Crankcase Heater for HVAC Compressors

Prevent refrigerant from migrating and condensing, commonly referred to as slugging, in the compressor of your air conditioner or heat pump when running your unit on cool days. These heaters keep crankcase oil warm to boil off any absorbed refrigerant before it mixes with the oil and migrates to the condenser, where it may damage your compressor and other components.
