Copeland RST70C1E-PFV-959 Compressor

The Copeland RST70C1E-PFV-959 is a high-duty hermetic reciprocating compressor engineered for medium-temperature commercial refrigeration. Delivering a 7,150 BTU/hr cooling capacity at standard rating conditions, this model is a direct field replacement for the RST70C1-PFV-959. It operates on a 208-230V single-phase power supply and is optimized for use with R-404A and R-22 refrigerants. In technician terms, this unit is built for reliability in demanding environments, featuring a robust 3/8" OD suction connection and a 1/4" discharge for a clean sweat or braze installation. With an initial 22 oz. Polyolester (POE) oil charge, it is ready for integration into systems requiring stable mass flow and high volumetric efficiency. The 46 Locked Rotor Amps (LRA) and 7.7 Rated Load Amps (RLA) ensure consistent performance across its operational envelope, making it a standard choice for walk-in coolers and reach-in units.

Key Benefits for Contractors

• Direct Cross-Reference: Seamlessly replaces the previous RST70C1-PFV-959 model, minimizing downtime and pipework modifications.
• Dual Refrigerant Compatibility: Technicians can utilize this compressor in legacy R-22 systems or modern R-404A applications with appropriate oil management.
• Optimized Footprint: Standard mounting dimensions (8" x 4.8") allow for quick retrofitting in existing cabinet bases.
• High Torque Starting: Specifically designed to handle high pressures often encountered in commercial refrigeration start-up cycles.

Common Questions

What is the recommended refrigerant charge for this unit?
Charge levels should be determined by the specific OEM equipment specifications and the liquid line sight glass, though this unit is rated for R-404A and R-22.

Does this compressor come with an internal protector?
Yes, the RST70C1E-PFV-959 features internal line break protection to safeguard the motor from thermal overload and excessive current draw.

Can I use Mineral Oil with this model?
While the unit is charged with POE for R-404A compatibility, always verify the system's oil return requirements if retrofitting into an older R-22 system to ensure adequate lubrication.
