Trane COM6426 Compressor

The Trane COM6426 is a professional-grade 9-ton scroll compressor engineered specifically for high-demand commercial HVACR applications. Operating on 460V 3-phase power, this hermetic unit utilizes a positive displacement scroll design to deliver consistent performance and high volumetric efficiency in R-22 refrigerant systems. With a cooling capacity of approximately 108,900 BTU/H, the COM6426 serves as a direct OEM replacement compressor for a variety of Trane and American Standard rooftop units and chillers. The unit features robust brazed stub tube connections (1-3/8 inch suction and 7/8 inch discharge) to ensure leak-free joints under high-pressure conditions. Weighing 215 lbs and utilizing mineral oil, this 3450 RPM motor is built for durability, featuring an internal overload protector for motor safety. When performing a swap, contractors should verify phase rotation to ensure the scroll rotates clockwise, maintaining the integrity of the internal components and the refrigeration cycle.

• Optimized Performance: Specifically designed for 9-ton commercial systems, ensuring exact 460V electrical compatibility.
• Durable Construction: Heavy-duty cast iron housing and precision scroll geometry offer high COP values and reduced vibration.
• Ease of Integration: Standardized brazed sweat connections allow for traditional copper-to-copper joining in the field.
• Reliable Operation: Operates at a steady 3450 RPM with internal protection to handle demanding thermal loads.

Is the Trane COM6426 compatible with R-410A?
No, this specific model is designed for R-22 refrigerant and utilizes mineral oil. Using it with R-410A or POE oil without following proper conversion protocols is not recommended for system longevity.

What are the suction and discharge line sizes?
The Trane COM6426 features a 1-3/8 inch suction line and a 7/8 inch discharge line, both utilizing brazed stub tube connections.

Does this compressor include a crankcase heater?
