 for
oil heating applications.
If you require UL, CSA, or other NRTL agency
approvals, please specify when ordering.

Tubular Industrial Process
Checklist — Selecting the Proper Screw Plug Heater
Determine a Safe and Efficient Element Watt Density
Element Watt Density is the wattage dissipated per square inch of the
element sheath surface and is calculated with the following formula.
Watt Density
=
π × element dia. × element heated length
element wattage
For a particular application, element watt density will govern element sheath temperature.
Factors to consider when choosing a suitable watt density are:
1. Many materials are heat sensitive and can decompose or be 3. When heating hard water and cleaning solutions mineral
damaged if the element is running too hot.
deposits can build up on the element sheath, acting as a heat
insulator and raising the internal element temperature. If

vent element overheating.
Select the Element Sheath Material
Sheath Material Selection
CORROSION. In addition to selecting a sheath material that is compatible with
the heated medium, other factors that affect corrosion need to be considered.
1. The temperature of the corrodent. As temperature increases the
degree of corrosion increases. Also remember that usually the
element temperature is higher than the material it is heating.
2. The degree of aeration to which a corrodent is exposed.
Stagnant conditions can deprive the stainless steels of oxygen,
which is required to maintain their corrosion resistant surface.
3. Velocity of the corrodent. Increased velocity can increase the
corrosion rate.
Note: See pages 16-12 through 16-20 for the recommended
sheath materials for many immersion heating applications.
If you are purchasing the material you are heating, check
with the supplier for their recommendations.
Typical Applications
Copper Sheath—Process water, water with very weak chemical solutions, demineralized, deionized or pure water, hot water storage for washrooms, showers, cleaning
and rinsing parts, for freeze protection of cooling towers and sprinkler systems and other
aqueous solutions not corrosive to copper sheath. Sheath temperatures to 350°F (177°C).
Incoloy® Sheath—Weak chemical solutions, oils, tar, caustic soda, detergent, alkaline
solutions, molten salts, demineralized, deionized or pure water (sheath passivation is
recommended), and other aqueous solutions not corrosive to Incoloy® sheath. Air, gas
mixtures and superheated steam. Sheath temperatures to 1600°F (871°C).
Steel Sheath—Fluid heat transfer media, tar, high to low viscosity petroleum oils,
asphalt, wax, paraffin, degreasing solvents, alcohol, molten salt, and other solutions not
corrosive to steel sheath. Sheath temperatures to 750°F (399°C).
Surface Treatments for Stainless Steel and Incoloy® Elements
and other Wetted Parts to Improve Corrosion Resistance
Screw Plug Immersion Heater surfaces in contact with the material being heated can be passivated or
electro-polished to improve their resistance to corrosion.
Passivation removes surface contamination, usually iron, so
that the optimum corrosion resistance of the stainless steel is maintained. Surface contamination would come from the small amount
of steel that may be worn off a tool during the manufacturing
process. Passivating is accomplished by dipping the heater in a warm
solution of nitric acid.
Electro-Polishing is an electrochemical process that removes
surface imperfections and contaminants, enhancing the corrosion
resisting ability of the stainless steels. The resultant surface is
clean, smooth and bright. Many medical and food applications
require this finish.

Select the Terminal Housing Type
Standard catalog screw plug immersion heaters are supplied with the
Type 1N general purpose (NEMA 1) terminal housing with a single
Dual 1/2-3/4 conduit knockout as shown on page 11-2. Additional
housings with and without a thermostat include:
Explosion resistant terminal housings are
intended to provide containment of an explosion in the enclosure only. No portion of the
heater assembly outside the enclosure is covered under this NEMA rating. Abnormal use of a
heater which results in excessive temperature can
create hazardous conditions such as a fire. Never perform any type of service nor remove the housing cover
prior to disconnecting all electrical power to the
heater.
Moisture Resistant (NEMA 4)
Explosion Resistant (NEMA 7)
Moisture/Explosion Resistant (NEMA 4/7)
If the housings on this page do not meet the size, construction or other
criteria of your application, consult Tempco with your requirements.

Wiring Diagrams — Screw Plug Heaters with Two Elements
Note: Dual-Voltage
heaters are factory wired
for the higher voltage
(series connection) unless
otherwise specified. Easily
rewired for lower voltage
operation (parallel connection).
Wiring Diagrams — Screw Plug Heaters with Three Elements
NOTE: Standard screw plug immersion heaters with three
elements, factory wired for three-phase delta, can be rewired
for single-phase operation with no wattage change. Wattage
can be reduced to one-third of the designed wattage by
switching from three-phase delta to wye connection.
Heaters wired for three-phase wye should not be
changed to single-phase or three-phase delta connection,
since this will increase wattage and watt density on the
elements by three times the original designed wattage,
causing premature heater failure.

Bulb & Capillary Thermostats
Thermostat Styles and Selection
Construction Characteristics
This type of control operates by expansion and contraction of a liquid in response to temperature change.
Liquid contained within the sensing bulb and capillary
flexes a diaphragm, causing the opening and closing of
a snap-action switch. For heating applications the contacts
are normally closed and open on temperature rise.

Warnings & Recommendations
1. Do not use the thermostat as a power switch. Use some other
means of disconnecting power to the heater for servicing.
2. A thermostat is not a fail-safe device. Use an approved high
temperature limit control and/or pressure limit control for
safe operation.
3. Avoid kinking or bending the capillary tube too sharply as
this will alter the calibration and/or render the thermostat
inoperable.
4. Excess capillary tube should be coiled neatly in junction box.
5. The capillary tube must never touch the thermostat contacts
as this will create an electrical short capable of harming
personnel and/or equipment.

The Stuffing Box Assembly is used to seal
the thermostat capillary when the sensing
bulb (3/8" max. OD) is immersed directly
in a liquid rather than in a thermowell. The
Stuffing Box consists of six slotted washers used to compress a graphite packing
into a 3/8" NPT male pipe thread fitting.
Assembly Instructions
Feed sensing bulb through hole in upper
and lower fitting. Insert washers and packing into top cavity of lower fitting. Upper
fitting then screws into lower fitting, creating the seal.

Standard (Non-Stock) Self-Contained Immersion Heaters
Design Features
This immersion heater is specifically designed for commercial dishwashers and sterilizing equipment. However,
due to the unique construction characteristics of these
heaters, they are readily adaptable for use in other water
heating applications. The heating elements are prewired
to a Definite Purpose contactor, thermostat and high limit
cutout. The thermowell is located at the top of the element bundle for fast shut-off response, preventing overheating due to low water level conditions.
✴ 2" NPT Brass screw plug
✴ Three Incoloy® 800 tubular elements
✴ Thermostat — 60°F (15°C) to 250°F
(120°C) range
✴ 350°F (177°C) Over-temperature
cutout with manual reset
✴ Internal Definite Purpose contactor
with 120V holding coil
✴ NEMA 4 moisture resistant housing
✴ Silicone resin element seal standard
Optional Mounting Kit (Part Number KTT00281) — Clamping nut, flat washer and
gasket for mounting heater in thin wall tanks with a 2-3/8" (60 mm) diameter opening.
