Trane YSJ120A4S0L12SA Rooftop Unit 10 Ton 460V 3 Phase

Product Description

The TRANE YSJ120A4S0L12SA is a 10-ton commercial packaged gas/electric rooftop unit built for light commercial and commercial HVAC rooftop applications. It delivers approximately 123,000 BTU/h of cooling capacity using R-410A refrigerant and operates on a 460-volt, 3-phase power supply. This is a self-contained gas-pack unit, meaning heating and cooling functions are housed in a single cabinet mounted at the rooftop curb. Licensed HVAC technicians with commercial equipment experience are the typical installing trade for this class of equipment.

This unit is suited for light commercial and commercial rooftop installations where a single packaged system handles both heating and cooling loads. Typical applications include retail spaces, small office buildings, and similar low-rise commercial structures where rooftop mounting is preferred and a combined gas-electric system eliminates the need for a separate air handler or furnace. The 10-ton capacity targets mid-size commercial zones requiring substantial cooling and heating output from a compact, curb-mounted footprint.
