Comprehensive and Silent Air Conditioning by Utilising the Natural Capillary Effect

Almost all organisms use liquids for storing and transferring heat when regulating their microclimate. Here the liquid is distributed over a large area by a fine capillary network close to the surface. The efficiency and effectiveness of this biological system has been perfected as part of continuous natural selection. BEKA’s capillary tube heating and cooling system is based on this evolutionary technology and thus enables the most natural form for providing comprehensive indoor air conditioning.

The Reason for BEKA Capillary Tube Mats – Learning from Nature

BEKA’s capillary tube mats are made of pure and highly recyclable polypropylene. The narrow spacing between the thin capillary tubes and the capillary tube mat’s position close to the surface being thermally conditioned ensure uniform surface temperatures with high energy efficiency. This results in very short response times for the cooling and heating surfaces and a very comfortable temperature distribution in the room. The flexibility of the capillary tube technology enables easy installation even in the most diverse structures.

Versatile Applications and Considerable Design Freedom

The narrow dimensions of the capillary tubes with an outer diameter of only 3.35 mm give the capillary tube mats considerable flexibility. A wide range of different capillary tube mat versions enables diverse applications, whether for underfloor heating, wall heating, ceiling heating, chilled ceilings or as surface collectors for utilising geothermal heat. The capillary tube technology is equally suitable for new build-schemes or for modernising existing buildings, irrespective of whether they are residential buildings or high-rise office blocks.

  • Uniform heat distribution
  • Best price-performance ratio

High Specific Outputs and Easy Installation

BEKA capillary tube mats are produced in various structural designs with regard to the capillary tube diameter and spacing between the capillary tubes. An optimum version is therefore available for every ceiling, wall or floor application with regard to achieving high specific cooling and heating capacities and excellent workability. The narrow diameter of the capillary tubes enables the capillary tube mats to be installed very close to the ceiling surface. The thermal resistance from the cooling/heating water up to the surface being thermally conditioned is therefore low, which enables the surface to respond quickly to temperature changes in just a few minutes. Here it is irrelevant that the capillary tubes are made of plastic because the capillary tubes only have 0.5 or 0.8 mm wall thicknesses and therefore hardly contribute to overall thermal resistance. The large number of capillary tubes also provides a very uniform surface temperature that is very close to the average water temperature. Test certificates for standard cooling capacities to EN14240 and standard heating capacities to EN 14037 are available for standard installation situations.

Capillary tube mats can be installed in all standard ceiling structures. The flexibility of the thin capillary tubes even makes it possible to activate curved and arched ceiling shapes.

Maximum Quality Creates Durability

The BEKA capillary tube mats are produced on special machines in strict accordance with quality standards. Every working step in the manufacturing process is monitored and recorded. The polypropylene used is of the best possible quality. The structural dimensions of the BEKA capillary tube mats have been defined with regard to reliability and longevity. Our devotion to providing “gentle” air conditioning with capillary tube mats is reason enough to ensure high quality standards and provide maximum security for our customers with a 15-year warranty for all BEKA capillary tube mats.

The narrow wall thickness of the capillary tubes and the large number of heat conducting tubes ensure more than just good heat transfer. This works excellently even though the capillary tubes are made of plastic, which in itself does not have particularly good heat conducting properties. The capillary tube technology in itself more than compensates for this “disadvantage”. BEKA’s expertise as a producer is clearly evident in the reliably firm and securely welded connections between the capillary tubes and the distribution pipes.
