ATEX Immersion Heater | Zone 1 & Zone 2 (IIA, IIB, IIC) Hazardous Areas

EXHEAT RFA-CA hazardous area immersion heater provide certified heating for Zone 1 & Zone 2 (Flammable Gas) hazardous areas and explosive atmospheres according to ATEX Directive. Including hazardous area applications suitable for heating all process liquids or gases which are non-corrosive to the materials of construction.

The EXHEAT RFA-CA offers a hazardous area heating solution for oil and similar applications where low heat density is required.  A robust flameproof terminal enclosure protects the electrical connections. The watts density of the element core fitted depends upon the media to be heated and the kilowatt rating required.

Typical applications for the EXHEAT RFA-CA hazardous area flameproof cartridge immersion heater include tank heating for oil and water, frost protection and boiler equipment.

The immersion heater is suitable for applications with ambient temperatures between -40°C to +40°C and the terminal enclosure is certified IP66 and IP67. The standard heater consists of a single or multiple cartridge elements fitted into a mounting flange.
