Copeland 918-0118-05 Crankcase Heater
The Copeland 918-0118-05 Crankcase Heater is a field-proven solution for protecting compressors against refrigerant migration and liquid slugging during off-cycles. As a 120V 50W bolt-on heater, it provides consistent thermal energy to the compressor oil, ensuring it remains fluid and at the correct viscosity for immediate lubrication upon startup. This external heating element is specifically engineered for compatibility with Copeland Discus and Emerson H and K series compressors, where maintaining a temperature differential between the crankcase and the evaporator is critical for system longevity. The bolt-on design allows for a secure, high-contact fit, maximizing heat transfer efficiency compared to standard wrap-around alternatives. By utilizing this OEM replacement part, technicians can effectively prevent oil carbonization and ensure reliable operation in low-ambient conditions. Its 50-watt power output is precisely calibrated to provide sufficient warmth without overheating the lubricant, making it a staple for refrigeration and HVAC compressor maintenance.
Key Benefits
- Ensures lubrication reliability by preventing refrigerant from condensing in the compressor oil.
- Facilitates a high-contact thermal bond via its external bolt-on configuration for superior heat conduction.
- Reduces mechanical stress by eliminating liquid slugging during cold-weather startups.
- Optimized for Emerson refrigeration systems, providing a direct fit for H, K, and Discus models.
- Rugged construction designed for the high-vibration environment of a commercial compressor.
Common Questions
How do I install the Copeland 918-0118-05?
This is an external bolt-on type heater. It should be fastened directly to the compressor base or specified mounting point to ensure maximum surface contact for heat transfer.
What happens if a crankcase heater fails?
Failure to maintain crankcase heat leads to refrigerant migration, which dilutes the oil. This often results in bearing failure or broken reed valves due to liquid compression at start-up.
Is 50 watts sufficient for outdoor rooftop units?
Yes, the 50W output is the standard specification for these compressor frames to keep oil fluid without causing thermal degradation or carbonizing the lubricant.
