Description
Packard CH101340 Crankcase Heater Overview
The Packard CH101340 is a 480-volt, 54-watt crankcase heater engineered to protect refrigeration and air conditioning compressors from refrigerant migration and oil dilution during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from mixing with compressor oil — a leading cause of premature compressor failure, slugging, and bearing damage.
Key Features
- 480V operating voltage for compatibility with commercial and industrial HVAC/R systems
- 54W wattage provides consistent, efficient crankcase warming
- Designed to prevent refrigerant migration into compressor oil during off cycles
- Helps extend compressor service life and reduce costly compressor replacements
- Easy wrap-around or belly-band installation on compressor crankcase
- Packard quality construction for reliable, long-term performance
Why Use a Crankcase Heater?
During compressor off cycles — especially in cold ambient conditions — refrigerant can migrate to the crankcase and dissolve into the compressor oil. When the compressor restarts, this refrigerant flashes off rapidly, causing oil foaming, loss of lubrication, and potential compressor damage. The Packard CH101340 crankcase heater energizes during off cycles to keep the crankcase warm, preventing refrigerant absorption and ensuring a safe, lubricated startup every time.
