Antifrogen® N

Antifrogen® N is a liquid, tinted pale yellow, for use as a heat transfer medium in closed hot water heating systems, heat pumps and as cooling brine in industrial refrigeration equipment. Antifrogen® N was developed for use as a heat transfer and refrigerating medium. Its antifreeze action is based on monoethylene glycol, which with its high boiling point of about 198 °C prevents loss by evaporation.

Antifrogen® L 

Antifrogen® L is a clear liquid, tinted blue, for use as a heat transfer medium in heat pump systems and in the food industry, e.g. in breweries, dairies, ice-cream factories, cold stores and fish processing factories.

Antifrogen® L fulfills a dual function as a heat transfer medium. It ensures that the aqueous solution remains liquid at the required brine temperature and protects any metal components in the refrigeration system from corrosion. Its antifreeze action is based on monopropylene glycol, which with its high boiling point of about 187 °C prevents loss by evaporation.

Antifrogen® L can be described by the usual classification as toxicologically harmless.

Antifrogen L is used as a heat transfer medium in heat recovery systems and in the food and pharmaceutical sector or where the possibility of the heat transfer medium entering process water or hot water cannot be excluded.
