Trane YSC036G3RMB20CP Rooftop Gas-pack 3 Ton 208/230V

Product Description

The TRANE YSC036G3RMB20CP is a packaged rooftop unit (RTU) configured as a gas-pack, meaning it integrates both a gas heating section and a direct-expansion cooling system in a single cabinet. Rated at 3 tons (36,000 BTU/h) of cooling capacity, the unit operates on 208/230V, 3-phase power and uses R-410A refrigerant. It is designed for commercial rooftop installations and is intended for service by licensed HVAC technicians familiar with commercial packaged equipment. The gas-pack configuration eliminates the need for a separate indoor furnace or air handler, consolidating the heating and cooling system into one rooftop-mounted assembly.

The YSC036G3RMB20CP is suited for light commercial applications such as small office buildings, retail spaces, and similar single-zone or multi-zone commercial structures requiring both heating and cooling from a single rooftop platform. The 3-ton capacity targets spaces in the range typical of small commercial occupancies. The 3-phase electrical configuration is standard for commercial construction where three-phase service is available at the rooftop disconnect. This unit is part of the Trane Precedent product line, which is positioned for commercial replacement and new-construction rooftop applications.
