At 240,000 BTU on 460V 3-phase power with high heat gas output, this commercial rooftop packaged unit is built for major retail anchors in northern markets on 460V power, large institutional campuses in cold climate zones running high-voltage infrastructure, substantial office complexes in upper Midwest and New England markets on 460V electrical systems, large houses of worship in Mountain West and Great Plains cold climate geographies running high-voltage power, and major commercial facilities where the cooling load has pushed to the 20-ton tier, winter heating demands are severe enough that maximum gas heat output is non-negotiable, and the building's 460V electrical infrastructure makes standard voltage equipment the wrong specification regardless of tonnage or heat configuration. At 20-ton high heat on 460V power, this unit carries the heaviest combined heating and cooling load that a cold climate 460V commercial building can place on a single rooftop unit — and delivers the maximum electrical installation advantage the 460V configuration offers at the highest load level in the Foundation Series 460V high heat upper tier below the flagship.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe high heat configuration at 20-ton capacity on 460V power carries its greatest specification significance below the 25-ton flagship in the Foundation Series 460V cold climate lineup. At 240,000 BTU cooling output on high-voltage power in a cold climate building, the buildings that specify this unit are at the largest end of the cold climate 460V commercial building profile below maximum tonnage — major facilities with the highest thermal mass, the greatest exterior envelope exposure, the highest infiltration loads during severe cold events, and the most sustained winter heating demand of any 460V commercial building that falls short of the 25-ton ceiling. The consequence of a medium heat shortfall at 20-ton 460V capacity in a cold climate building is at its most severe below the flagship tier — the largest occupied areas without adequate heat during peak winter conditions, the longest recovery windows during cold snap events on high-voltage systems where service expertise requirements are highest, and the greatest operational and safety exposure of any Foundation Series 460V application below the 25-ton maximum. The 460V electrical configuration at 20-ton high heat capacity delivers the maximum amperage advantage in the Foundation Series 460V high heat upper tier below the flagship — at 240,000 BTU load with high heat gas output on 460V power, the amperage reduction versus a comparable 208\/230V unit is the most substantial below the 25-ton tier, translating into the greatest wire sizing reductions, the most significant conduit savings, and the highest switchgear cost reduction on large cold climate commercial electrical scopes where 20-ton rooftop equipment is specified alongside the most substantial high-voltage electrical infrastructure in the Foundation Series upper tier below maximum capacity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 13.0 IEER, this unit steps to the upper tier efficiency rating consistent with all 20-ton Foundation Series entries across every heat configuration and both voltage configurations — the step from 14.0 IEER at 17.5 tons to 13.0 IEER at 20 tons is addressed directly because buyers comparing 17.5 and 20-ton 460V high heat entries will scrutinize the efficiency difference, and the explanation that this step is consistent with commercial efficiency standards at this capacity level across the industry converts better than leaving it unaddressed at this price point and tonnage tier. For large cold climate building owners running 20-ton 460V equipment at maximum annual utilization through the longest heating and cooling seasons of any Foundation Series climate and voltage profile, 13.0 IEER at 240,000 BTU high heat output on 460V power still delivers meaningful operating cost efficiency at the scale and utilization profile where the absolute dollar value of efficiency performance is at its highest in the Foundation Series 460V high heat lineup below the flagship. R-454B refrigerant at 20-ton high heat 460V capacity eliminates the most disruptive mid-lifecycle service risk the building owner faces below the 25-ton tier — a forced refrigerant retrofit on a 20-ton high-voltage commercial unit in a large cold climate building running the highest combined annual heating and cooling operating hours of any Foundation Series 460V application below maximum tonnage, where both system failures and planned service events carry their highest cost and operational consequence below the flagship simultaneously.\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\"\u003e20 Ton \/ 240,000 BTU\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\"\u003eHeat Configuration\u003c\/td\u003e\n\u003ctd class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\"\u003eHigh Heat\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\"\u003e13.0\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\"\u003eGas\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\"\u003eFoundation Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003e\u003cbr\u003e\u003c\/h3\u003e","brand":"Trane","offers":[{"title":"Default Title","offer_id":55234327740707,"sku":"GDK240A4SHA1DQY","price":32190.0,"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-20-ton-commercial-gas-electric-packaged-unit-foundation-series-high-heat-r454b-460v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
