Screw plug and flange immersion heaters

Screw plug and flange immersion heaters are devices designed to heat a fluid (liquid or gas) by natural or forced convection (circulating fluid). The heating elements are in direct contact with the fluid. The fixing interface for mounting the immersion heater to the fluid container is a threaded plug (ISO metric or BSPP) or a flange. Some models can be fitted with a thermostat, a Pt100 sensor or a thermocouple for safety or regulation and a connector protection box.
