“EKOFRITHERM” is a clear liquid, tinted pale red, for use as a cooling brine and heat transfer medium in solar heating and heat pump systems as well as in the food industry (such as breweries, dairies, ice cream factories and fish processing factories). Its antifreeze action is provided by the toxicologically harmless 1.2-propylene glycol. “Ekofritherm”  also contains corrosion inhibitors that protect the metals of the cooling and heating systems, even in combined systems, permanently against corrosion and prevent the formation of boiler scale.  Suitable in use with all standard seal materials.
