Copeland 918-0097-01 Crankcase Heater

The Copeland 918-0097-01 Crankcase Heater is a critical OEM replacement part designed to protect HVACR compressors from the damaging effects of liquid refrigerant migration. Built for 240-volt electrical systems, this 40-watt belt-type heater maintains optimal crankcase temperatures during off-cycles to prevent oil dilution and ensures the lubricant retains its proper viscosity. Featuring a 5-inch diameter and 30-inch leads, this wrap-around heater is engineered for a secure fit on standard compressor housings, providing uniform heat distribution to avoid carbonization of the oil while mitigating the risk of flooded starts.

For technicians servicing commercial refrigeration or residential air conditioning units, the Copeland 918-0097-01 is a standard solution to extend compressor longevity in low-ambient conditions. Its durable construction is designed to withstand the thermal expansion and contraction cycles common in outdoor condensing units. By keeping the refrigerant in a vapor state within the crankcase, this heater prevents liquid slugging at startup, a leading cause of catastrophic valve failure and mechanical wear. This crankcase heater kit is a professional-grade component essential for any preventative maintenance schedule involving Copeland compressors.

• Prevents Refrigerant Migration: Keeps refrigerant from condensing in the oil during system downtime, ensuring reliable lubrication.
• Optimized Wattage: The 40W output is calibrated to provide sufficient warmth without overheating or degrading the compressor oil.
• Simple Installation: The 5" belt-type design and 30" lead wires allow for easy mounting and flexible wiring into existing control circuits.
• Universal Applicability: Standard 240V operation makes it compatible with a wide range of industrial and commercial HVACR equipment.

How do I confirm if this heater is wide enough for my compressor?
This model is designed with a 5-inch diameter and a flexible belly band wrap-around style, typically fitting scroll compressors and small reciprocating models in that size range. Always verify the circumference of your compressor shell against the 5-inch diameter specification.

Why do I need to replace a failed crankcase heater even in warmer climates?
Refrigerant migration depends on pressure differentials. Even in mild temperatures, if the compressor becomes the coolest part of the system during the off-cycle, refrigerant will condense in the oil, leading to liquid slugging upon startup.

Should this heater remain energized while the compressor is running?
Ideally, the heater should be wired through an auxiliary contact on the contactor so it is energized only during the "off" cycle. This prevents unnecessary energy consumption and adds life to the heating element.
