Crankcase Heaters
The crankcase heater is a flexible resistive heating element that is embraced, inserted inside, or connected by some or other way to the compressor's crankcase of an air-conditioning system, heat pump system, or chiller system. The crankcase heater is normally on all the time, even when the unit is not running, though temperature sensors and set points may turn it off when not needed. The function of the crankcase heater is to prevent refrigerant migration and mixing with crankcase oil when the unit is off. Refrigerant entering the crankcase will then be vaporized and driven back into the suction line.
