Trane 8.5 Ton 104,000 BTU Commercial Gas/Electric Packaged Unit | 14.6 IEER | R-454B | 460V 3-Phase | Foundation Series | Single Stage

Trane Foundation Series 8.5 Ton Commercial Gas/Electric Packaged Unit — 460V 3-Phase High-Capacity Performance for Demanding Commercial Buildings When your building runs 460V 3-phase power and needs more than 7.5 tons to cover the load, the Trane Foundation Series 8.5-ton unit in 460V configuration is the natural next step. At 104,000 BTU, this gas/electric rooftop packaged unit delivers high-output heating and cooling across larger commercial spaces — retail stores, mid-size office buildings, restaurants, schools, and light industrial facilities — all matched to the high-voltage electrical infrastructure these buildings commonly run. 14.6 IEER — Full Efficiency at Elevated Capacity and Voltage Hitting 14.6 IEER and 11.6 EER at 8.5-ton capacity in a 460V configuration is where Trane's engineering earns its reputation. Energy code compliance doesn't take a back seat just because the load is heavier or the voltage is higher. For facility managers and building owners, that means the step up in tonnage doesn't have to mean a step up in operating costs. Lower Amperage Draw — A Practical 460V Advantage At 460V, this unit draws significantly lower amperage than its 208/230V counterpart delivering the same 104,000 BTU output. That difference matters at installation — smaller wire gauges, reduced conduit sizing, and lower electrical infrastructure costs. For contractors, it simplifies the electrical rough-in. For building owners, it reduces upfront installation expense without sacrificing any performance. R-454B Refrigerant — Specified Right for Long-Lifecycle Buildings Buildings running 460V 3-phase infrastructure tend to be built for the long term — industrial facilities, institutional buildings, larger commercial complexes. Those are exactly the buildings where specifying R-454B refrigerant at installation matters most. With R-410A facing ongoing regulatory phase-down, locking in R-454B now means no mid-lifecycle retrofit costs, no refrigerant supply concerns, and no compliance exposure over the equipment's full service life. Integrated Gas/Electric — One Unit, Complete Climate Control Gas heating and electric cooling in a single factory-assembled rooftop package eliminates the need for a separate heating plant, additional mechanical room space, or complex dual-system controls. At 8.5-ton capacity in a 460V building, the all-in-one design is a significant practical and cost advantage — fewer penetrations, one electrical connection point, and one service relationship for the entire HVAC system. Single-Stage Operation — Straightforward at Scale Single-stage control keeps commissioning fast, diagnostics simple, and service calls shorter. At 8.5 tons in a high-voltage commercial installation, that simplicity has real value — especially for facilities teams managing multiple rooftop units or contractors working on tight project timelines.
