^®Antifrogen N

^®Antifrogen L

If no special requirements are stipulated, you should use the ethylene-glycol-based Antifrogen N. It has the better physical properties than Antifrogen L.

Only where the heat transfer medium could come into contact with drinking water or food (e.g. in breweries, dairies, ice-cream factories, cold stores, fish processing factories) Antifrogen L should be preferred, because it is based on the physiologically harmless product 1,2-propylen glycol.

New ^®Antifrogen KF

New ^®Antifrogen SOL

The low-viscosity cooling brine Antifrogen KF, based on organic salts (formates), was developed specially for low-temperature applications below –20 °C in the food sector (e.g. super markets, dairies, ice-cream factories, cold stores, fish processing factories, etc.)

Antifrogen SOL is the recommended medium for solar heating systems subject to high thermal stress, especially for those with evacuated-tube collectors. It has a boiling point of ca. 106°C. Under pressure it can be used at much higher temperatures (up to 260°C).
