Trane YHC037E4RXA52WB Packaged Rooftop Gas Pack 3 Ton 460V

Product Description

The TRANE YHC037E4RXA52WB is a commercial packaged rooftop unit combining direct-expansion cooling with gas heat in a single self-contained cabinet. Rated at 3 tons of cooling capacity, it operates on 460 volts, 3-phase power, making it suited for light commercial applications where a single rooftop cabinet handles both heating and cooling loads. Licensed HVAC technicians install and service this type of equipment. The unit consolidates refrigerant circuit, heat exchanger, and controls into one weatherproof enclosure, reducing the number of penetrations through the roof deck.

This gas-pack rooftop unit is designed for light commercial buildings such as retail spaces, small offices, and similar structures requiring packaged HVAC solutions. The 3-ton cooling capacity fits typical zone loads in the 1,000 to 1,500 square foot range depending on climate and building envelope. The 460-volt, 3-phase electrical supply requirement is standard for commercial construction with a dedicated HVAC circuit. Installation is performed by licensed commercial HVAC contractors following local mechanical and electrical codes.
