The heaters are mainly used for compressors in heat pumps and air-conditioning or chiller systems that are installed in cold enviroments outdoors or in freezing rooms. The CCH heats the oil in the crankcase to prevent refrigerant migration and mixing with crankcase oil when the unit is off. It also prevents condensation of refrigerant in the crankcase and damage of the compressor. Backer patented design with omega style profile in aluminium permits the heat cable to rest directly on the compressor housing to achieve optimal heat properties with reduced energyconsumption along with installer-friendly features.
