‘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 Hazardous Areas. Certified to ATEX Directive 94/9/EC IECEx, they are suitable for use where the flammable atmosphere is Group IIA, IIB or IIC Gas. FEATURES Certified to meet the requirements of the ATEX Directive 94/9/EC IECEx Compact, low profile, stainless steel case, requires minimal space Self-regulating - can be used without a thermostat Suitable for ambient temperatures from -60°C to +80°C Mounting of the heater can be in any orientation Design allows installation close to internal components and cables without fear of damage by overheating TYPICAL APPLICATIONS Control / monitoring panels Instrumentation cabinets Condensation prevention Temperature fluctuations Frost protection
