Trane DHC120H4RHA00E0 Dual-fuel Heat Pump 10 Ton 460V

Product Description

The TRANE DHC120H4RHA00E0 is a 10-ton commercial packaged dual-fuel heat pump built for rooftop installation in light commercial and commercial buildings. This self-contained unit delivers both heating and cooling from a single rooftop cabinet, combining electric heat pump operation with a gas heating stage for efficient year-round climate control. Rated at 10 tons of capacity and powered by a 460-volt, 3-phase electrical supply, it is sized for medium to large commercial zones. Installation and commissioning are typically handled by licensed commercial HVAC technicians.

The DHC120H4RHA00E0 is designed for rooftop packaged unit applications in commercial buildings where a single piece of equipment must handle both heating and cooling loads. The dual-fuel configuration allows the unit to operate the heat pump stage during moderate weather and switch to gas heating when outdoor temperatures drop, making it well suited for climates with cold winters. It is intended for new construction or direct replacement of existing commercial rooftop equipment requiring a 460-volt, 3-phase power source.

Key Features

• 10-ton cooling and heating capacity for medium to large commercial spaces
• Dual-fuel operation combining heat pump efficiency with gas backup heating
• 460-volt, 3-phase power supply for commercial electrical infrastructure
• Self-contained rooftop packaged design simplifies mechanical room requirements
• Single-unit installation covers both heating and cooling from one rooftop cabinet

Compatibility

Designed as an OEM-style rooftop packaged unit replacement or new installation for commercial buildings requiring a 10-ton dual-fuel heat pump on a 460-volt, 3-phase electrical system.

Installation Notes

Installation must be performed by a licensed commercial HVAC contractor familiar with rooftop packaged equipment, local mechanical codes, and NEC requirements for 460-volt, 3-phase electrical connections. Disconnect and lock out all electrical power and shut off gas supply before servicing or making any connections. Verify that the curb adapter and roof penetrations meet local building and energy codes before mounting. Do not operate the unit without confirming refrigerant circuit integrity and proper gas pressure at the unit inlet per the manufacturer service documentation.
