This unmixed, uninhibited thermal fluid is engineered for industrial and commercial systems that do not require active chemical corrosion inhibitors, or for facilities where technicians will inject specialized, site-specific inhibitor packages. By arriving already diluted with purified water, it entirely eliminates the risk of scaling and mineral buildup associated with hard tap water during on-site mixing. Purchasing a factory-blended 30% concentration ensures exact fluid density and consistent thermal conductivity across your entire network, maximizing heat transfer efficiency while minimizing the cold-weather viscosity load on mechanical pumps.\u003c\/p\u003e\n\n\u003ch3\u003eBest Applications for This Grade\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCommercial HVAC and closed-loop hydronic heating networks, commonly applied in facility climate control, where a precise 30% uninhibited ratio maintains steady flow rates and prevents cold-weather line freezing.\u003c\/li\u003e\n\u003cli\u003eGeothermal heat pump circuits, commonly applied in industrial temperature management, as this specific concentration provides an exact balance between necessary freeze protection and optimal thermal conductivity without overburdening system circulators.\u003c\/li\u003e\n\u003cli\u003eSeasonal winterization of marine engines, industrial cooling towers, and facility plumbing lines, where flushing equipment with a factory-mixed 30% solution effectively displaces water to prevent catastrophic pipe bursts during off-season storage.\u003c\/li\u003e\n\u003cli\u003eCustom heat transfer operations, commonly applied in large-scale manufacturing, serving as a pure base fluid for engineers who require strict control over their own proprietary chemical additives and corrosion prevention regimens.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen to Choose a Different Grade\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIf your mechanical system operates with mixed metal components—such as copper, brass, steel, or cast iron—and requires robust, built-in chemical protection against oxidation and galvanic corrosion, choose 30% Propylene Glycol Inhibited.\u003c\/li\u003e\n\u003cli\u003eIf your facility is located in a severe winter climate or operates specialized chilling equipment requiring operational freeze protection well below 9°F (-13°C), move up the concentration ladder and choose 40% Propylene Glycol Technical Grade or 50% Propylene Glycol Technical Grade.\u003c\/li\u003e\n\u003cli\u003eIf your maintenance protocol requires blending custom fluid ratios on-site to address varying seasonal temperature fluctuations across multiple independent cooling loops, choose 100% Propylene Glycol Technical Grade to serve as your raw base material.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Alliance Chemical","offers":[{"title":"1 Quart \/ 1 Quart","offer_id":42585596166186,"sku":"DTQ-5G1-820","price":20.94,"currency_code":"USD","in_stock":true},{"title":"1 Quart \/ 2 Quarts","offer_id":42585596198954,"sku":"NFX-7J8-134","price":30.02,"currency_code":"USD","in_stock":true},{"title":"1 Quart \/ 4 Quarts","offer_id":42585596231722,"sku":"CQM-3S7-658","price":50.0,"currency_code":"USD","in_stock":true},{"title":"1 Quart \/ 8 Quarts","offer_id":42585596264490,"sku":"HWT-9N5-742","price":75.0,"currency_code":"USD","in_stock":true},{"title":"1 Gallon \/ 1 Gallon","offer_id":42585596297258,"sku":"JLK-1C8-507","price":40.0,"currency_code":"USD","in_stock":true},{"title":"1 Gallon \/ 2 Gallons","offer_id":42585596330026,"sku":"MQR-8W6-921","price":70.0,"currency_code":"USD","in_stock":true},{"title":"1 Gallon \/ 4 Gallon Case","offer_id":42585596362794,"sku":"VBS-4Y2-310","price":125.0,"currency_code":"USD","in_stock":true},{"title":"1 Gallon \/ 4 Gallons x 36 Cases","offer_id":42585596395562,"sku":"ZLF-6L9-863","price":4000.0,"currency_code":"USD","in_stock":true},{"title":"5 Gallon \/ 5 Gallon Pail","offer_id":42585596428330,"sku":"RTM-2D5-488","price":150.0,"currency_code":"USD","in_stock":true},{"title":"5 Gallon \/ 4 x 5 Gallon Pails","offer_id":42585596461098,"sku":"PKH-5X4-702","price":550.0,"currency_code":"USD","in_stock":true},{"title":"5 Gallon \/ 36 x 5 Gallons (Pallet)","offer_id":42585596493866,"sku":"CFD-7P1-973","price":4700.0,"currency_code":"USD","in_stock":true},{"title":"15 Gallon \/ 15 Gallon Drum","offer_id":42585596526634,"sku":"TSL-3K6-529","price":440.18,"currency_code":"USD","in_stock":true},{"title":"55 Gallon \/ 55 Gallon Drum","offer_id":42585596559402,"sku":"YMW-8A9-644","price":1200.0,"currency_code":"USD","in_stock":true},{"title":"55 Gallon \/ 4 x 55 Gallon Drums","offer_id":42585596592170,"sku":"ZTC-4H1-882","price":4350.0,"currency_code":"USD","in_stock":true},{"title":"275 Gallon \/ 275 Gallon IBC Tote","offer_id":42585596624938,"sku":"LXP-6Q7-435","price":5300.0,"currency_code":"USD","in_stock":true},{"title":"330 Gallon \/ 330 Gallon IBC Tote","offer_id":43829845000234,"sku":"GJD-9M3-711","price":6300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/2734\/1866\/files\/propylene-glycol-tech-30--330--gallon.jpg?v=1764176530","url":"https:\/\/alliance-chemical-store.myshopify.com\/products\/30-propylene-glycol-technical-grade","provider":"Alliance Chemical","version":"1.0","type":"link"}
