Copeland 918-0047-01 Heater

The Copeland 918-0047-01 is a high-performance crankcase heater engineered to protect compressor longevity by maintaining optimal oil temperature during off-cycles. Operating at 240V with a 90-watt output, this external wrap-around heater utilizes a rugged heating element to prevent refrigerant migration and subsequent liquid slugging at startup. It is specifically designed for Copeland Scroll compressors, including ZB, ZP, ZR, and ZPT series models such as the ZR84K through ZR144K. The 48-inch lead length provides flexibility for the HVAC technician during field installation on large-tonnage commercial air conditioning and refrigeration units. By keeping the lubricant fluid even in low ambient temperatures, this 918-0047-01 heater ensures reliable compressor startup and efficient oil circulation, mitigating the risk of carbonizing oil or mechanical bearing failure. This component is a direct replacement for legacy part numbers 018-0007-02 and 018-0047-02, facilitating a professional, drop-in fit for industrial service requirements.

• Optimized Heat Distribution: Delivering a consistent 90W to the crankcase base, ensuring the oil remains above the refrigerant saturation point.
• Broad Compatibility: Fits an extensive range of Copeland Scroll models, including ZB50K-ZB88K, ZP120K, and ZRT series.
• Rugged Build Quality: Constructed with high-grade materials to withstand the vibration and thermal cycling of commercial HVACR applications.
• Reduced Maintenance Costs: Significantly lowers the risk of liquid slugging, which is the primary cause of premature compressor replacement.

• Is this heater compatible with 120V systems? No, this is a 240V dedicated component; verify your control circuit voltage before installation.
• What lead length comes with this 918-0047-01? This model features a standard 48-inch lead length, suitable for most large-frame compressor housings.
• Can this be used on semi-hermetic compressors? This specific model is designed as a wrap-around heater for scroll compressors; contact us for bolt-on or immersion heaters for Discus or Copelametic models.
