New capillary tube

The capillary tube system is a very progressive radiant heating and cooling system. It can be integrated in nearly all construction elements such as flooring, walls or ceilings. The system basically consists of capillary tube mats, which enables a heat transfer through a very large surface compared to conventional under floor heating or heating element system.
The heat emission during the heating mode supplies a comfortable radiant heat and the heat absorption in the cooling mode supplies an effective and comfortable silent cooling without any noise, draught or dust. Compared to air conditioning units the energy consumption for cooling with capillary tube mats is very low.


The capillary tube mats are harp-shaped and made of many single capillary tubes, which run parallel and extra narrow to each other and end up in a main pipe.
This technology follows biology, where the spreading of energy in our body is done with a large network out of an immense number of thin capillaries. The whole mat consists of pure Polypropylene. Polypropylene (PP) is easy to handle and compared to composite material, which is often used for conventional radiant heating systems, the production of PP shows the better balance of embodied energy. Furthermore the synthetic material makes the capillary tubes very flexible, lightweight and cause of the very small diameter of the capillary tubes, the capillary tube mat has a thickness of 5 mm only. That is why the capillary tube system is suited especially for retrofitting of buildings.

The use of this allows us to have a great exchange surface and create a comfort by not only having the indoor air at the desired temperature, but also having comfort due to the radiant temperature of the ceiling, since the temperature of ceiling is controlled for conditioning the zone. This enables a great exchange surface, what let us to work with lower heat transfer fluid temperatures, and thus greater efficiency in the heat pumps. The implementation of such a system implies a greater investment, but lower operation costs in energy and economics, what implies savings and so at long-term it is also cost effective.
