Description: The EXHEAT® ‘RFA-C’ range of flameproof removable core heaters offers a Hazardous Area heating solution for oil and similar applications where low heat density is required. The element can be withdrawn for inspection without system drain down. The standard heater consists of a single element core fitted into a mounting flange. 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.
Certified Ex II 2 G to meet the ATEX Directive 94/9/EC.
Lightweight cast aluminium alloy terminal enclosure with weatherproof protection to IP66 and IP67.
Choice of built in process temperature sensors.
Suitable for ambient temperatures down to -50°C.
Mounting of the heater can be by threaded boss or an industry standard flange.
Designed for horizontal installation only. Vertical mounting version available on request.
Can be supplied with the terminal box mounted away from the fixing boss/flange for high process temperatures.
