FREEZIUM, Potassium Formate

Refrigerants based on organic salts are a relatively new class of industrial antifreezes.

The most promising representative of such organic salts is potassium formate.

Aqueous solutions of potassium formate have a large number of advantages:

  • low viscosity;
  • high thermal conductivity;
  • non-toxic;
  • biodegradability.


As a result of this set of characteristics, potassium formate-based coolants have become an excellent solution for systems with operating temperatures below -30°C, where glycol-based coolants can no longer circulate or are still pumped, but with great difficulty.

Properties and uses of potassium formate

Freezium is a secondary circuit coolant developed by one of Europe's leading chemical companies specifically for use in modern indirect cooling systems.

Freezium based on potassium formate solution has all the properties of an ideal secondary refrigerant: low viscosity, good thermal conductivity and high specific heat.

When working with Freezium fluid, certain restrictions must be observed regarding temperature conditions and materials used. A more detailed description can be found on the Freezium page.

Freezium's price corresponds to its high thermophysical properties. However, this pays off in full in reducing plant energy costs due to the efficiency of the Freezium fluid in the circuit.

Non-toxic, non-flammable, and about 10 times more biodegradable than glycols,

Freezium does not require any special environmental precautions.

Freezium and potassium formate solutions are classified as non-hazardous cargo for transport.
