Hazardous Area

Compact Enclosure Heaters

ATEX Certified

EXHEAT FX hazardous area compact enclosure heaters provide flameproof heating and air warming for Zone 1 & Zone 2 (Flammable Gas) and Zone 21 & Zone 22 (Dust) hazardous areas and explosive atmospheres according to ATEX Directive.

The EXHEAT FX range of flameproof finned extruded enclosure heaters is designed specifically for frost protection, anti-condensation and temperature control.

FX enclosure heaters utilise a hard anodised, extruded aluminium profile, making them suitable for offshore applications, and include a fixed duty, cartridge type heating element in order to provide a powerful heating solution for small and medium sized enclosures.

The FX enclosure heaters can also be easily integrated with the FXT range of thermostats for enhanced temperature management. The FX enclosure heaters are available as fixed duty (FXB-FD and FXH-FD) and self-regulating (FXB-SR and FXH-SR).

FXB-FD AND FXH-FD FIXED DUTY

FLAMEPROOF ENCLOSURE HEATERS

Fixed duty heating elements produce a constant power output regardless of the ambient temperature, giving a specific temperature rise above the ambient.

FX fixed duty enclosure heaters have been certified to operate in an ambient temperature range of -60^°C to +40^°C for T4 and T3 heaters, and -60^°C to +80^°C for some T3 heaters.

The FXB-FD heaters are designed with a double-sided finned profile which may only be installed vertically to provide the greatest power output within the range. These heaters are supplied with a single mounting solution that can be used to affix the heater either directly to an enclosure or to a rail within one.

The FXH-FD heaters have one flat side which can allow flexibility, they can be mounted horizontally or vertically to suit possible space constraints.

Ambient	-60^°C with options up to +80^°C
Cabling	3m standard (up to 10m available on request)
IP Rating	IP66 / IP68
Mounting	FXB-FD: Wall or rail mounted vertically using the supplied mounting kit FXH-FD: Directly bolted to the enclosure or a bracket (not supplied)

EXHEAT FXH-FD

FXB-SR AND FXH-SR SELF-REGULATING

FLAMEPROOF ENCLOSURE HEATERS

Self-regulating heating elements produce a variable power output based on the ambient temperature, which removes the necessity of an additional thermostat.

FX self-regulating enclosure heaters have been certified to operate in an ambient temperature range of -60^°C to +180^°C for T3 applications and -60^°C to +130^°C for T4 applications.

The FXB-SR heaters are designed with a double-sided finned profile, but unlike the fixed duty heaters, may be installed in any orientation (although vertically will provide the greatest power output). These heaters are supplied with a single mounting solution that can be used to affix the heater either directly to an enclosure or to a rail within one.

The FXH-SR heaters have one flat side which can allow flexibility, they can be mounted in any orientation and directly to components that require heating
