Packard CH2552 Crankcase Heater - 120V 100W

The Packard CH2552 is a 120-volt, 100-watt crankcase heater designed to protect compressors in air conditioning and refrigeration systems. This essential component prevents refrigerant migration and oil dilution during compressor off-cycles by maintaining optimal crankcase temperature.

Key Features:

• 120V AC operation for standard electrical systems
• 100-watt heating element provides consistent warmth
• Prevents liquid refrigerant from condensing in compressor crankcase
• Reduces wear and extends compressor service life
• Helps ensure proper lubrication during startup
• Silicone rubber construction for durability and heat resistance
• Wraps around compressor body for direct heat transfer

Crankcase heaters are particularly important in HVAC systems operating in cold ambient conditions or with frequent on-off cycling. By keeping the oil warm and preventing refrigerant migration, this heater helps maintain proper viscosity and ensures adequate lubrication when the compressor starts, reducing the risk of mechanical damage and premature failure.
