Trane COM11191 Compressor

The Trane COM11191 is a commercial-grade Alliance scroll compressor engineered specifically for technical replacement in residential and light commercial HVAC systems. This 2.7-ton compressor delivers a nominal 32,000 BTU/h and is the designated direct replacement for COM7040. Operating on a 208-230V single-phase 60Hz power supply, the unit utilizes R-22 refrigerant and comes pre-charged with POE (Polyolester Oil), making it suitable for both R-22 and certain retrofit applications where mineral oil is being phased out.

Built with durability in mind for high-demand cycles, the SXE032C1BPZ model features brazed stub-tube connections with a 3/4-inch suction line and a 1/2-inch discharge line. This OEM Trane scroll compressor provides quiet operation and high volumetric efficiency compared to reciprocating alternatives. Professional installation is required to ensure proper vacuum and moisture removal, maintaining system integrity in older R-22 infrastructure.

Key Benefits for Contractors

• Optimized Performance: Engineered by Alliance to provide high-efficiency cooling in 2.7-ton configurations.
• Versatile Lubrication: Standardized with POE oil to support modern service standards and component longevity.
• Rugged Build Quality: Features internal overloads and advanced scroll geometry to handle liquid slugging and debris more effectively than previous generations.

Common Questions

Is the COM11191 compatible with R-407C retrofits?
Yes, since this compressor uses POE oil, it is technically compatible with R-407C conversions, provided the system is thoroughly flushed and the expansion valve is adjusted for the different pressure-temperature relationship.

What are the electrical requirements for this 32,000 BTU compressor?
The unit runs on 208-230V, 1-phase power. Always verify the Locked Rotor Amps (LRA) and Rated Load Amps (RLA) on the existing contactor and breaker to ensure they meet the SXE032C1BPZ specifications.

Are any additional components required for installation?
When replacing a refrigerant-side component like this, it is standard trade practice to replace the liquid line filter drier and check the capacitor to ensure optimal startup torque.
