Description
The Copeland 918-0056-04 is a belt-type crankcase heater engineered to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration and liquid slugging during off-cycle periods. By maintaining the crankcase oil at a temperature above the surrounding ambient, this heater prevents refrigerant from condensing into the compressor oil — a leading cause of compressor failure and premature wear.
Product Overview
Designed as a direct Copeland OEM replacement, the 918-0056-04 wraps securely around the compressor crankcase, delivering consistent, even heat distribution. Its belt-style design ensures reliable contact and efficient heat transfer across the compressor body.
