Description
AAON P83890 Belt Type Crankcase Heater
The AAON P83890 is a belt-type crankcase heater engineered to protect refrigeration compressors from the damaging effects of refrigerant migration and liquid slugging. By maintaining the compressor crankcase at an elevated temperature during off-cycle periods, this heater prevents refrigerant from condensing and mixing with compressor oil — a leading cause of premature compressor failure.
