Copeland 918-0088-01 Heater

The Copeland 918-0088-01 is a high-voltage, wrap-around crankcase heater kit engineered for 480V/575V commercial and industrial applications. Designed specifically for bellyband heater mounting on CF and CS model compressors, this 40-57 watt heating element is a critical component for maintaining oil temperature during off-cycles. By keeping the sump temperature higher than the rest of the system, it effectively mitigates refrigerant migration, preventing liquid slugging and mechanical failure during cold starts. For technicians servicing rooftop or outdoor refrigeration units, the 918-0088-01 ensures that compressor lubricant remains at the correct viscosity, promoting immediate oil pressure development. This kit features a rugged, heavy-duty construction with a UL-recognized design, providing a reliable thermal interface for hermetic and semi-hermetic compressors. Proper positioning just below the compressor dimples and over the vertical weld seam is professional protocol to maximize heat transfer and protect the lead wires from damage.

Key Benefits

• Optimized Thermal Protection: Maintains 40-57 watts of heat to prevent liquid refrigerant migration into the oil sump during low ambient conditions.
• Broad Compatibility: Tailored for Copeland CF and CS compressors, ensuring a precise fit for the bellyband mounting system.
• High Voltage Performance: Designed specifically for 480/575 volt electrical circuits, eliminating the need for step-down transformers in industrial environments.
• System Reliability: Minimizes the risk of liquid slugging, which is the leading cause of premature compressor valve and bearing failure.
• Direct OEM Replacement: Replaces Emerson 918-0088-01 components with industrial-grade materials for long-term field durability.

Common Questions

Where should the 918-0088-01 bellyband heater be positioned on the compressor?
Technicians should install the heater below the compressor housing dimples. It is critical to position the bellyband screw directly over the vertical weld seam to prevent wire damage and ensure consistent thermal contact.

How does this heater prevent compressor failure?
By maintaining a consistent temperature in the crankcase, the heater resists the tendency of refrigerant vapor to condense in the oil. This prevents "foaming" and ensures the oil pump delivers pure lubricant rather than a refrigerant-rich mixture at startup.

Is this part suitable for 208/230V systems?
No, this specific model is rated for 480/575V power supplies. Using this on lower voltage systems will result in insufficient heat output, failing to protect the compressor from migration.
