Copeland 918-0038-02 Heater
The Copeland 918-0038-02 is a professional-grade 240V 45W Wrap-Around Crankcase Heater engineered to maintain critical oil temperature in high-pressure refrigeration compressors. During the off-cycle, refrigerant naturally migrates to the coldest part of the system—the compressor crankcase. This heater prevents refrigerant from condensing into the oil, effectively eliminating liquid slugging and ensuring proper lubrication at startup. Designed with a flexible bellyband configuration, it provides uniform thermal distribution across the compressor housing, making it a reliable solution for outdoor condensing units and rooftop applications exposed to low ambient temperatures.
This 45-watt element is specifically sized for Copeland and Emerson scroll platforms, including the AFJ series, to provide sufficient heat without risking oil carbonization. For technicians, the 48.25-inch lead length allows for clean routing into the control box for landing on the contactor (L1/L2) or an auxiliary switch. Utilizing an OEM crankcase heater like the 918-0038-02 ensures the exact resistance profile required for 240V circuits, maintaining system efficiency and protecting the mechanical integrity of the scroll sets during the most demanding cold-weather starts.
Key Benefits
- Prevents Liquid Slugging: Maintains oil temperature above the refrigerant saturation point to keep liquid out of the cylinders.
- Uniform Heat Transfer: The wrap-around design ensures consistent thermal contact with the compressor shell, preventing cold spots.
- Optimized Wattage: The 45W/48W output is calibrated to protect oil viscosity without causing thermal breakdown or overheating.
- OEM Compatibility: Matches factory specifications for Copeland compressor parts, ensuring correct fitment and electrical draw.
- Extended Equipment Life: Reduces mechanical stress during startup by ensuring bearings are lubricated with pure oil rather than a diluted refrigerant-oil mixture.
Common Questions
- How do I test if the heater is functioning? Disconnect power and measure resistance across the leads with a multimeter. A reading of "OL" indicates a broken element that requires immediate replacement.
- When should the heater be energized? It must be wired to operate during the compressor off-cycle. Systems that have been powered down for extended periods should have the heater energized for at least 24 hours before startup.
- Which compressors does this fit? It is primarily designed for Copeland scroll compressors and specific refrigeration models like the AFJ1 and AFJ23; always verify shell diameter for proper tension.
