Supplied at 100% concentration in a 55-gallon container, it guards against frost damage, internal corrosion, and limescale buildup. At a minimum in-use concentration of 25%, it delivers frost protection down to 12.2 degrees F (-11 degrees C). Increasing the concentration to 50% extends protection down to -29.2 degrees F (-34 degrees C). HVAC technicians and mechanical contractors handling closed-loop fluid systems rely on Alphi-11 as both a seasonal antifreeze and a year-round inhibitor treatment.\u003c\/p\u003e\n\u003cp\u003eAlphi-11 is suited for residential and commercial hydronic heating systems, chilled water loops, and geothermal ground-source heat pump circuits. It is designed to protect ferrous and non-ferrous metals commonly found in closed-loop piping, heat exchangers, and coil assemblies. The 55-gallon drum format is practical for commercial installations, large geothermal projects, or service companies treating multiple systems from a single supply. Dilution to the required working concentration is performed on-site prior to charging the system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombined antifreeze and corrosion inhibitor in a single glycol-based formula\u003c\/li\u003e\n  \u003cli\u003e25% concentration provides frost protection to 12.2 degrees F (-11 degrees C)\u003c\/li\u003e\n  \u003cli\u003e50% concentration provides frost protection to -29.2 degrees F (-34 degrees C)\u003c\/li\u003e\n  \u003cli\u003eProtects against internal corrosion and limescale in closed-loop systems\u003c\/li\u003e\n  \u003cli\u003eCompatible with geothermal, hydronic heating, and chilled water applications\u003c\/li\u003e\n  \u003cli\u003eSupplied at 100% concentration for on-site dilution to required working strength\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in closed-loop hydronic heating systems, chilled water systems, and geothermal ground-source heat pump circuits.

Flush and clean the system before introducing the treated fluid to avoid contaminating the inhibitor package. Dilute to the required working concentration using clean water before charging; do not introduce full-concentration fluid directly into an operating system. Verify concentration after charging using a refractometer or appropriate test kit to confirm frost and corrosion protection levels are within specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVolume\u003c\/strong\u003e: 55 gallons\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConcentration (as supplied)\u003c\/strong\u003e: 100%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Concentration\u003c\/strong\u003e: 25%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrost Protection at 25%\u003c\/strong\u003e: 12.2 degrees F (-11 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrost Protection at 50%\u003c\/strong\u003e: -29.2 degrees F (-34 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFormula Type\u003c\/strong\u003e: Glycol-based antifreeze and inhibitor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 125 pounds\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: FERNOX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 155738-0055\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNOX","offers":[{"title":"Default Title","offer_id":51267900604722,"sku":"155738-0055","price":3398.6,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/fernox-155738-0055-antifreeze-protector-55-gallons","provider":"Voomi Supply","version":"1.0","type":"link"}
