Electrical Heating Products For Explosive Atmospheres
30W to 500W
The HEF range of hazardous area heaters manufactured by EXHEAT are self-regulating, automatically adjusting its output to match ambient temperatures – the EXHEAT HEF range of electric heaters are ATEX Certified & Approved and suitable for ambient temperatures from -60°C (-55°C for CSA certified models only) to +80°C. The EXHEAT HEF range of enclosure heaters can be mounted in any orientation.
This range of electrical heating products are certified for use in hazardous areas where the potentially explosive atmosphere is classified as a Zone 1 or Zone 2 (IIA, IIB, IIC) gas group according to ATEX.
HEF heaters are self-regulating, automatically reducing its output as the ambient temperature rises. If overall enclosure temperature control is required, it is recommended that the HEF heater be used in conjunction with the AFT, HFT or FXT flameproof air sensing thermostats in hazardous areas industries and applications including onshore and offshore, battery stores, paint/solvent workshops and spraybooths, enclosures and cabinets and frost protection.
EXHEAT HEF enclosure heaters provide frost protection and air heating to prevent equipment breakdowns due to freezing condensation – this ensures the continuous operation of delicate instrumentation in enclosures and maintaining room ambient temperatures at safe working levels.

Please download EXHEAT HEF hazardous area enclosure heaters O&M manual for full details on installation and maintenance procedures – this includes wiring diagrams, earth connection and pre installation inspection and checks.
The EXHEAT HEF must be installed according to IEC / EN 60079-14 and should be securely fixed in position and all connections checked before energising.
The HEF is designed for use inside an enclosure as the supply cable is unsuitable for use outside and must be protected by the enclosure to reduce the risk of damage.
These enclosure heaters are suitable for Zone 1 & Zone 2 (IIA, IIB, IIC) gas groups according to ATEX | IECEx Directive and Class I, Division 2 (Groups A, B, C, D).
