Copeland CR42K6E-TFD-875 Compressor

The Copeland CR42K6E-TFD-875 is a high-efficiency 460V 3-phase air conditioning compressor engineered for commercial and light industrial HVAC systems. Delivering a nominal capacity of 41,700 BTU, this hermetic reciprocating model is optimized for R-407C and R-22 applications, utilizing POE oil for superior lubrication and reliability in high-ambient conditions. As a direct replacement for the CR41KQ-TFD-267RM and P021-4272, it features an industry-standard 7.5" x 7.5" mounting footprint, ensuring a seamless drop-in fit for technicians servicing 3.5-ton units. Professional installation requires verifying the suction and discharge line sizes to match the 7/8" x 1/2" stub-type connections. This hermetic compressor is built to handle heavy cycling while maintaining a low sound profile, making it a reliable choice for critical cooling infrastructure where performance consistency is non-negotiable.

• Broad Compatibility: Serves as a direct technical cross for S1-H22J443DBEA, 060604202, and AV145TT-036-J7, reducing downtime during field replacements.
• Engineered Durability: Robust internal components designed to withstand liquid slugging and high discharge temperatures in demanding service environments.
• Optimized Efficiency: Precision-machined reciprocating technology provides stable compression ratios and consistent lift across varied load profiles.
• Commercial Grade: Explicitly configured for 460-volt three-phase power systems, ensuring balanced electrical loads and lower amperage draw compared to single-phase alternatives.

Common Questions

What refrigerant oil is pre-charged in the CR42K6E-TFD-875?
This model comes pre-charged with Polyolester (POE) oil, making it compatible with HFC refrigerants like R-407C. When used as a retrofit for R-22 systems, ensure proper oil management and filter-drier replacement.

Is this compressor a direct drop-in for the CR42K6E-TFD-775?
Yes, the 875 nomenclature indicates specific bill of materials and packaging, but the physical dimensions, electrical requirements, and performance curves match the 775 and S1-015-04778-001 specifications.

What are the wiring requirements for this 3-phase model?
The TFD motor protection code requires a 460V power supply. Always verify phasing with a meter during startup to ensure proper rotation and avoid mechanical damage to the internal valve plates.
