Trane COM11213 Compressor

The Trane COM11213 is a high-performance 3.9 ton compressor engineered for commercial and residential split systems operating on R22 refrigerant. Delivering 48,000 BTU, this 230V 3-phase compressor serves as the direct OEM replacement for COM3745. As a veteran technician knows, drop-in compatibility is critical for labor efficiency; for split system applications, ensure the installation includes KIT18829 if transitioning from a package unit configuration. Note that this model is not a suitable substitute for heat pump applications. To ensure optimal lubrication and prevent liquid slugging during off-cycles, it is highly recommended to order sump heater HTR12893. This scroll compressor is designed for high-static pressure environments, maintaining consistent volumetric efficiency and thermal stability in demanding HVACR cycles. By utilizing genuine Trane OEM parts, contractors ensure the system meets original factory sub-cooling and superheat specifications.

Key Benefits for Field Technicians:

• Direct OEM Match: Exact COM3745 replacement ensures suction and discharge line alignment.
• Industrial Grade Power: 230V 3-phase motor provides high starting torque for rapid cooling.
• Precision Cooling: 48,000 BTU capacity optimized for 3.9 ton HVAC systems.
• System Reliability: Engineered for legacy R22 refrigerant system maintenance and rehabilitation.

Common Questions:

Is the COM11213 compatible with R410A systems?
No, this compressor is specifically designed for R22 refrigerant and mineral oil environments. Using it with R410A will lead to immediate mechanical failure.

What is required for a package system installation?
If you are installing this in a package system rather than a split system, you must use KIT18829 to ensure proper fitment and operation.

Does this unit work for heat pumps?
There is no direct replacement for heat pump versions of this model; this compressor is strictly for cooling-only units.
