Immersion heater | ATEX gas zones | FP type

The FP electric immersion heater is ATEX-certified for use in Zone 1, 2, 21 and 22 of explosive gas or liquid vapour atmospheres. The standard versions of the product can be supplied with any electrical power source with voltage up to 690 V (600 V CSA). Each heater is provided with a terminal box for easy wiring and the overall design allows fast installation in the processing system (with a NPT/BSP threaded end or a standard connection flange).

The heater is designed for long, heavy-duty operation. The heating element is a high-quality, NiCr (80/20) resistance conductor. It is installed in a sheath of Incoloy 800 (or, optionally, stainless steel) filled with magnesium oxide powder which provides electrical insulation and an extremely good heat transfer coefficient.

The enclosure of the heater is made of mild steel (or, optionally, stainless steel) finished by powered coating (or, optionally, epoxy coating). This series of heaters is intended for various types of process media flowing in horizontal piping (there are optional heaters available for vertical installation orientation) and various types of processing equipment units.

The product is supplied with a plugged 20 mm cable gland. More cable glands can be provided on request. The standard version features overtemperature protection.

The permitted ambient operating temperature of the heaters ranges from -60˚C to +60˚C.
