Flange Heaters

Flange immersion heaters are designed for use in tanks and pressurized vessels to heat both gases and liquids. A flanged immersion heater will typically mate with a companion flange that is either welded to a tank or in the case of circulation heaters, to a pipe body. AccuTherm flange heaters are designed to provide our customers with a long-lived, dependable, trouble-free heater for their application requirements. A properly designed flange heater will provide a high degree of efficiency as the energy that is generated is quickly dissipated directly into the medium that is being heated.
