Copeland 918-0009-01 Crankcase Heater

For field technicians and mechanical contractors maintaining critical refrigeration systems, the Copeland 918-0009-01 Crankcase Heater is an essential OEM component designed to mitigate refrigerant migration during off-cycles. This 240V 65W bolt-on heater is specifically engineered for semi-hermetic compressors, including 3A, 3R, E, L, M, and N series models, excluding deep sump variants. Utilizing a 10-inch diameter body, it provides consistent thermal contact to the compressor housing, ensuring oil remains at the proper viscosity to prevent washed-out bearings and liquid slugging upon startup. This kit features a 23-inch conduit length and 30-inch leads, providing ample reach for secure wiring within the junction box. When selecting a replacement crankcase heater, verifying the wattage and voltage compatibility is paramount to avoid electrical mismatch. The robust bolt-on design ensures a durable mechanical connection that withstands the high-vibration environments typical of commercial HVACR applications, ensuring optimal compressor performance and system reliability.

• Prevents Refrigerant Migration: Maintains crankcase temperature above the system's dew point to keep refrigerant from mixing with the oil.
• OEM Compatibility: Precision-fit for Copeland Copelametic and Discus compressors, ensuring a reliable compressor heater installation.
• Durable Construction: Features a rugged 23-inch conduit and high-temperature 30-inch leads for long-term service in demanding environments.
• Easy Mechanical Attachment: The bolt-on design allows for direct-to-case mounting, providing superior heat transfer compared to wrap-around alternatives.

• How do I confirm if this heater fits my specific compressor? Check your compressor model prefix; this unit is designed for 3A, 3R, E, L, M, and N series. Avoid use on deep sump models.
• Can I use a 240V heater on a 208V system? While it will operate, the heat output (wattage) will be significantly reduced. For peak performance, match the voltage to your system's power supply.
• Why is a bolt-on heater preferred over a wrap-around style? Bolt-on heaters offer a more permanent and thermally efficient connection, which is critical for larger semi-hermetic units.
