Flanged Immersion Heaters

FH Series Flanged Immersion Heaters consist of a number of "U" bend tubular heating elements welded into a standard ANSI pipe flange. Elements are supported with TEMA-style baffles. A thermowell is installed through the center of the flange for the over-temperature sensor. 

Flanged Immersion Heaters are easily installed by direct mounting to a tank, pipe, or vessel through a mating flanged nozzle. Each heater is shipped with a spiral wound mounting gasket. 

Flanged Immersion Heater Capabilities

These immersion heaters are provided with a NEMA-rated enclosure to protect the heater element terminations and pre-bussed circuitry.  The standard enclosure allows for the customer to locate conduit knock-outs as required for field wiring.  

Our designs are capable of heating water, air, steam, gas, light oils, heavy oils, thermal fluids, and chemicals. Maximum design temperature is 1,200°F, depending on the medium being heated.
