Copeland ZF18K4E-TF5-961 Compressor
The Copeland ZF18K4E-TF5-961 is a high-performance low temperature scroll compressor engineered for demanding commercial refrigeration applications. Rated at 6 HP and 18,200 - 19,500 BTU, this 208/230V 3-phase compressor is built to handle multiple refrigerants including R-22, R-404A, and R-448A/449A. As a veteran-grade refrigeration scroll compressor, it features advanced liquid injection technology to manage discharge temperatures effectively during low-evaporator-temp operation. This specific ZF18K4E-TF5-961 model serves as the official direct replacement for ZF18K4E-TF5-931. Note the critical mechanical upgrade: the -961 utilizes Rotolock connections (1-1/4" suction x 1" discharge), whereas the legacy -931 utilized sweat stub-outs. Designed with 70% fewer moving parts than reciprocating units, it ensures superior liquid handling and isentropic efficiency for 24/7 reliability in walk-in freezers and reach-in units. The BOM 961 configuration includes a sight glass and oil access fitting for streamlined maintenance.
Key Benefits for the Contractor- Direct Swap Compatibility: Engineered as the factory-authorized replacement for the ZF18K4E-TF5-931, simplifying field retrofits.
- Multi-Refrigerant Versatility: Approved for use with R-22, R-404A, R-507, and modern HFO blends like R-448A and R-449A.
- Enhanced Liquid Handling: Features Copeland’s axial and radial compliance for superior liquid handling and debris tolerance.
- Optimized Low-Temp Performance: Integrated liquid injection port protects against overheated discharge during deep refrigeration cycles.
- Durable Infrastructure: Heavy-duty 3-phase motor with internal inherent protection and POE oil charge.
Is the ZF18K4E-TF5-961 compatible with existing ZF18K4E-TF5-931 piping?
While the performance data is identical, the -961 uses Rotolock connections while the -931 uses sweat. You will need Rotolock-to-sweat adapters or new fittings if you are replacing a sweat-style unit.
What oil should be used in this compressor?
This unit comes pre-charged with Polyolester (POE) oil, making it compatible with HFCs and HFO blends. If using with R-22, ensure the system oil is compatible with your specific application requirements.
Does this unit include the liquid injection valve?
Yes, it is designed for liquid injection to maintain compression efficiency at low evaporator temperatures; always verify your specific capillary tube or DTC valve settings during installation.
