Description
Copeland 918-0047-03 Crankcase Heater Overview
The Copeland 918-0047-03 is a 575-volt, 90-watt crankcase heater engineered to protect refrigeration and air conditioning compressors from refrigerant migration during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor damage and premature failure.
Key Features
- OEM Copeland replacement crankcase heater for precise fit and reliable performance
- Operating voltage: 575V
- Power rating: 90 Watts
- Prevents refrigerant migration into compressor oil during off-cycle periods
- Helps extend compressor service life and reduce costly downtime
- Direct OEM replacement ensures compatibility with applicable Copeland compressor models
Why Crankcase Heaters Matter
During extended off cycles — especially in cold ambient conditions — refrigerant can migrate into the compressor crankcase and dilute the lubricating oil. When the compressor starts, this refrigerant-oil mixture can cause slugging, bearing wear, and catastrophic compressor failure. A properly functioning crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free.
Application
- Commercial refrigeration systems
- Air conditioning compressors
- Systems operating in low ambient temperature environments
- Replacement for worn or failed OEM crankcase heaters on compatible Copeland compressors
