Copeland ZR57K3E-TFD-950 Compressor

The Copeland ZR57K3E-TFD-950 is a high-efficiency scroll compressor engineered for commercial air conditioning and heat pump applications. Standardized for 460V 3-phase systems, this 5-ton unit delivers a nominal 57,000 BTU/hr capacity and is optimized for R-22 and R-407C refrigerant retrofits. Its hermetic design incorporates a 7/8” ODF suction and 1/2” ODF discharge connection, ensuring a secure fit and reliable thermal management under high-load conditions. Built with internal inherent motor protection, the ZR57K3E-TFD-950 prevents winding overheating during common commercial cycles. As a veteran in transition projects, this Copeland scroll compressor often replaces older reciprocating units due to its superior liquid handling capabilities and lower vibration levels. When installing, always verify the Polyol Ester (POE) oil charge is compatible with your current system piping to maintain proper lubrication and prevent premature bearing wear. This service model is the industry standard for maintaining uptime in critical light commercial HVACR infrastructure.

• Multi-Refrigerant Compatibility: Engineered for seamless operation with R-22, R-407C, and R-134a, making it a versatile choice for system upgrades.
• Advanced Scroll Technology: Provides a continuous compression process with fewer moving parts than reciprocating models, reducing mechanical failure points.
• Internal Motor Protection: Features internal line break protection to guard against over-current and high-temperature scenarios.
• Quiet Operation: Designed with smooth scroll movement and a sound shell that minimizes decibel levels in rooftop or ground-mount installs.

Is the ZR57K3E-TFD-950 a direct replacement for the ZR57K3-TFD-950?
Yes, the "E" in the model number designates the use of Polyol Ester (POE) oil, making it suitable for both R-22 and R-407C. It serves as the standard service replacement for the older mineral oil-based models.

Does this unit come with a pre-charged oil level?
Yes, it is factory-charged with POE oil. However, always check the system requirements during a retrofit, as R-407C conversions may require additional oil management or a complete flush of residual mineral oil.

What are the electrical requirements for installation?
This is a 460V, 3-phase, 60Hz unit. Technicians must verify phase rotation upon startup to ensure the scroll sets are not running in reverse, which can lead to lack of compression and potential damage.
