It provides freeze protection down to -60 degrees F and burst protection down to -100 degrees F, making it suited for systems exposed to severe cold. The fluid carries a specific gravity of 1.02 and a boiling point of 113 degrees C, supporting stable operation across a wide temperature range. Licensed HVAC technicians, plumbers, and solar system installers specify this fluid where aluminum, brass, cast iron, copper, and stainless steel components are present in the same circuit.\u003c\/p\u003e\n\u003cp\u003eThis fluid is appropriate for residential and light commercial hydronic heating systems, radiant floor loops, chilled water cooling circuits, boilers, and solar thermal collectors. Solar systems are particularly susceptible to extreme temperature swings, and the inhibitor package in rhogard 5 is designed to address both high-heat degradation and hard-freeze conditions that occur in those applications. The 5-gallon container size suits service calls and seasonal system fills where bulk volume is needed without overage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFreeze protection to -60 degrees F and burst protection to -100 degrees F\u003c\/li\u003e\n  \u003cli\u003eMulti-metal corrosion inhibitor package protects aluminum, brass, cast iron, copper, and stainless steel\u003c\/li\u003e\n  \u003cli\u003eHelps control scale and sludge buildup on heat-exchange surfaces to maintain system efficiency\u003c\/li\u003e\n  \u003cli\u003ePropylene glycol base is non-hazardous and environmentally friendly\u003c\/li\u003e\n  \u003cli\u003ePresto Brilliant Blue dye aids in leak detection during service\u003c\/li\u003e\n  \u003cli\u003eTemperature rating up to 400 degrees F supports high-output boiler and solar collector applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eFormulated for use in fluid systems, hydronic heating and cooling circuits, solar thermal systems, and boilers.

Isolate and de-pressurize the system before draining or adding fluid, and verify the existing fluid type before mixing. Use the appropriate dilution ratio for the target freeze protection level based on system volume calculations. Dispose of spent glycol fluid in accordance with local environmental regulations, as disposal requirements vary by jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Multi-Metal Propylene Glycol Antifreeze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFreeze Protection\u003c\/strong\u003e: -60 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBurst Protection\u003c\/strong\u003e: -100 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoiling Point\u003c\/strong\u003e: 113 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFreezing Point\u003c\/strong\u003e: -50 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlash Point\u003c\/strong\u003e: 104 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecific Gravity\u003c\/strong\u003e: 1.02\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEvaporation Rate\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComposition\u003c\/strong\u003e: Propylene Glycol, Alkaline, Water, Alkalinity Booster, Presto Brilliant Blue Dye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 5 Gallon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHazard Status\u003c\/strong\u003e: Non-Hazardous\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RHOMAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: rhogard 5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RHOMAR","offers":[{"title":"Default Title","offer_id":51468041584946,"sku":"RHOGARD 5","price":165.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313946385.jpg?v=1783913244","url":"https:\/\/voomisupply.com\/products\/rhomar-rhogard-5-hydronic-antifreeze-5-gallon","provider":"Voomi Supply","version":"1.0","type":"link"}
