Copeland ZF11K4E-TF5-931 Compressor

The Copeland ZF11K4E-TF5-931 Compressor is a 3.5 HP scroll compressor engineered specifically for low-temperature refrigeration and medium-temperature applications. Operating on 208-230V, 3-phase power, this unit delivers a nominal 11,700 BTU/hr capacity. Its design is optimized for high-duty cycles in commercial environments, featuring a 7.5" x 7.5" mounting pattern and standard sweat connections (3/4" suction and 1/2" discharge) to simplify field replacements and new installations.

This hermetic scroll compressor is pre-charged with Polyol Ester (POE) oil, allowing for broad refrigerant compatibility with modern HFCs and HFO blends including R-404A, R-448A, R-449A, R-507, and R-134a, as well as legacy R-22 systems. With a Rated Load Amperage (RLA) of 13.6/12.5, it provides stable performance under demanding head pressures. Technicians can rely on the ZF series for its ability to handle liquid slugs and high-debris environments more effectively than traditional reciprocating models.

Key Benefits:

• Enhanced Efficiency: The ZF refrigeration scroll design offers higher volumetric efficiency compared to reciprocating units.
• Multi-Refrigerant Capability: Supports R-404A, R-448A, and R-134a, reducing inventory requirements for diverse service trucks.
• Durable Construction: Built with internal pressure relief and high-temperature protection to ensure commercial refrigeration uptime.
• Standardized Footprint: The 16.1-inch height and standard mounting ensure compatibility with most condensing unit frames.
• Quiet Operation: Scroll technology significantly reduces vibration and noise levels compared to piston compressors.

Common Questions:

Is the ZF11K4E-TF5-931 compatible with R-448A and R-449A?
Yes, this model is fully rated for use with R-448A and R-449A, provided the system uses the standard POE oil already present in the compressor.

Does this compressor require liquid injection?
For low-temp applications where discharge temperatures may exceed safe limits, verify if your specific system configuration requires the addition of a DTC (Discharge Temperature Control) valve.

What is the primary difference between the ZF and ZS models?
The ZF series is specifically optimized for low-temperature envelopes, whereas ZS models are typically utilized for medium-temperature refrigeration and high-temp air conditioning applications.
