Immersion Heaters / Flanged
Flanged immersion heaters are high capacity electrical heating units made for tanks or pressurized vessels. They consist of multiple tubular heaters formed into hairpin and welded or brazed to flanges. The heating elements could be made of copper, steel, stainless steel or Incoloy sheath. Standard flanges are carbon steel rated for 150 or 300 Lbs. Other flange materials and shapes are available. Various types of electrical protection housing, built in thermostats, thermocouples and high limit switches can be incorporated.
