Antifrogen GEO was developed for the application in near-surface geothermal systems and offers long-lasting protection against frost, corrosion and limescale. The product is physiologically harmless and meets our standards for sustainability and responsible action.

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