Antifreeze, ANTIFROGEN L 43% (-25 ° C), 30 l / 31.5 kg

ANTIFROGEN-L, heat exchanger antifreeze for the food industry, usable from -25 ° C to + 150 ° C (short time to + 80 ° C), for heating and solar systems, heat recovery pump medium, medium for automatic spray systems, liquid for geothermal wells

The minimum concentration (dilution) for adequate corrosion protection is 25% (at this concentration the frost resistance of the mixture is guaranteed to -10 ° C). Antifrogen® L must always be diluted with water before use.
