Watlow flanged immersion heaters are
easy to install and maintain. Designed for heating liquids and gases in tanks
and pressure vessels, ANSI flanged immersion heaters are ideal for applications
requiring higher kilowatts.
Watlow flanged immersion heaters are
made with WATROD or FIREBAR tubular elements brazed or welded to a flange.
Stock flange heaters are equipped with a general purpose terminal enclosure.
Watlow Flanged immersion heaters, with FIREBAR elements,
also answer the need for liquid immersion applications requiring high kilowatts
in small tanks. The FIREBAR element's unique flat surface geometry packs more
power in a smaller bundle, with lower watt density, making it especially
well-suited for petroleum-based liquid heating applications.
Features and Benefits:
UL® and CSA component recognition.
ANSI and ANSI compatible 2, 2½, 3 thru 48 inch flanges.
Integral thermowells provide convenient temperature sensor
insertion and replacement without
draining the fluid being heated.
Standard, general purpose terminal
enclosure for easy access to wiring.
All units are inspected and/or tested
to ensure element-to-flange pressure seals do not leak.

Options
Terminal Enclosures
General purpose terminal
enclosures, without thermostats, are standard on all flange immersion heaters.
Optional terminal enclosures include:
• General purpose
with a single or double pole thermostat.
• Moisture
resistant. Available with or without a single or double pole thermostat.
• Corrosion
resistant. Available with or without a single or double pole thermostat.
• Explosion
resistant Class 1, Div. 1 and 2, Groups B, C and D, T1-T6. Available with or
without a single or double pole thermostat.
•
Explosion/moisture resistant combinations. Available with or without a single
or double pole thermostat.
Stand-off Terminal Enclosures
Stand-off terminal enclosures provide an air-insulating barrier
between the flange and terminal enclosure by mounting the terminations and
wiring away from the flange. Stand-off terminal enclosures are recommended
whenever a process operating temperature exceeds 210°F (100°C). This helps
minimize terminal enclosure temperatures.
Certified Enclosures
CSA, ATEX, IECEx or PESO
certified enclosures protect wiring in hazardous gas environments.
ASME Pressure Vessel Code Welding
Flange assemblies can be
provided with an ASME Section VIII, Div. I pressure vessel stamp upon request.
Thermostats
To
provide process temperature control, Watlow offers optional single pole, single
throw (SPST) and double pole, single throw (DPST) thermostats.
Unless otherwise specified,
thermostats are mounted inside the terminal enclosure. Please verify that the
thermostat’s sensing bulb outside diameter is compatible with the flange
heater’s thermowell inside diameter.
Thermocouples
ASTM
Type J or K thermocouples offer more accurate sensing of process and/or sheath
temperatures. A thermocouple may be inserted into the thermowell or attached to
the heater’s sheath.
Thermocouples
are supplied with 120 in. (3050 mm) leads (longer lead lengths available).
Unless otherwise specified, thermocouples are supplied with temperature ranges.
Using
a thermocouple requires an appropriate temperature and power controller. These
must be purchased separately. Watlow offers a wide variety of temperature and
power controllers to meet virtually all applications. Temperature controllers
can be configured to accept process variable inputs, too. Contact a Watlow representative
for details.
To
order, specify Type J or K thermocouple and lead length. Indicate if the thermocouple is
for process temperature sensing or
heater sheath high-limit protection. Please specify if the flange heater will be mounted vertical
or horizontal in the tank. If vertical, specify if the housing is on top
or bottom.
If the flange heater is part
of an in-line circulation heating application, indicate flow direction relative
to the heater’s enclosure.F
Wattages and Voltages
Watlow
routinely supplies flange immersion heaters with 240 to 480VAC as well as
wattages from 150 watts to one megawatt.
If required, Watlow will make
heaters with voltage up to 600VAC and wattage beyond one megawatt.
