Environmental protection

The temperature control of surfaces with capillary tube mats, is much more efficient compared with conventional tube systems, due to the small capillary tube clearance of 10 and 15 mm, respectively, and the large surface.

This leads to an optimum energy transfer to the room.Consequently, only very small spreadings between the water temperature and the room temperature are necessary.

Further energy savings result from the fact, that the room temperature as perceived by the
user with the use of radiation cooling and radiation heating, is about 2 to 3°C lower or higher, respectively, than the actual room air temperature.

Significant energy savings when using capillary tube systems, are evident here also.

For example, energy saving for a cooling ceiling with displacement ventilation, can amount up to 40% compared with an “air‐only‐system”.

Furthermore, the production of capillary tube mats, is absolutely pollutant‐free. No contaminated exhaust air or contaminated waste water results in the process. All production waste can be 100% recycled and used again.

The production of polypropylene requires considerably less amounts of primary energy, compared with other materials. Metals require 5 ½ times more, and aluminium even 8 times more primary energy.

As can be seen from the following figures of comparison, the environmental pollution, during the production of polypropylene, is significantly lower -compared with metals.

Pollution values during production of polypropylene compared with metals:

During the selective dismantling of buildings, capillary tube mats can be conveniently removed and recycled, to a high value result; subsequently, they meet the basic demands of the Recycling Economy Law, which is applicable since 1996.

No environment‐relevant pollutants occur, when polypropylene is burnt -because polypropylene is built up on carbon and hydrogen atoms. Particularly, where fires are involved, there are no toxic combustion products, which could lead to permanent injurious effects for humans and animals, as well as to high costs, for the decontamination of buildings.
