Many applications in the industry require a fluid to transport heat or cold. Those applications range from solar panels or heat
pump systems, over cooling or heating of industrial processes and refrigerants in indirect cooling systems to artificial ski-tracks or ice rinks. This transport medium is usually called secondary refrigerant, brine or secondary coolant. The ideal secondary refrigerant must ensure a good thermal conductivity, have a high specific heat, high density and low viscosity. It is also important that the secondary refrigerant is nonflammable and compatible with common engineering materials.
Zitrec S has been developed specifically for closed indirect cooling systems where low temperatures are predominant. Zitrec S
provides protection against boiling, freezing and corrosion. The required dilution is determined by system requirements, mainly
freezing requirements. Therefore Zitrec S is available in five ready-to-use dilutions: -10°C, -15°C, -25°C, -40°C, and -55°C.
