Trane COM6438 Compressor

Engineered for high-capacity commercial climate control, the Trane COM6438 is a durable 15-ton scroll compressor designed to maintain peak performance in demanding 460V 3-phase environments. Delivering a robust 180,000 BTU/H cooling capacity, this workhorse is the standard for large-scale rooftop units and industrial chillers. Utilizing a hermetically sealed scroll design, it provides superior efficiency and quieter operation compared to reciprocating models. The COM6438 compressor features sweat connection ports—specifically a 1-5/8" suction line and a 1-1/8" discharge line—ensuring a secure, leak-proof fit during field installation. Designed primarily for R-22 refrigerant systems using mineral oil, this unit is not A2L compatible and should be installed by a veteran technician to ensure proper phase alignment and oil return. Whether you are performing a full system overhaul or a critical component swap, this direct OEM replacement compressor offers the reliability required for 24/7 commercial operations.
