Description
The Copeland 918-0052-03 Crankcase Heater is an indispensable component of air conditioning systems. It prevents refrigeration vaporization by holding on to evaporated oil within the heater, with an insulated electrical coil helping in that function. Temperature regulation in the crankcase reduces the chance that there will be liquid slugging at start-up, which causes system loss of efficiency and damage. The crankcase heater is especially essential in cold regions since it allows operating even at low ambient temperatures to provide lubrication for compressors crankshafts.
