GLYC module

The program calculates the physical properties as a function of temperature and composition or the frost resistance of

  • ®Antifrogen N (ethylene glycol-water mixtures)
  • ®Antifrogen L (1,2-propylene glycol-water mixtures)
  • ®Antifrogen L (Aqueous solution of organic salts (formates))

as well as the physical properties as a function of the temperature of

  • ®Antifrogen SOL (propylene glycol mixed with higher boiling alkylene glycols).
    This should be used undiluted and has a frost resistance of -27 °C.

The following properties are calculated

Recommendations

®Antifrogen N

If no special requirements are made, the ethylene glycol-based Antifrogen N should be used instead of Antifrogen L due to its better physical properties.


®Antifrogen L

Antifrogen L based on the physiologically safe 1,2-propylene glycol should be used in apparatus in which the heat transfer medium could come into contact with drinking water or food (e.g. breweries, dairies, ice cream factories, deep-freeze chains, fish processing factories, etc.).


®Antifrogen KF

The low viscosity Antifrogen KF cooling sole is used especially for low-temperature systems below -20 °C in the food and luxury food sector, e.g. in supermarkets, dairies, ice cream factories, deep-freeze chains, fish processing factories, etc. The low viscosity Antifrogen KF cooling sole is used for the production of food, beverages and tobacco.


®Antifrogen SOL

Antifrogen SOL should be used in solar systems with high thermal loads, especially with vacuum tube collectors. Antifrogen SOL has a boiling point of approx. 106 °C. However, it can be used under pressure at much higher temperatures (up to 260°C).
