Copeland RST45C1E-IAA-959 Compressor

The Copeland RST45C1E-IAA-959 is a high-performance hermetic reciprocating compressor specifically engineered for extended medium and high-temperature refrigeration applications. Operating on 115V 1PH power, this unit delivers a nominal capacity of 6720 BTU when utilizing R407C refrigerant. As a direct replacement for RST45C1E-IAA-108, it provides a drop-in solution for contractors servicing reach-ins, ice machines, and beverage dispensers. The inclusion of RotoComp technology ensures optimized efficiency and reduced noise levels during startup and continuous operation.

Built for durability in demanding commercial environments, the RST45C1E-IAA-959 features a Rotolock suction connection and a sweat discharge, facilitating secure high-pressure seals. This 1/2 HP model is pre-charged with POE oil, making it compatible with modern HFC refrigerants including R404A, R448A, and R449A. Techs should note the 54.5 Locked Rotor Amps (LRA) and 10.5 Rated Load Amps (RLA) when verifying circuit breaker and contactor sizing. Its compact RS-body design allows for installation in tight mechanical compartments without sacrificing thermal displacement or lift capacity.

• Direct Drop-In Compatibility: Seamlessly replaces the legacy RST45C1E-IAA-108 and RS43C2E-IAA-959 models.
• Multi-Refrigerant Versatility: Optimized for R407C but maintains high mass flow efficiency with R404A and R448A/R449A blends.
• Reliable Starting Torque: CSIR (Capacitor Start - Induction Run) motor design handles high head pressures frequently encountered in commercial kitchen equipment.
• Advanced Fluid Handling: Features improved valve plates and gaskets designed to resist liquid slugging and extend the service life of the hermetic compressor.

What refrigerant does the RST45C1E-IAA-959 use?
This unit is designed for R407C at high-temperature ratings but is also widely used with R404A for medium-temperature applications. Always verify the expansion valve and oil compatibility when switching refrigerants.

Is the electrical start kit included?
The 959 bill of materials typically includes the remote electrical components (start capacitor and relay) in-box, specifically matched for the 115V single-phase motor requirements.

What are the mounting dimensions for this RS-series compressor?
The unit utilizes standard 8.0" x 4.8" quad mounting feet, consistent with most Copeland RST and RS series frames in this tonnage range.
