Description
AAON P72120 Belt Type Crankcase Heater
The AAON P72120 is a belt-type crankcase heater engineered to protect compressor integrity by preventing refrigerant migration into the compressor oil during off-cycle periods. Designed as a genuine AAON OEM replacement part, this heater ensures reliable, long-term performance in AAON rooftop and commercial HVAC equipment.
How It Works
The belt-type design wraps snugly around the compressor crankcase, delivering consistent, even heat across the surface. By maintaining crankcase temperature above the refrigerant condensation point, it prevents liquid refrigerant from diluting the lubricating oil — a leading cause of compressor wear and failure at startup.
