Copeland RST45C1E-CAA-901 Compressor

The Copeland RST45C1E-CAA-901 is a high-performance hermetic reciprocating compressor engineered for extended medium-temperature refrigeration. Running on a 115V single-phase power supply at 60Hz, this 1/2+ HP motor delivers a nominal capacity of 4,250 BTU/hr. It is a versatile choice for field service, compatible with R404A, R407C, R448A, R449A, and R22 refrigerants, provided the correct POE oil is utilized. Designed for durability in demanding commercial refrigeration environments, the unit features 3/8" suction and 1/4" discharge ODF connections for straightforward brazing. With a cooling efficiency (EER) of up to 11.9 depending on the refrigerant and application, it balances aggressive pull-down performance with operational economy. This model serves as a direct replacement for obsolete RS43C2E-CAA-908 and RS43C1E-CAA-213 units. Whether you are servicing reach-in coolers or specialized food processing equipment, this compressor provides the reliability expected from the Copeland RST series.

• High Efficiency: Features a 11.9 EER rating, reducing long-term operational costs for your customers.
• Compact Footprint: Standard quad mounting (8.0" x 4.8") ensures a seamless fit in tight condensing units.
• Rugged Build: Built to handle the high compression ratios typical of medium-temperature refrigeration.

Common Questions

Is this compressor pre-charged with oil?
Yes, the Copeland RST45C1E-CAA-901 comes pre-charged with Polyolester (POE) oil, making it compatible with modern HFC and HFO blend refrigerants.

Can I use this for a low-temperature application?
This model is specifically designed for extended medium-temperature ranges. Using it for low-temp applications may lead to overheating and reduced lubricant viscosity.

What are the electrical requirements for the start kit?
As a 115V compressor, it requires a high-torque start capacitor and potential relay (typically parts 914-0036-09 and 940-0001-62) to ensure reliable starting under load.
