Trane GCC090A3ELB3YXA 7.5 Ton Gas Electric Packaged Rtu

Product Description

The TRANE GCC090A3ELB3YXA is a 7.5-ton combination gas-electric packaged rooftop unit (RTU) designed for commercial HVAC applications. The 090 designation in the model string indicates 90 MBh nominal gross cooling capacity. This unit integrates gas heating and electric cooling into a single cabinet, simplifying mechanical room requirements and reducing curb-side complexity. It operates on 208/230V three-phase power and uses R-410A refrigerant. Licensed commercial HVAC technicians and mechanical contractors handle installation and commissioning.

This packaged rooftop unit is intended for light commercial and commercial rooftop applications such as retail buildings, office spaces, and similar single-zone or multi-zone structures requiring a self-contained heating and cooling solution. The gas-electric configuration delivers both cooling and gas-fired heating from one rooftop-mounted cabinet, making it well suited for climates that demand significant heating and cooling loads. Installation follows a single-point electrical connection and a single gas supply connection at the unit.

Key Features

• 7.5-ton nominal cooling capacity for commercial-scale load requirements
• Gas-electric combination provides both heating and cooling from one cabinet
• 208/230V three-phase power input for commercial electrical service compatibility
• R-410A refrigerant circuit for current-generation refrigerant compliance
• Packaged rooftop configuration eliminates the need for a separate indoor air handler

Compatibility

Designed as an OEM packaged rooftop unit for commercial gas-electric HVAC applications. Consult the unit nameplate and Trane product documentation to confirm curb dimensions, duct connection sizing, and electrical supply requirements before installation.

Installation Notes

Installation of this rooftop unit must be performed by a licensed HVAC contractor in accordance with local mechanical codes, the National Electrical Code (NEC), and applicable gas codes such as the IFGC. Disconnect and lock out all electrical power and close the gas supply valve before performing any service work on the unit. The unit requires a properly sized roof curb matched to the unit footprint for weathertight installation. Do not operate the unit without verifying refrigerant charge, gas pressure, and airflow are within the ranges specified on the unit nameplate and in the Trane installation manual.
