At 25-ton capacity with R-454B refrigerant on 460V 3-phase power, this commercial rooftop heat pump is the specification for major retail complexes, flagship distribution and fulfillment centers, large institutional campuses, substantial office developments, large manufacturing support facilities, and major multi-tenant commercial buildings in moderate climate zones running high-voltage electrical infrastructure where electrification mandates, gas appliance restrictions, new construction building codes, or owner-driven carbon reduction targets require all-electric rooftop HVAC at the absolute ceiling of what a single commercial heat pump can deliver on high-voltage power. Across the complete Precedent Series content set — 12.5-ton 208\/230V at one end, 25-ton 460V at the other — this is the unit that defines the top of the all-electric commercial rooftop heat pump range across every specification dimension simultaneously: maximum tonnage, maximum voltage, maximum BTU output, and maximum electrical installation efficiency in a single all-electric rooftop package with zero gas infrastructure at any point in the building's operational life.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e25-Ton 460V All-Electric Flagship — Maximum Capacity, Maximum Voltage, Zero Gas Infrastructure\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 25-ton capacity on 460V power, the Precedent Series heat pump reaches the absolute ceiling of the all-electric commercial rooftop lineup across both voltage configurations — the specification for the largest electrified commercial and light industrial buildings running high-voltage electrical infrastructure where both the all-electric commitment and the 460V voltage compatibility requirement are at their most consequential and most permanent simultaneously. For developers and building owners in electrification-mandate markets running 460V infrastructure at maximum commercial HVAC scale — major new commercial construction in California, the Pacific Northwest, Massachusetts, New York, and other Northeast markets leading the gas phase-out in commercial construction at the largest building scale — the 25-ton 460V Precedent Series unit is the rooftop heat pump specification that satisfies every electrification requirement at the absolute ceiling of standard commercial heat pump capacity on high-voltage power. The 460V electrical configuration at 25-ton all-electric heat pump capacity delivers the maximum amperage advantage across the entire Precedent Series lineup without exception — at maximum tonnage with all-electric heat pump operation on 460V power, the amperage reduction versus a comparable 208\/230V unit is the largest in the series, translating into the greatest wire sizing reductions, the most significant conduit savings, the highest switchgear cost reduction, and the largest overall electrical installation cost advantage of any unit in the complete Precedent Series lineup across both voltage configurations and all four tonnage tiers. One 25-ton 460V all-electric rooftop unit eliminates gas infrastructure entirely at the absolute ceiling of Precedent Series capacity on high-voltage power — no gas meter, no rooftop gas line, no combustion components, no dual-fuel commissioning on 460V systems, no gas appliance permits at maximum commercial scale, and no gas service relationship for the complete operational life of the building's primary high-voltage HVAC system at the highest all-electric capacity the Precedent Series delivers. At 25-ton 460V capacity, that gas infrastructure elimination carries its highest financial value in the Precedent Series — the avoided gas infrastructure investment at maximum tonnage on a large high-voltage commercial building is at its greatest, and the long-term operating cost advantage of all-electric heat pump operation on 460V power versus gas\/electric at this scale compounds most significantly across the full equipment lifecycle of the flagship unit.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 12.9 IEER, R-454B refrigerant, and single-stage operation, the Precedent Series 25-ton 460V unit closes the complete all-electric commercial heat pump content matrix with full commercial energy code compliance, permanent refrigerant future-proofing, and operational simplicity at the most demanding all-electric specification point the Precedent Series addresses across any combination of tonnage and voltage. The 12.9 IEER at 25-ton 460V capacity is consistent with the Precedent Series efficiency standard across both voltage configurations at this tonnage tier — the 460V configuration carries no additional efficiency penalty versus the 208\/230V variant at maximum tonnage, and the 12.9 IEER holds consistent from the 20-ton tier through the 25-ton flagship across both voltage configurations throughout the Precedent Series. For large all-electric building owners running 25-ton 460V heat pump equipment through balanced annual heating and cooling cycles in moderate climate zones at the highest all-electric commercial rooftop capacity available on high-voltage power, 12.9 IEER at maximum Precedent Series capacity represents the highest absolute dollar value of efficiency performance in the entire Precedent Series lineup — maximum tonnage, maximum annual runtime across both seasons, maximum single-unit all-electric utility spend, and the largest high-voltage installation in the lineup combine to make the efficiency rating at 25-ton 460V capacity more financially impactful per efficiency point than at any lower tonnage or voltage configuration in the Precedent Series. R-454B refrigerant at 25-ton all-electric 460V capacity is the most consequential refrigerant specification decision in the entire Precedent Series across both voltage configurations — at maximum tonnage on maximum voltage in a large all-electric building fully dependent on a single rooftop heat pump for both peak summer cooling and peak winter heating without gas backup, a mid-lifecycle refrigerant retrofit represents the most disruptive, most costly, and most operationally impactful service event the Precedent Series addresses across its complete lineup, taking the building's sole high-voltage climate control source offline at maximum scale during either the peak cooling or peak heating season in a large commercial facility with no backup heating or cooling source. R-454B specified at installation eliminates that scenario permanently across the complete service life of the unit that defines the absolute ceiling of Precedent Series all-electric commercial rooftop heat pump performance in every direction.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eSpecifications at a Glance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"overflow-x-auto w-full px-2 mb-6\"\u003e\n\u003ctable class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\"\u003e\n\u003cthead class=\"text-left\"\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\"\u003eSpec\u003c\/th\u003e\n\u003cth scope=\"col\" class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eCapacity\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e25 Ton\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eSystem Type\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003ePackaged Heat Pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eIEER\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e12.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eRefrigerant\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eR-454B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eVoltage\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e460V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003ePhase\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003e3-Phase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eHeating\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eHeat Pump (Electric)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eCooling\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eElectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eStages\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eSingle Stage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eSeries\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003ePrecedent Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Trane","offers":[{"title":"Default Title","offer_id":55237928616227,"sku":"WSK300A4S","price":45910.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/1171\/5363\/files\/TraneGDK_9e5fd715-ae92-4ad3-860d-1ac9ce180485.png?v=1781331538","url":"https:\/\/www.acunitsforless.com\/products\/trane-25-ton-commercial-packaged-heat-pump-precedent-series-r454b-460v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
