Trane YSJ300A3S0L0000 Rooftop Gas Electric Unit 25 Ton

Product Description

The TRANE YSJ300A3S0L0000 is a 25-ton commercial packaged rooftop gas/electric unit designed for large-scale simultaneous heating and cooling demands. It operates on 208/230 volts, 60 Hz, three-phase power and uses R-410A refrigerant. This self-contained rooftop unit integrates the gas heating section and electric cooling components into a single cabinet, reducing mechanical room requirements and simplifying service access. With a 300,000 BTU/h heating capacity and 25-ton cooling output, it is sized for mid- to large-scale commercial buildings. Installation and commissioning are typically handled by licensed commercial HVAC technicians.

The YSJ300A3S0L0000 is intended for commercial rooftop applications where a single packaged unit must handle both heating and cooling loads without separate indoor air handling equipment. Typical installations include retail centers, warehouses, schools, and office buildings requiring high-capacity climate control from a single rooftop-mounted cabinet. The gas/electric configuration means the unit draws natural gas for heating and uses the three-phase electrical supply for compressor and fan operation.

Key Features

Compatibility

Designed as a commercial packaged rooftop gas/electric unit for large commercial HVAC applications requiring 25-ton cooling and high-capacity gas heating in a single cabinet installation.

Installation Notes

Installation must be performed by a licensed commercial HVAC technician in accordance with local mechanical codes and the manufacturer's installation instructions. Disconnect and lock out all electrical power and shut off the gas supply before servicing or replacing any components. Roof curb alignment and structural load capacity should be verified prior to unit placement. Refrigerant handling requires EPA Section 608 certification.
