Rheem 7.5 Ton R-454B Gas/Electric Package Unit, 150,000 BTU/h Heat — RGEDYB090ADG152AAAA0
The Rheem RGEDYB090ADG152AAAA0 is a 7.5-ton Commercial Renaissance Classic Series packaged gas/electric unit that combines R-454B air conditioning with two-stage natural gas heat in one medium-commercial rooftop cabinet. Wired for 460V 3-phase power, it delivers 85,000 BTU/h AHRI net cooling at 11.0 EER / 14.6 IEER and pairs it with a 150,000 BTU/h nominal, two-stage gas furnace (121,500 BTU/h output at 81% steady-state efficiency). Built around a two-stage scroll compressor, all-microchannel coils, factory refrigerant leak detection, and a belt-drive blower with a standard variable frequency drive (VFD), this convertible downflow/horizontal unit is a complete heating-and-cooling package for larger commercial buildings that want standard gas heat from a single 460V 3-phase rooftop.
Is a 7.5-Ton / 150,000 BTU Gas Package Unit the Right Size?
This unit matches 85,000 BTU/h of net cooling with a 150,000 BTU/h gas furnace, so it must be sized for two loads at once. On cooling, 7.5 tons typically suits roughly 3,000 to 4,500 sq ft of commercial space; on heating, the 121,500 BTU/h output (standard heat) should be matched to the building's design heating load and climate.
Cooling load depends on occupancy, ventilation, glazing, insulation, and local design temperatures, while heating load depends on climate, envelope, and ventilation air. The furnace is two-stage with 6 burners; first stage runs near 70% of full fire (about 85,050 BTU/h output) for quieter, more even heat, and the standard VFD supply fan improves part-load efficiency. Size both sides from an engineered commercial load calculation rather than floor area alone.
Ideal for: Larger retail floors, restaurants, worship and assembly spaces, and mid-size commercial buildings on 460V 3-phase power, needing dependable two-stage gas heat.
Cooling only? If you don't need gas heat, the 7.5-ton RACD 460V 3-phase straight-air package unit is the cooling-only equivalent. Compare 7.5-ton 150,000 BTU heat, 208/230V 3-phase.
Recommended applications are general guidelines only. Actual cooling and heating requirements depend on insulation, ventilation, occupancy, solar gain, climate, and design temperatures. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What cooling and heating capacity does the RGEDYB090ADG152AAAA0 provide?
It delivers 85,000 BTU/h AHRI net cooling (11.0 EER / 14.6 IEER) and 121,500 BTU/h of gas heating output from a 150,000 BTU/h nominal, two-stage furnace at 81% steady-state efficiency. Size both sides from an engineered commercial load calculation.
What power does the RGEDYB090ADG152AAAA0 require?
It is wired for 460V, 3-Phase, 60 Hz and, on the standard VFD-Medium drive, needs a 20 A minimum circuit ampacity with a 30 A maximum overcurrent protection device. If your panel is 208/230V, order the 208/230V version instead.
Is the furnace two-stage, and can it run on propane?
Yes. The gas furnace is two-stage with 6 burners and direct spark ignition; first stage runs near 70% of full fire. It ships for natural gas and can be field-converted to LP (propane) with the Rheem RXGJ-FP39 LP conversion kit for RGED gas packs.
Does the VFD supply fan come standard?
Yes. A variable frequency drive on the belt-drive supply fan is standard on every RGEDYB unit. It ramps the fan smoothly and runs at reduced speed at part load for lower energy use, quieter operation, and better dehumidification.
Can this unit be installed downflow and horizontal?
Yes. Airflow is field-convertible between vertical downflow (for curbed rooftop openings) and horizontal side-flow, so the same unit works on a curb or a slab with side duct connections.
Why choose the 150,000 BTU/h gas-heat option?
The 150,000 BTU/h furnace provides 121,500 BTU/h of standard heating output. Match the gas-heat size to your climate and design heating load.
