It is made of Polypropylene. It consists of capillaries with an external diameter of only 4.3mm and two collection pipes of 20mm. T To heat or cool rooms, hot or cold water runs through the capillary tube mats system to exchange heat with the space air by radiation.� They ensure a quick dissipation of the cooling load or a quick supply of the heat requirement. Due to the large exchange surfaces, large energy quantities can be transmitted with low temperature differences between the active room surface and the room air.
