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 of our electric immersion heaters is shipped with a spiral wound mounting gasket. 

Flanged Immersion Heater Capabilities

Flanged 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 electric immersion heater 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.
