Description
The International Comfort Products NASA003CH is a belt-type crankcase heater engineered to protect refrigerant compressors from refrigerant migration and oil dilution during off-cycle periods. By maintaining a consistent warmth around the compressor crankcase, this heater helps prevent liquid refrigerant from mixing with compressor oil — a leading cause of compressor failure on startup.

Why Use a Crankcase Heater?
During extended shutdown periods, refrigerant can migrate into the compressor crankcase and mix with the lubricating oil. When the compressor restarts, this diluted oil can cause inadequate lubrication, leading to premature wear or catastrophic failure. Installing a crankcase heater is a proven preventive measure that keeps the oil warm and refrigerant-free, safeguarding your investment.
