Cooling fluids

The heat carrier - the liquid or gaseous substance applied to transfer to thermal energy. In prac-tice most often use water (in a condition of gas or liquid), air, freon, nitrogen (including liquid), glycerin, petroleum oils, is more rare fusions of some metals.


The heat carriers are used in major units and engineering systems that serve to transport and/or distribute heat:

- building heating systems,

- low and medium temperature storage systems,

- conditioning systems,

- oil heaters,

- heating units,

- boiler stations,

- solar collectors and water heaters,

- cooling fluids (antifreeze substance) for combustion engines.

Working temperature range

There is no heat carrier that is capable to cover the whole range from 0 to 3000 K, for example. Every heat carrier has its own working range and there is a range within which the coolant may op-erate for some time without significant decomposition.

Cooling liquids (anti-freezing agents) are specific cases of heat carriers.

Corrosive activity limits application of some coolants, structural materials and forces to add cor-rosion inhibitors. A classical example is glycolic anti-freezing substance for combustion engines.

The company has an allocated storage premises where the most demanded cooling liquids and other materials are formed to fulfil repair of combustion engines and air conditioning works, instal-lation of ventilation, heating, water supply and water treatment.
