Capillary tube mats consist of a multitude of thin, parallel capillary tubes measuring 3.4 x 4.5 mm through which heating or cooling water is being circulated. The capillary tubes and the leads for the capillary tube mats are made of premium-quality polypropylene which makes them highly flexible and durable. Comprehensive durability and material tests have shown an expected longevity of over 50 years. The elements for the heating and cooling surfaces are produced and delivered individually for every room.
The capillary tube system is attached to the supply line by thermal plastic welding or with flexible tubes and plug connections.
