Description
The standard heater consists of a single element or multiple cartridges fitted into a mounting flange. A robust Ex d terminal enclosure protects the electrical connections. The watts density of the element fitted depends upon the media to be heated and the kilowatt rating required.
The FP removable cartridge-type immersion heater range is certified for use in hazardous areas where the atmosphere is classified as a Zone 1 or 2 (IIA, IIB, IIC) gas group, or a Zone 21 or 22 (IIIA, IIIB, IIIC) dust group.
Features
- Certified to ATEX and IECEx standards
- Mild steel or 316 stainless steel terminal enclosure with weatherproof protection to IP66 or Enclosure Type / NEMA 4 or 4X
- Choice of built in process temperature sensors
- Suitable for ambient temperatures from -60°C to +60°C (subject to certification parameters)
- Mounting of the heater can be by a threaded NPT or BSP boss or an industry standard flange
- Designed for horizontal installation (vertical mounting version available on request)
- Can be supplied with the terminal box mounted away from the fixing boss / flange for high process temperatures
