Rheem 6 Ton R-454B Commercial Packaged Air Conditioner — RACCYB072ADT000AAAA0
The Rheem RACCYB072ADT000AAAA0 is the 460V three-phase build of Rheem's 6-ton Commercial Classic Series package unit, delivering 68,500 BTU/h of AHRI net cooling at 11.2 EER and 14.8 IEER on R-454B refrigerant. Like the 208/230V 6-ton, it carries a two-stage scroll compressor for part-load efficiency and improved dehumidification, but its 460V wiring cuts rated compressor amperage to about half, easing branch-circuit and feeder sizing when multiple large rooftop units share one 460V service. It keeps the 2,400 CFM blower, microchannel coils, and convertible downflow/horizontal design.
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: Large commercial and institutional zones in facilities with 460V three-phase power, where several big rooftop units share one service and lighter branch-circuit wiring 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.

Frequently Asked Questions
What size space will the RACCYB072ADT000AAAA0 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.
Why choose the 460V RACCYB072ADT000AAAA0 over the 208/230V model?
On 460V, 3-Phase, 60 Hz this unit draws about half the amperage of the 208/230V build — a 18 A minimum circuit ampacity and 25 A maximum overcurrent protection, with a compressor RLA of 9.1 A. That eases wiring and breaker sizing where a 460V service feeds several units. If your panel is 208/230V, order the 208/230V three-phase 6-ton version instead.
Is this unit charged with R-454B, and does it have leak detection?
Yes. The RACCYB072ADT000AAAA0 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.
