Copeland RST45C1E-CAV-901 Compressor

The Copeland RST45C1E-CAV-901 is a high-performance hermetic reciprocating compressor specifically engineered for extended medium temperature refrigeration applications. As the direct replacement for RST45C1-CAV-901, this unit is built on the R*T platform, providing 4,240 BTU/hr of cooling capacity at a 20°F evaporator temperature. Operating on a 208/230V single-phase power supply, it features a Capacitor Start/Capacitor Run (CSCR) motor designed for reliable starts in high-demand environments. This 1/2 HP model is optimized for R404A refrigerant but also maintains compatibility with multi-refrigerant systems including R-448A and R-449A. Technicians can rely on the 3/8-inch sweat suction and 1/4-inch discharge connections for secure braze-on installation. Advanced fluid management, including high-flow valving and patented suction mufflers, ensures superior liquid handling and reduced sound levels in commercial reach-ins, ice machines, and walk-in coolers.

• Universal Compatibility: Serves as a versatile solution for food service, medical, and industrial refrigeration systems requiring R404A compressors.
• Enhanced Durability: Equipped with external inherent protection and robust adhesive-coated gaskets to prevent leaks and motor burnout under stress.
• High Efficiency: Features a redesigned valve plate and bearing surfaces that improve oil flow and reduce mechanical wear for a lower total cost of ownership.
• Quiet Operation: Integrated discharge system and suspension design minimize vibration, essential for front-of-house equipment.

Is the RST45C1E-CAV-901 compatible with R-22 systems?
While originally part of the R*T line that supported R-22, this "E" series model is specifically optimized for HFC and HFO blends like R-404A, R-448A, and R-449A using POE oil. Always verify oil compatibility if retrofitting older systems.

What are the mounting dimensions for this unit?
The industry-standard mounting pattern for this frame is 8 inches by 4.8 inches, with a total height of 9.3 inches to the mounting holes, ensuring a drop-in fit for standard commercial footprints.

Does this compressor include start components?
Yes, this model typically ships as a bill-of-materials that includes the necessary single-phase start components and mounting hardware required for a full field replacement.
