Description
The Copeland 918-0038-02 is a 240-volt, 45-watt wrap-around crankcase heater engineered to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration and liquid slugging during off-cycle and low-ambient conditions.
How It Works
Wrap-around crankcase heaters maintain the compressor oil temperature above the saturation temperature of the refrigerant, preventing liquid refrigerant from mixing with the compressor oil. This is especially critical during extended off-cycles, cold-weather startups, and low-ambient operation where refrigerant tends to migrate to the crankcase.
Key Features
- Operating Voltage: 240V
- Wattage: 45W
- Wrap-around design for secure, full-contact fit on compressor body
- Prevents refrigerant migration into compressor oil during off-cycles
- Protects against liquid slugging and compressor damage on startup
- OEM Copeland replacement part — direct-fit compatibility
- Durable construction for long service life in demanding HVAC/R environments
Application
Designed as a genuine Copeland OEM replacement, the 918-0038-02 is ideal for use on Copeland compressors in residential and light commercial air conditioning, refrigeration, and heat pump systems. Always verify compressor model compatibility before installation.
Why Use a Crankcase Heater?
Skipping or neglecting a crankcase heater can lead to compressor failure caused by oil dilution and liquid refrigerant slugging — one of the most common and costly causes of compressor damage. Installing the correct crankcase heater is a low-cost measure that significantly extends compressor life and reduces service callbacks.
