Description:

NuTherm™ HC-20 is a high-performance heat transfer fluid designed as an alternative to less effective glycol, PAG, and Calcium Chloride open bath fluids. NuTherm HC-20 is non-toxic, non-flammable, and has a robust corrosion inhibition package making it ideal for use in closed systems down to -20°C (-4°F) and up to 218°C (425°F).

NuTherm HC-20 has superior thermophysical properties in comparison to traditional closed system heat transfer fluids, including higher thermal conductivity and specific heat, as well as lower viscosity, making it an extraordinarily more efficient closed system coolant within its operational temperature range. NuTherm HC-20 is non-hazardous, biodegradable, CFC-free, antimicrobial, and has exceptional thermal stability at high temperatures in comparison to glycols, PAG’s, Calcium Chloride, Trichloroethylene and Methylene Chloride (Dichloromethane) making it an intelligent alternative. NuTherm HC-20 is formulated with a incredibly robust and efficient corrosion inhibition package, allowing the product to be used on most metals including Stainless Steel, Carbon Steel, Cast Steel, Copper and its alloys (Brass & Bronze), Monel, Nickel, Hastelloy, Inconel, Tantalum, Titanium, Titanium alloys (Ti6Al4V), Aluminium and Cast Iron. Do not use on Zinc, Zinc-plated or galvanized metals, Magnesium. NuTherm HC-20 corrosion tests at 80°C show incredible results of x mmpy (x mpy) on C260 Brass alloys, x mmpy (x mpy) on 304L Stainless Steel, and x mmpy (x mpy) on AL1100 Aluminium. NuThem HC-20 does not produce pitting corrosion on Aluminium alloys like other Potassium Formate open bath heat transfer fluids.

*mmpy = millimeters per year; mpy = mils per year (1 mil = 0.001 inch); In general, uniform corrosion rates less than 2 mpy are acceptable for most applications. Corrosion rates between 2 and 10 mpy are considered marginal and may impact useful life of the equipment. Corrosion rates greater than 10 Mils per year are unacceptable.
