Copeland 918-0019-01 Crankcase Heater

The Copeland 918-0019-01 is a high-performance belt-type crankcase heater designed to maintain critical oil temperatures in refrigeration and AC compressors. Operating at 120V and delivering 70W of heating power, this component prevents refrigerant migration to the crankcase during the off-cycle, significantly reducing the risk of slugging and mechanical failure upon startup. Engineered for durability, this external wrap-around heater ensures optimal lubricant viscosity, even in low ambient conditions. This OEM Copeland heater provides a precise fit for various scroll and reciprocating compressors, making it a reliable choice for field replacements or new installations. Contractors rely on this crankcase heater 70W 120V to extend service life and improve system reliability by keeping the compressor housing warmer than the coldest part of the system. Proper installation of this compressor belly band heater is essential for preventing liquid dilution of the oil.

Key Benefits

• Prevents Liquid Slugging: Maintains oil temperature to ensure refrigerant remains in a vapor state within the crankcase.
• Consistent Heat Distribution: The 70-watt output provides uniform thermal transfer across the compressor housing.
• Rugged Belt Design: Flexible wrap-around architecture allows for a secure, contact-tight fit on specific compressor diameters.
• OEM Compatibility: Specifically designed to meet factory specifications for Copeland compressor parts.

Common Questions

How do I verify if this heater fits my specific compressor?
Confirm your compressor model number and diameter. This 120V belt-type heater is sized for specific Copeland frames; checking the physical circumference and voltage is required before installation.

Does this heater run continuously?
Standard field practice involves wiring the heater to be energized during the compressor's off-cycle, often through a normally closed contact on the system's contactor.

What happens if the heater fails?
Failure to maintain crankcase heat can lead to oil foaming and bearing washout during startup, which can result in catastrophic compressor failure.
