Technical Data
   
   

Circulation Heaters consist of an insulated pipe body containing a Screw Plug Heater or Flanged Immersion Heater assembly. They are designed to heat moving air, gases or liquids through the vessel in a single pass or re-circulating, multi-pass system. These units can be mounted horizontally or vertically and are available with a variety of pipe thread and flanged inlet and outlet options. Terminal housings are available for indoor, outdoor (weather-proof NEMA 4) and hazardous (NEMA 7) environments. Many options are available including thermostats, high limit and process thermocouples or RTD sensors.
