Trane YSJ120A4S0M099F Gas-pack 10 Ton 460V 3-phase

Product Description

The TRANE YSJ120A4S0M099F is a light commercial gas-pack packaged HVAC unit rated at 10 tons and designed for rooftop or ground-level installation. As a gas-pack configuration, the unit integrates gas heating and electric cooling into a single cabinet, eliminating the need for a separate indoor air handler or furnace. Operating on 460 volts, 3-phase power, this unit is suited for commercial buildings where three-phase electrical service is standard. Installation is typically performed by licensed commercial HVAC technicians with mechanical and electrical trade qualifications.

This packaged unit is intended for light commercial applications such as retail spaces, small office buildings, schools, and similar structures requiring a self-contained heating and cooling solution. The rooftop or ground-mount configuration allows for flexible siting depending on the building layout and mechanical infrastructure available at the jobsite. At 10 tons of cooling capacity, it is sized for medium commercial zones where single-zone or multi-zone ducted distribution is required.
