The HEF is self-regulating, automatically adjusting its output to match ambient temperatures. Coupled with its compact design, this makes the HEF ideal for anti-condensation, frost protection and temperature control for all instrumentation and switch gear applications. The HEF range is certified for use in hazardous areas where the atmosphere is classified as a Zone 1 or 2 (IIC) gas group.
