HEAT TRANSFER FLUIDS

FREEZIUM™

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 or secondary coolant. The ideal secondary refrigerant must ensure a good thermal conductivity; have a high specific heat and low viscosity. Freezium™

remains completely fluid even if the pipe work is frozen. It is also important that the secondary refrigerant is non-flammable and compatible with common engineering materials.

Freezium™has been developed specifically for indirect cooling systems and heat pumps. Freezium™  provides protection against freezing and corrosion. The dilution is determined by system requirements, mainly freezing requirements

Exclusive use of Freezium is recommended for optimal corrosion protection. Mixing with other heat transfer fluids may lead to some precipitation of solid material, causing problems in systems by clogging or damaging pumps, and by increasing the risk of corrosion. In-house testing has confirmed that topping- up Zitrec S installations with Freezium up to 10% gives no incompatibility issues. Contact your local area sales manager for more information or specific questions.Freezium -60°C is provided as ready-to-use product. Freezium -60°C can be diluted with water up to a freezing point of -30°C. In applications where no corrosion protection is required (f.e. plastic pipes), Freezium -60°C might be diluted further.
For optimal performance and controlled quality, we advise the use of deionised or distilled water to prepare the ready-to-use dilutions. We refer to our product information leaflet on water quality recommendations. We advise against the use of Freezium in installations containing aluminum, zinc or galvanized steel.
