Trane 7.5 Ton 86,000 BTU Commercial Gas/Electric Packaged Unit | 14.6 IEER | R-454B | 460V 3-Phase | Foundation Series | Single Stage

Trane Foundation Series 7.5 Ton Commercial Gas/Electric Packaged Unit — 460V 3-Phase for High-Voltage Commercial Applications The Trane Foundation Series 7.5-ton unit in 460V 3-phase configuration is built for commercial buildings where high-voltage electrical infrastructure is already in place. At 86,000 BTU, this gas/electric rooftop packaged unit delivers the same proven Foundation Series performance and efficiency — now matched to the 460V 3-phase power systems common in manufacturing facilities, industrial buildings, larger office complexes, and institutional construction. 14.6 IEER Efficiency — Code-Compliant at 460V With a 14.6 IEER and 11.6 EER rating, this 460V unit meets current commercial energy efficiency standards without compromise. The same efficiency numbers as the 208/230V variant, delivered through a 460V-rated electrical design optimized for high-voltage commercial power systems. Lower amperage draw at 460V also means reduced wire sizing requirements and potential savings on electrical installation costs. R-454B Refrigerant — Future-Proofed Across Both Voltage Configurations Operating on R-454B, this unit is fully aligned with the ongoing refrigerant transition away from R-410A. For buildings already investing in 460V infrastructure — typically longer-lifecycle commercial and industrial facilities — specifying R-454B refrigerant at installation is especially important. These buildings hold equipment longer, making mid-lifecycle refrigerant retrofits more disruptive and costly to avoid. 460V 3-Phase — The Right Unit for High-Voltage Buildings The 460V configuration is the critical differentiator here. Buildings with 460V 3-phase service should never be fitted with 208/230V equipment — mismatched voltage causes premature component failure, voided warranties, and serious safety risks. This unit is factory-built and rated for 460V, ensuring full compatibility, correct motor sizing, and proper protection components for high-voltage commercial power. Integrated Gas/Electric Design — Single Rooftop Package Gas heating and electric cooling combined in one rooftop unit means no separate heating plant, no additional mechanical space, and no dual-system controls to manage. Single-stage operation keeps commissioning straightforward and long-term service simple — whether the building runs 208V or 460V power. Why the 460V Configuration Gets Specified Factory-rated 460V design — not an aftermarket modification Lower amperage draw reduces wire sizing and conduit costs versus 208/230V Same 14.6 IEER efficiency as the standard voltage variant R-454B refrigerant protects long-lifecycle industrial and institutional buildings from retrofit costs All-in-one gas/electric rooftop package eliminates separate heating equipment Single-stage simplicity reduces commissioning time and service complexity Trane Foundation Series reliability with full factory warranty Specifications at a Glance Spec Detail Capacity 7.5 Ton / 86,000 BTU IEER 14.6 EER 11.6 Refrigerant R-454B Voltage 460V Phase 3-Phase Heating Gas Cooling Electric Stages Single Stage Series Foundation Series
