Copeland 918-0043-07 Belt Type Crankcase Heater Overview
The Copeland 918-0043-07 is a belt-type crankcase heater engineered to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration. By maintaining the crankcase oil at an elevated temperature during off-cycles, this heater prevents liquid refrigerant from mixing with compressor oil — a leading cause of compressor failure and premature wear.
Key Features
- Belt-type design wraps securely around the compressor crankcase for maximum heat transfer
- Operating voltage: 120 Volts
- Wattage: 70 Watts
- Genuine Copeland OEM replacement part (SKU: 918-0043-07)
- Helps prevent refrigerant migration into compressor oil during off-cycles
- Extends compressor service life and reduces risk of liquid slugging
- Flexible belt construction conforms to crankcase contours for consistent, even heating
Why Use a Crankcase Heater?
During compressor shutdown, refrigerant can migrate into the crankcase and dissolve into the lubricating oil. When the compressor restarts, this refrigerant rapidly boils off, causing oil foaming and potentially catastrophic bearing and valve damage. A crankcase heater keeps the oil warm enough to discourage refrigerant absorption, ensuring reliable startups and long compressor life.
Application
- Compatible with select Copeland compressor models — verify fit against your compressor model number before ordering
- Suitable for commercial refrigeration and air conditioning systems
- Ideal for installations in low-ambient or cold-climate environments where refrigerant migration risk is elevated
