Description
Copeland 918-0002-01 Immersion Type Crankcase Heater Overview
The Copeland 918-0002-01 is an immersion-type crankcase heater engineered to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration during off-cycle periods. By maintaining the crankcase oil at an elevated temperature, this heater prevents liquid refrigerant from mixing with compressor lubricant — a leading cause of bearing wear, slugging, and premature compressor failure.
Key Features
- Immersion-type design for direct, efficient heat transfer to compressor oil
- Operating voltage: 480 Volts
- Wattage: 100 Watts
- Genuine Copeland OEM replacement part (SKU: 918-0002-01)
- Prevents refrigerant migration into crankcase oil during compressor off cycles
- Helps extend compressor service life and reduce maintenance costs
- Designed for reliable, continuous-duty operation
Application
This crankcase heater is designed for use with compatible Copeland compressors in commercial and residential HVAC and refrigeration systems. It is particularly important in installations where the compressor may be located in cold ambient environments or where extended off-cycle periods are expected. Always verify compatibility with your specific compressor model before installation.
Why Use a Crankcase Heater?
During compressor shutdown, refrigerant can migrate to the crankcase and dissolve into the oil. On startup, this refrigerant rapidly boils off, causing oil foaming and loss of lubrication. The Copeland 918-0002-01 immersion heater keeps the oil warm enough to prevent this migration, ensuring proper lubrication from the moment the compressor starts.
