EXHEAT FP 4 specification

The FP 4 rod-type immersion heater is certified for use in hazardous areas where the explosive 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.

Enclosure: Mild steel or 316 stainless steel, external and internal earths, screwed terminal cover, finished in epoxy paint if required
Elements: A choice of rod-type elements comprising of 80/20 nickel chrome resistance wire, compacted in high purity magnesium oxide insulating powder and encased in either Incoloy or stainless steel sheath, secured by
compression fittings, brazing or welding, depending upon the process application
Controls: Heater over-temperature protection is fitted as standard (optional process temperature sensing devices can be incorporated in the form of thermostats, RTD’s or thermocouples)
Mounting: Any threaded NPT or BSP boss, or flange in any material, can be specified within the limits of the design parameters; heater terminal box can be either ‘direct-on’ or ‘stand-off’, depending on process temperature
Rating: To suit process requirements within the design and certification parameters
Voltage: Any electrical supply up to 690V (600V CSA)
