Trane COM11140 Compressor

The Trane COM11140 is a high-efficiency 7.5-ton scroll compressor designed for commercial HVAC applications requiring 230V 3-phase power. Engineered as the direct functional replacement for the Trane COM7477, this unit maintains the same footprint and suction/discharge port configurations to ensure seamless field integration. Operating with R410A refrigerant, it features a robust internal motor protection system and optimized scroll plates for superior compression efficiency and lower acoustic profiles. When performing a compressor changeout, technicians should verify oil compatibility and ensure the thermal expansion valve is matched for 7.5-ton capacity. This hermetic compressor is built to withstand high condensing temperatures, making it a reliable choice for Trane rooftop units and split systems. Its durable construction handles high-demand cycling while maintaining tight volumetric efficiency across varying load conditions.
