At 15-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 running high-voltage electrical infrastructure where electrification mandates, gas infrastructure restrictions, new construction building codes, or owner-driven carbon reduction commitments require all-electric rooftop HVAC at step-up capacity on 460V power. At 15-ton capacity on 460V, the Precedent Series delivers the step-up all-electric tonnage the building needs, the high-voltage compatibility the electrical system requires, and the full amperage advantage of 460V operation at a load level where that advantage generates meaningful project savings on large all-electric commercial electrical scopes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003e460V Step-Up All-Electric — 15-Ton Heat Pump Performance on High-Voltage Power\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 15-ton capacity, the 460V Precedent Series heat pump addresses the step-up all-electric commercial building profile on high-voltage infrastructure — the building that has outgrown 12.5-ton capacity on the same 460V electrical system that made the 12.5-ton 460V Precedent Series unit the correct specification one tonnage tier lower. At 15-ton 460V heat pump load, the amperage reduction versus a comparable 208\/230V unit is more significant than at 12.5 tons — larger motor loads at step-up capacity mean a greater absolute amperage difference between voltage configurations, translating into more meaningful wire sizing reductions, larger conduit savings, and greater switchgear cost advantages on large all-electric commercial electrical scopes where 15-ton rooftop heat pump equipment is specified alongside substantial high-voltage electrical infrastructure. For developers and building owners in electrification-mandate markets running 460V infrastructure — new commercial construction in California, the Pacific Northwest, and Northeast markets under gas appliance restrictions — the 15-ton 460V Precedent Series unit delivers step-up all-electric tonnage, correct 460V voltage compatibility, and the most favorable all-electric electrical installation economics at this capacity tier in a single factory-assembled rooftop package that eliminates gas infrastructure entirely at the step-up capacity level.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 14.0 IEER and R-454B refrigerant, this unit maintains full commercial energy code compliance and complete refrigerant future-proofing at 15-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 step up in tonnage from 12.5 tons or the 460V electrical configuration. For large all-electric commercial buildings running 460V infrastructure through balanced annual heating and cooling cycles across 15 to 20-year equipment lifecycles, R-454B at installation eliminates the mid-lifecycle refrigerant retrofit risk across the full extended service life of a 15-ton high-voltage all-electric heat pump carrying the complete annual climate control burden without gas backup — the most disruptive and costly unplanned service event a large all-electric 460V commercial building faces when its sole rooftop HVAC source requires a refrigerant system intervention at step-up tonnage scale. Single-stage operation at 15-ton 460V heat pump capacity keeps commissioning straightforward and long-term service costs predictable across both heating and cooling seasons in large all-electric 460V commercial buildings where the heat pump is the sole source of year-round climate control on high-voltage power.\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\"\u003e15 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":55237901451555,"sku":"WSK180A4S","price":25595.0,"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-15-ton-commercial-packaged-heat-pump-precedent-series-r454b-460v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
