Small semiconductor Heater HGK047 Series 10W to 30W • Dynamic heating up • Energy saving • Wide voltage range • Clip fixing The heaters are used in enclosures where condesation is to be prevented or the temperature may not fall below a minimum value.In this way corrosion is avoided and an even temperature is ensured. The heaters are designed for permanent operation.
