Antifrogen® N

Heat Transfer Fluid

Edition Date :
August 09, 2022

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 is not suitable for the use in food or pharmaceutical applications. Alternatively, the use of Antifrogen® L is recommended. The product is inhibited without the use of nitrites-, amines-, borates-, silicates- and phosphates. The optimization of the corrosion inhibition system was performed without the use of CMR-substances (cancerogenic, mutagenic, reprotoxic).

Benefits

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.
The frost resistance of the mixture does not change even after many years use, provided the Antifrogen® N concentration remains constant. Furthermore phase separation of Antifrogen® N/water mixtures does not occur.

Service and Monitoring

According to our experience Antifrogen® N can be used in installations for many years. However, the Antifrogen® N concentration in the installation should be checked annually. This check is also advisable when the installation is topped up with liquid. Distributors have Antifrogen® N antifreeze testers for this purpose.
The performance of the Antifrogen® N/water mixture should also be checked at intervals of one to two years. If a 250 ml sample is provided, the distributors can also perform this service.
