Copeland RST55C1E-CAA-901 Compressor

The Copeland RST55C1E-CAA-901 is a high-performance reciprocating compressor engineered for commercial refrigeration applications. Operable at 115V 1-Phase, this unit delivers a nominal 5,200 BTU/hr capacity optimized for R-404A refrigerant systems. Designed for high evaporation temperature (HET) and medium-pressure environments, it features a hermetic design that ensures long-term reliability in demanding walk-in coolers or reach-in units. The POZ oil lubrication system is factory-charged to handle HFC refrigerants, maintaining critical compressor efficiency and preventing oil logging in the evaporator. For contractors performing a replacement, ensure the start capacitor and relay are matched to the Locked Rotor Amps (LRA) rating to prevent premature motor failure. This replacement compressor provides the high starting torque necessary for systems using thermostatic expansion valves (TXV), ensuring stable head pressure and consistent thermal regulation during cycling.

Key Benefits

• High Starting Torque: Engineered for systems utilizing TXVs, ensuring reliable startups under high pressure.
• R-404A Optimized: Specifically designed to handle the mass flow and thermal properties of R-404A in commercial cooling.
• Compact Footprint: Standard mounting configuration allows for direct drop-in replacement in legacy refrigeration frameworks.
• Internal Protectors: Equipped with line-break internal motor protection to guard against thermal overloads and phase loss.

Common Questions

What is the primary application for the RST55C1E-CAA-901?
This model is primarily used in commercial high/medium-temperature refrigeration applications, such as food service equipment and reach-in coolers.

Does this compressor come with a charging port or internal oil?
It is shipped with a factory charge of POE oil. Always verify oil levels after installing a new liquid line filter drier to ensure proper system volume.

Can I use R-22 with this compressor?
No, this unit is specifically engineered for R-404A and R-507. Using incompatible refrigerants will lead to oil breakdown and mechanical failure.
