Trane COM8289 Compressor

For large-scale commercial air conditioning applications, the Trane COM8289 serves as a direct OEM replacement scroll compressor engineered for high-demand reliability. This 7.5-ton compressor operates on a 460V 3-phase electrical configuration, making it a staple for industrial cooling and retail HVAC systems. Using R-22 refrigerant and mineral oil, it features a hermetic scroll design that ensures quieter operation and higher efficiency compared to older reciprocating units. The sweat connection (brazed stub tubes) with a 1-1/8 inch suction and 1/2 inch discharge allows for secure, leak-resistant installation. Built by Trane, the COM8289 compressor is designed for rigorous 60 Hz cycles. Experienced contractors consistently specify this 460v 3ph HVAC compressor to restore system performance in commercial rooftop units where drop-in compatibility and 90,000 BTU cooling capacity are required. This 147-lb steel shell unit is built for sustained high-temperature air conditioning service without the maintenance overhead of semi-hermetic alternatives.
