FREEZIUM™ -60C


Applications
  • Refrigeration

Product Description

Freezium™ is a secondary coolant developed specifically for use in indirect cooling systems and heat pumps. Freezium, based on a solution of potassium formate (HCOOK) - an organic salt - has been modelled to possess all the properties of the ideal secondary refrigerant: low viscosity, good thermal conductivity, and high specific heat capacity. Unlike conventionally used coolants, Freezium is neither toxic nor flammable. And it biodegrades quickly if ever released into the environment.

All heat exchange and other facilities where Freezium will be used must be designed, built, cleaned and taken into use by professional personnel specialized in the application. Please consult local expert companies.

Handling Precautions

The properties of Freezium depend on the concentration. Freezium is commercially available as a grade having the freezing point of -60°C. Other grades can be produced by diluting (see table below). Note however that other physical properties change with concentration as well and after diluting you need to remember to adjust the Kemcorn inhibitor amount as well.

Freezium is perfectly compatible with most common engineering materials in a wide temperature range including copper, stainless and carbon steel, and user-friendly plastics.

The materials to avoid are aluminium, zinc and galvanized steel. Use of cast iron should be restricted to cool parts of the system.
