Description
The Copeland 918-0097-00 is a genuine OEM crankcase heater kit designed to protect Copeland 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 accumulating in the oil sump — a leading cause of compressor damage and premature failure.
How It Works
During system shutdown, refrigerant can migrate to the compressor crankcase and mix with the lubricating oil. When the compressor restarts, this diluted oil fails to provide adequate lubrication, leading to bearing wear and potential compressor failure. The crankcase heater keeps the oil temperature above the refrigerant condensing point, ensuring refrigerant remains in the vapor state and oil viscosity is maintained at startup.
