FreeziumTM


DESCRIPTION

 Freezium - mixed with the appropriate amount of water - is used as a
multipurpose heat transfer fluid based on potassium formate.


APPLICATION

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 rigs.  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 boiling, freezing and corrosion. The dilution is determined by system requirements, mainly freezing requirements. Therefore Freezium is available in four ready-to-use dilutions.

 COMPATIBILITY AND MIXABILITY

Although Freezium is – to some extent – compatible with most alternative heat transfer fluids, 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.  Specifically special care should be taken with calcium chloride, as this can increase significantly the risk of corrosion.

Freezium is compatible with European hard tap waters, but we strongly dissuade you to further dilute Freezium yourselves.  Consult your local Arteco Area Sales Manager for more information. 

It is recommended to avoid using Freezium in installations containing Aluminum, Zinc or galvanized steel.

CORROSION PROTECTION

 Freezium contains an inhibitor package to ensure corrosion protection at both high and low temperature.  Anti-corrosion performance is demonstrated through standard and specific corrosion testing.

STORAGE REQUIREMENTS

 The product should be stored at ambient temperatures and periods of exposure to temperatures above 35°C should be minimized.  Freezium can be stored for minimum 1 year in unopened containers without any effect on the product quality or performance.  It is strongly recommended to use new containers and not recycled ones. 


TOXICITY & SAFETY

For detailed Toxicity and Safety Data we refer to the Material Safety Data Sheet.  Freezium is not toxic and biodegrades quickly. The transport is not regulated.
