At 12.5-ton capacity with R-454B refrigerant on 460V 3-phase power, this commercial rooftop heat pump delivers both heating and cooling through a single all-electric refrigerant circuit for large retail centers, major office buildings, substantial institutional facilities, large houses of worship, schools, and high-occupancy commercial buildings in moderate climate zones that run 460V electrical infrastructure and require all-electric rooftop HVAC — whether driven by electrification mandates, gas infrastructure restrictions, new construction building codes, or owner-driven ESG and carbon reduction commitments. The 460V configuration at 12.5-ton heat pump capacity adds a meaningful practical dimension to the all-electric specification — buildings running 460V infrastructure that have already committed to all-electric HVAC get the full amperage advantage of high-voltage power at heat pump entry capacity, combining the gas elimination benefit of the Precedent Series with the electrical installation efficiency of 460V operation in a single factory-assembled rooftop package.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e460V All-Electric Heat Pump — Combining Electrification and High-Voltage Efficiency\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe 460V configuration of the Precedent Series 12.5-ton heat pump addresses a specific and growing commercial building profile — all-electric commercial facilities running high-voltage electrical infrastructure where both the gas elimination requirement and the 460V voltage compatibility requirement are non-negotiable simultaneously. Manufacturing support offices in 460V industrial facilities pursuing electrification commitments, new institutional construction in 460V buildings in electrification-mandate jurisdictions, and large commercial facilities in California, the Pacific Northwest, and the Northeast running 460V power under gas appliance restrictions — these are the buildings where the 12.5-ton 460V Precedent Series heat pump is the only specification that addresses both requirements at once. The amperage reduction at 12.5-ton 460V heat pump capacity versus a comparable 208\/230V unit translates into smaller wire gauges, reduced conduit sizing, lower switchgear requirements, and real electrical installation cost savings — on all-electric commercial buildings where the electrical scope is already substantial from the elimination of gas infrastructure, that amperage advantage compounds the installation cost efficiency of the all-electric specification at entry heat pump tonnage.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 14.0 IEER and R-454B refrigerant, this unit delivers full commercial energy code compliance and complete refrigerant future-proofing at 12.5-ton all-electric 460V capacity — consistent with the Precedent Series efficiency standard at this tonnage across both voltage configurations, with no efficiency penalty for the 460V electrical specification. For large all-electric commercial buildings running 460V infrastructure through balanced annual heating and cooling cycles, R-454B at installation eliminates the mid-lifecycle refrigerant retrofit risk across the full service life of a 12.5-ton high-voltage all-electric heat pump carrying the complete annual climate control burden without gas backup — the most disruptive mid-lifecycle service event a large all-electric 460V commercial building faces when its sole rooftop HVAC source goes offline for refrigerant retrofit at any point in a 15 to 20-year service life. Single-stage operation at 12.5-ton 460V heat pump capacity keeps commissioning clean, diagnostics fast, and long-term service costs predictable across both heating and cooling seasons in large all-electric 460V commercial buildings where system availability is at its most critical without a gas backup heating source.\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\"\u003e12.5 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\"\u003e14.0\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":55237888770339,"sku":"WSK150A4S","price":22578.0,"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-12-5-ton-commercial-packaged-heat-pump-precedent-series-r454b-460v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
