Description
The Copeland 918-0028-11 is a genuine OEM crankcase heater 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 compressor oil, reducing the risk of compressor damage on startup and extending overall equipment service life.
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 can cause slugging, bearing wear, and premature failure. The crankcase heater continuously warms the oil sump, keeping refrigerant in its vapor state and ensuring proper lubrication is available at every startup.
