Antifreeze / Heat transfer liquid

The heat transfer fluid is a liquid or gas that runs inside the primary circuit of the solar installation that when passes the collector it’s able to heat absorbing the energy from the sun. In the heat exchange, this energy will go through the secondary circuit of the solar thermal installation to get profit from it.

The absorbing ability and giving heat comes determined by a characteristic called specific heat. The heat transfer liquids commonly used are: water, water and antifreeze mixture, synthetic organic liquids and silicon oils.

The heat transfer fluid is indispensable to avoid frostbites and also has to be able to resist high temperatures.

It’s very important to choose a suitable heat transfer fluid to obtain the maximum energetic efficiency of the installation.
