Rheem 10 Ton R-454B Commercial Packaged Air Conditioner — RACDYB120ACG000AAAA0
The Rheem RACDYB120ACG000AAAA0 is a 10-ton Commercial Renaissance Classic Series packaged air conditioner rated at 114,000 BTU/h AHRI net cooling with an 11.2 EER and 14.8 IEER, factory-charged with R-454B and wired for 208/230V three-phase power. A two-stage scroll compressor, deep microchannel coils, and a belt-drive blower with standard VFD push 4,000 nominal CFM, so this convertible downflow/horizontal rooftop unit suits large open commercial zones — big-box retail, worship halls, and high-occupancy assembly spaces — on 208/230V service.
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-box retail zones, large worship and assembly halls, gymnasiums, banquet and event spaces, and sizable open-plan offices on 208/230V three-phase power.
Need more capacity? Step up to the 12.5-Ton Rheem R-454B 208/230V 3-Phase Package Unit (RACDYB150ACG000AAAA0) for larger zones that need more cooling capacity.
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 RACDYB120ACG000AAAA0 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 RACDYB120ACG000AAAA0 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.
What power does the RACDYB120ACG000AAAA0 require?
This unit is wired for 208/230V, 3-Phase, 60 Hz. On the standard VFD-Medium drive it needs a minimum circuit ampacity of 48 A and a maximum overcurrent protection device of 70 A (compressor RLA 26.5 A). If your building distributes power at 460V, order the 460V three-phase 10-ton version (RACDYB120ADG) 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.
