Copeland RST45C1E-IAA-901 Compressor

The Copeland RST45C1E-IAA-901 is a high-performance hermetic reciprocating compressor engineered for extended medium-temperature commercial refrigeration applications. This 115V, single-phase motor delivers a cooling capacity of 6,720 BTU at high-temperature ratings, making it a reliable choice for reach-in coolers, ice machines, and display cases. Optimized for R407C refrigerant, this unit features a robust 1/2 HP motor and is also multi-refrigerant approved for compatible HFC and HFO blends including R-404A and R-507. With an EER of up to 6.9, it focuses on energy efficiency and thermal management through advanced suction gas management and high-flow valving. The unit includes a 15 oz initial charge of POE oil and features a standard 3/8" suction and 1/4" discharge stub connection. Built for durability in demanding industrial environments, this Copeland compressor 115V helps maintain precise temperature control while reducing operational sound levels via its integrated suction muffler and suspension design.

• Multi-Refrigerant Compatibility: Designed for R407C but versatile enough for R-404A, R-448A, and R-449A applications.
• High Durability Design: Features robust gaskets and a redesigned bearing surface to enhance oil flow and reduce mechanical wear.
• Optimized Starting: High-torque motor starts reliably under demanding load conditions common in commercial food service.
• Superior Liquid Handling: Patented Copeland technology improves the compressor's ability to manage liquid slugging.
• Quiet Operation: Internal suction muffler significantly reduces discharge pulse and vibration during high-load cycles.

Is this compressor compatible with Mineral Oil?
No, the RST45C1E-IAA-901 is factory-charged with Polyolester (POE) oil and must be used with POE to ensure proper lubrication and moisture management in HFC systems.

Can I use this for a walk-in freezer?
This model is rated for medium and high-temperature applications. For low-temperature or freezer applications, verify if the evaporating temperature range of your specific system falls within the -10°F to 45°F operating envelope of this series.

What are the mounting dimensions for a drop-in replacement?
This unit utilizes a standard quad-mounting pattern of 8.0" x 4.8", allowing for straightforward installation in most existing OEM chassis.
