Rheem 6 Ton R-454B Commercial Packaged Air Conditioner — RACCYB072ACT000AAAA0
The Rheem RACCYB072ACT000AAAA0 is a 6-ton Commercial Classic Series packaged air conditioner rated at 68,500 BTU/h of AHRI net cooling with an 11.2 EER and 14.8 IEER, factory-charged with R-454B and configured for 208/230V three-phase power. Unlike the 3- through 5-ton models, this top-of-line RACCYB unit uses a two-stage scroll compressor, so it can run at part-load for quieter operation and tighter humidity control and step up to full capacity on design days. A 2,400 CFM blower and all-microchannel coils make it suited to large commercial zones on 208/230V service.
Is a 6-Ton Package Unit the Right Size?
As the top capacity in the RACCYB line, this 6-ton unit is matched to loads approaching 68,000 to 72,000 BTU/h, often roughly 2,400 to 3,600 sq ft of commercial space. Its two-stage compressor also helps in spaces where the load varies through the day, since it can hold a lower stage for much of the time rather than cycling a single fixed stage on and off.
Even at 6 tons, load drivers such as high occupancy, large glazing, make-up air, and cooking or process heat determine whether this is the right unit or whether the space needs more than one system. The two-stage compressor gives some tolerance for varying loads, but it is not a substitute for a real load calculation. Sizing from a commercial load analysis keeps staging effective and avoids the humidity problems that come with a grossly oversized single unit.
Ideal for: High-occupancy assembly spaces, big-box retail zones, large restaurants and banquet rooms, fitness centers, and sizable open offices where a single large unit with part-load staging is preferred, on 208/230V three-phase service.

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 RACCYB072ACT000AAAA0 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 3–6 Ton Rheem 14 in. roof curb (RXKG-DCC14).

Frequently Asked Questions
What size space will the RACCYB072ACT000AAAA0 cool?
It is matched to commercial cooling loads around 72,000 BTU/h (68,500 BTU/h AHRI net), which often lands near roughly 2,400 to 3,600 sq ft of light-commercial space. Because occupancy, ventilation, glazing, and internal heat gain move the real load, confirm the size with a commercial load calculation rather than floor area alone.
What power does the RACCYB072ACT000AAAA0 require?
This model is wired for 208/230V, 3-Phase, 60 Hz. It needs a minimum circuit ampacity of 38 A and a maximum overcurrent protection device of 50 A, with a compressor RLA of 19.2 A. If your building distributes power at 460V instead, order the 460V three-phase 6-ton RACCYB072ADT version of this unit.
Is this unit charged with R-454B, and does it have leak detection?
Yes. The RACCYB072ACT000AAAA0 is factory-charged with low-GWP R-454B (an A2L refrigerant) and includes a factory-installed refrigerant leak detection system that triggers a fault and mitigation sequence if a leak is sensed. Refrigerant charge is approximately 85 oz.
Can this package unit be installed downflow and horizontal?
Yes. Airflow is field-convertible between vertical downflow (for roof-curb installations) and horizontal side-flow, so the same unit works on a curbed rooftop opening or a slab with ducted side connections. A matching 14 in. Rheem roof curb (RXKG-DCC14) is available for 3–6 ton units.
Does this unit provide heat?
This is a cooling-only (straight-air) package air conditioner. Electric resistance heater kits are available as field- or factory-installed accessories on the RACC platform; if you need heating built in, a gas/electric or heat-pump package unit is the better starting point.
What makes the 6-ton RACCYB different from the 3–5 ton models?
Besides its higher 68,500 BTU/h AHRI net capacity and 2,400 CFM blower, the 6-ton RACCYB uses a two-stage scroll compressor, while the 3-, 4-, and 5-ton RACCYB units use a single-stage scroll. Two-stage operation lets it run at a lower stage for much of the season, improving part-load quietness and humidity control. Note that 6-ton commercial units are rated in EER/IEER (11.2 EER / 14.8 IEER) rather than SEER2.
