At 240,000 BTU on 460V 3-phase power with low heat gas configuration, this commercial rooftop packaged unit is built for major retail anchors, large distribution and fulfillment centers, substantial manufacturing facilities, large institutional buildings, and high-occupancy commercial complexes in warm to moderate climate zones where the cooling load has pushed beyond 17.5 tons, winter heating demands remain modest, and the building's 460V electrical infrastructure makes standard voltage equipment the wrong specification regardless of tonnage or heat configuration. At 20-ton capacity on 460V power, this unit delivers the highest cooling output in the Foundation Series 460V low heat lineup at the tonnage tier where the electrical and capacity advantages of the 460V configuration are at their most impactful on large commercial project economics.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe low heat configuration at 20-ton capacity on 460V power is the correct specification for large warm climate commercial buildings where 240,000 BTU of cooling output runs hard through extended warm climate seasons and the gas heating system exists primarily to handle brief cold snaps and limited shoulder-season conditions. At this tonnage, the fuel consumption overhead of an oversized heat configuration compounds significantly over extended service life — low heat keeps the gas system correctly matched to actual warm climate winter demand while the 460V electrical configuration delivers its largest amperage reduction in the Foundation Series low heat lineup. At 240,000 BTU load on 460V power, the difference in amperage draw versus a comparable 208\/230V unit is the most substantial in the Foundation Series low heat 460V series — translating into the greatest wire sizing reductions, the most significant conduit savings, and the highest switchgear cost reduction of any unit in the 460V low heat lineup, on large commercial electrical scopes where those savings are most financially meaningful.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt 13.0 IEER, this unit steps to the same efficiency tier as the 208\/230V 20-ton entry — consistent with commercial efficiency standards at this elevated capacity level and addressed directly here because buyers comparing across the 17.5 and 20-ton 460V entries will notice the step down from 14.0 IEER. The efficiency reduction reflects the engineering realities of delivering 240,000 BTU through a single-stage gas\/electric rooftop package at this capacity level, and 13.0 IEER still sits above minimum energy code thresholds in most U.S. jurisdictions at 20-ton capacity. R-454B refrigerant at 20-ton 460V capacity carries its highest importance in the Foundation Series 460V lineup — a mid-lifecycle refrigerant retrofit on a 20-ton high-voltage commercial unit in a large warm climate building running extended cooling seasons is the most disruptive and costly service event in the 460V Foundation Series, and R-454B specified at installation eliminates that scenario permanently across the full service life of the equipment.\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\"\u003eLow 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","brand":"Trane","offers":[{"title":"Default Title","offer_id":55231149113635,"sku":"GDK240A4SLA1DQY","price":29987.0,"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-low-heat-r454b-460v-3-phase","provider":"acunitsforless.com","version":"1.0","type":"link"}
