Rheem 10 Ton R-454B Commercial Packaged Air Conditioner — RACDYB120ADG000AAAA0
The Rheem RACDYB120ADG000AAAA0 is the 460V three-phase build of Rheem's 10-ton Commercial Renaissance Classic Series rooftop unit, delivering 114,000 BTU/h AHRI net cooling at 11.2 EER and 14.8 IEER on R-454B. Its 460V wiring drops compressor draw to about 14.0 A from 26.5 A on the 208/230V model, easing feeder and breaker sizing when several 10-ton units share one 460V service. It keeps the two-stage scroll compressor, microchannel coils, and 4,000 CFM belt-drive VFD blower in a convertible downflow or horizontal cabinet.
Is a 10-Ton Package Unit the Right Size?
This 10-ton unit is a workhorse capacity for large commercial zones, matched to loads near 114,000 to 118,000 BTU/h — frequently roughly 4,000 to 6,000 sq ft. Because it serves big open areas with high internal gains, sizing from an actual load analysis rather than square footage is essential.
High occupancy, large make-up air requirements, extensive glazing, and cooking or equipment loads can each swing a 10-ton requirement by a ton or more. An assembly space packed with people behaves very differently from a sparsely occupied showroom of equal footprint. Sizing from a commercial load calculation keeps the two-stage compressor staging effective and protects latent (humidity) performance.
Ideal for: Big open commercial and institutional zones in facilities with 460V three-phase distribution, where lighter branch wiring on large units is an advantage.

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 RACDYB120ADG000AAAA0 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 RACDYB120ADG000AAAA0 cool?
It is matched to commercial cooling loads near 118,000 BTU/h (114,000 BTU/h AHRI net), which often lands around roughly 4,000 to 6,000 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 RACDYB120ADG000AAAA0 over the 208/230V model?
On 460V, 3-Phase, 60 Hz this unit draws far less current — a 25 A minimum circuit ampacity and 35 A maximum overcurrent protection (compressor RLA 14.0 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 10-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.
