Crankcase Heaters

(541 Products)

HVAC Depot carries hundreds of name brand crankcase heaters for OEM and aftermarket replacement. Crankcase heaters prevent refrigerant from mixing with crankcase oil when the compressor unit is off. It is also used to prevent condensation of refrigerant in the compressor crankcase by keeping the refrigerant temperature higher than the coldest part of the system.
