Rheem 7.5 Ton R-454B Commercial Packaged Air Conditioner — RACDYB090ADG000AAAA0
The Rheem RACDYB090ADG000AAAA0 is the 460V three-phase build of Rheem's 7.5-ton Commercial Renaissance Classic Series rooftop unit, delivering 85,000 BTU/h AHRI net cooling at 11.2 EER and 14.8 IEER on R-454B. Because it runs on 460V, its compressor draws roughly 10.6 A versus 25.2 A on the 208/230V version, so larger facilities can feed several rooftops from one 460V service with lighter branch wiring. It keeps the two-stage scroll compressor, microchannel coils, and belt-drive VFD blower of the RACD platform in a convertible downflow or horizontal cabinet.
Is a 7.5-Ton Package Unit the Right Size?
This 7.5-ton unit opens Rheem's medium-commercial RACD range and is matched to cooling loads near 85,000 to 88,000 BTU/h, which for many commercial buildings works out to roughly 3,000 to 4,500 sq ft of conditioned space. Floor area is only a starting point, though — a full load calculation is what actually sizes a unit this large.
Occupant density, outside-air ventilation, roof and wall insulation, west-facing glazing, and process or kitchen heat all move the number well above or below what the square footage suggests. The two-stage compressor and VFD blower help this unit modulate to part loads, but that is not a substitute for a Manual N-style commercial load calculation, which is the right way to confirm this capacity fits the zone and keeps humidity in check.
Ideal for: Mid-size commercial zones inside schools, campuses, warehouses, and larger facilities that distribute power at 460V three-phase.

Recommended applications are general guidelines only. Actual capacity requirements depend on insulation, ventilation, occupancy, solar gain, ceiling height, and local design temperatures. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The RACDYB090ADG000AAAA0 ships as one factory-assembled, wired, and run-tested cabinet, so there is no field refrigerant line set to braze — it arrives charged with R-454B and ready to set, connect power and ducting, and commission. For curbed rooftop installs, pair it with the matching 7.5–12.5 Ton Rheem 14 in. roof curb (RXKG-DDD14).

Frequently Asked Questions
What size space will the RACDYB090ADG000AAAA0 cool?
It is matched to commercial cooling loads near 88,000 BTU/h (85,000 BTU/h AHRI net), which often lands around roughly 3,000 to 4,500 sq ft of commercial space. Because occupancy, ventilation, glazing, and internal heat gain move the real load, size it with a commercial load calculation rather than floor area alone.
Why choose the 460V RACDYB090ADG000AAAA0 over the 208/230V model?
On 460V, 3-Phase, 60 Hz this unit draws far less current — a 20 A minimum circuit ampacity and 30 A maximum overcurrent protection (compressor RLA 10.6 A) — versus the 208/230V build. That eases wiring and breaker sizing where a 460V service feeds several rooftops. If your panel is 208/230V, order the 208/230V three-phase 7.5-ton version instead.
Is this a two-stage unit, and does it have a VFD?
Yes. Every RACDYB unit provides two stages of cooling, and a variable frequency drive (VFD) on the belt-drive blower is standard. The two-stage scroll compressor and VFD blower modulate to hold comfort and improve humidity control at part load.
Can this package unit be installed downflow and horizontal?
Yes. Airflow is field-convertible between vertical downflow (for curbed rooftop openings) and horizontal side-flow. A matching 14 in. Rheem roof curb (RXKG-DDD14) is available for 7.5–12.5 ton RACD units.
Does this unit include heat?
This is a cooling-only (straight-air) packaged air conditioner. Electric resistance heater kits are available as accessories on the RACD platform; if built-in heating is required, a gas/electric or heat-pump package unit is the better starting point.
Does the RACD package unit include a warranty?
Yes. Rheem provides a limited warranty on the RACD series — typically a 5-year compressor and 1-year parts limited warranty for commercial applications. See the Rheem Limited Warranty document above for full terms and conditions.
