Daikin-McQuay 333613201 Belt Type Crankcase Heater 120V 120W 11″ Dia

The Daikin-McQuay 333613201 is a belt-type crankcase heater engineered to protect refrigerant compressors from oil dilution and slugging during cold-ambient startup conditions. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from migrating into and mixing with the compressor oil — a leading cause of premature compressor failure.

Key Features

• Belt-type design wraps securely around the compressor crankcase for efficient, even heat transfer
• 11-inch diameter sizing engineered for compatible Daikin-McQuay compressor applications
• 120-volt operating voltage for standard single-phase power supply compatibility
• 120-watt output delivers consistent, reliable heating to maintain proper oil viscosity
• Genuine Daikin-McQuay OEM replacement part (SKU 333613201) ensures proper fit and performance
• Helps extend compressor service life by preventing refrigerant migration during off cycles
