‘HEF’ Hazardous Area Anti Condensation & Space Heaters
The self-regulating properties of the HEF enclosure heaters eliminate the requirement for a thermostat. Coupled with the compact design, this makes the HEF ideal for anti condensation, frost protection and temperature control where the enclosure is located within Zone 1 and Zone 2 or Class I, Div 2 Hazardous Areas.
Certified to ATEX Directive 94/9/EC IECEx requirements, they are suitable for use where the flammable atmosphere is Group IIA, IIB or IIC Gas.
