Trane 12.5 Ton 140,000 BTU Commercial Gas/Electric Packaged Unit | 14.0 IEER | R-454B | 460V 3-Phase | Foundation Series | Single Stage

Here's the full content package for the 12.5-ton 460V variant: Optimized Title Trane 12.5 Ton 140,000 BTU Commercial Gas/Electric Packaged Unit | 14.0 IEER | R-454B | 460V 3-Phase | Foundation Series | Single Stage Product Description Trane Foundation Series 12.5 Ton Commercial Gas/Electric Packaged Unit — 460V 3-Phase Maximum Capacity for Heavy Commercial and Industrial Buildings The Trane Foundation Series 12.5-ton 460V unit is the flagship of the lineup. At 140,000 BTU with 460V 3-phase power compatibility, this gas/electric rooftop packaged unit is engineered for the most demanding commercial and light industrial applications: large-format retail, big-box distribution centers, manufacturing facilities, large institutional buildings, multi-tenant commercial complexes, and any high-load application where a single rooftop unit needs to carry maximum tonnage through a high-voltage electrical system. When the building is large, the load is heavy, the electrical system runs 460V, and the margin for error is zero — this is the unit that gets specified. 14.0 IEER — Sustained Efficiency at Maximum Commercial Load At 12.5-ton capacity, the Foundation Series delivers a 14.0 IEER — meeting commercial energy code requirements at the highest tonnage tier in the lineup. For large facilities running equipment at peak utilization for extended hours, that efficiency rating at full load is where annual operating cost savings are most impactful. Note that the IEER steps to 14.0 at this capacity tier versus the 14.6 rating of smaller Foundation Series units — consistent with commercial efficiency standards at this tonnage level and still comfortably above minimum code thresholds in most U.S. jurisdictions. 460V 3-Phase — Factory-Rated for High-Voltage Infrastructure At 12.5-ton capacity, the case for 460V power is strongest. The amperage reduction versus a comparable 208/230V unit at this load level is substantial — translating directly into smaller wire gauges, reduced conduit sizing, lower switchgear requirements, and meaningful electrical installation cost savings on large commercial projects. This unit is factory-built and rated for 460V, not field-modified — ensuring proper motor sizing, correct protection components, and full warranty validity from day one. R-454B Refrigerant — Essential at the Highest Capacity Tier The buildings that specify 12.5-ton 460V rooftop equipment are built for long service lives. A refrigerant retrofit on a 12.5-ton commercial unit mid-lifecycle — equipment removal, refrigerant recovery, component replacement, recommissioning — is a major operational and financial disruption. R-454B eliminates that risk entirely. Specified from the factory on this unit, R-454B keeps the building owner fully compliant with current and upcoming refrigerant regulations across the full service life of the equipment, with no retrofit exposure. All-In-One Gas/Electric at 12.5-Ton Scale — Maximum Consolidation At 12.5 tons, the value of consolidating gas heating and electric cooling into a single factory-assembled rooftop package is at its highest. One unit, one roof curb, one set of roof penetrations, one electrical connection point, one refrigerant circuit, one service contractor. No separate heating plant to engineer and install. No dual-system controls to commission and maintain. For contractors managing complex large commercial mechanical scopes, that consolidation reduces project risk, installation time, and coordination overhead at every phase. Single-Stage Operation — Controlled Simplicity at Maximum Tonnage Single-stage control at 12.5-ton capacity keeps the system architecture clean and the long-term service profile predictable. At this tonnage, diagnostic complexity is expensive — longer service windows, more specialized technicians, higher parts exposure per call. Single-stage design eliminates unnecessary control complexity without compromising any of the high-output performance the building demands.
