Circulation heaters are mounted within a thermally insulated vessel through which liquid or gas passes. The contents are heated as they flow past the heating element, making circulation heaters ideal for water heating, freeze protection, heat transfer oil heating, and more.
Circulation heaters are powerful, electric in-line heaters constructed of a screw plug or flange-mounted tubular heater assembly installed into a mating tank or vessel. Non-pressurized or highly pressurized fluids can be heated very effectively using direct circulation heating.
