Copeland 918-0056-05 Crankcase Heater
Maintain peak compressor reliability during the off-cycle with the Copeland 918-0056-05 Crankcase Heater. This 480V 120W belt type heater is engineered specifically for Copeland ZR250 compressors and high-tonnage industrial refrigeration systems. In low ambient conditions, refrigerant naturally migrates to the coldest part of the circuit—the compressor oil. Without a functional belly band heater, this results in flooded starts, oil dilution, and catastrophic slugging. By delivering a consistent 120 watts of thermal energy, this OEM Copeland replacement part ensures the lubricant remains at a temperature above the refrigerant's saturation point, preserving proper viscosity and system efficiency. The wrap-around design provides maximum surface contact with the compressor shell for rapid heat transfer. For commercial technicians, replacing a failed crankcase heater strip during preventative maintenance is the standard procedure to prevent costly mechanical failure and downtime in high-voltage 480V applications. Ensure your HVAC compressor protection is active to avoid tripped breakers and liquid-rich foam at startup.
Key Benefits
- Prevents Refrigerant Migration: Stops liquid refrigerant from condensing in the oil during idle periods, eliminating flooded starts.
- Optimized Compressor Lifespan: Maintains lubricant integrity to ensure immediate bearing lubrication upon system engagement.
- Direct Fit OEM Quality: Specifically designed as a 918-0056-05 replacement for a secure, high-contact fit on large-diameter shells.
- High-Efficiency Heat Transfer: The 120W output is calibrated for 480V industrial circuits to provide reliable warming in sub-freezing temperatures.
Common Questions
How do I know if my 480V crankcase heater has failed?
Technicians should check for continuity across the heater leads with a multimeter or measure for an amp draw while the compressor is in the off-cycle. A tripped breaker or cold compressor sump during the off-cycle often indicates a burnt-out element.
Can I use this 120W heater on a smaller compressor?
It is critical to match the wattage and band diameter to the specific compressor frame. This Copeland 918-0056-05 is sized for larger units like the ZR250; using an oversized heater can lead to excessive oil temperatures and carbonization.
Does this heater run while the compressor is operating?
Typically, crankcase heaters are wired through an auxiliary contact on the compressor contactor so they are energized only when the compressor is off. Continuous operation while the motor is running is unnecessary and reduces the service life of the heater.
