Production. All greata capillary tube mats are made in china from high quality polypropylene. Constantly further developed production machines and a unique welding technology for connecting the capillary tube with the mat distributor pipes ensure a very high quality standard and allow a long-term guarantee.
A capillary tube mat is similar to the human blood circulation:
The total mass flow is divided into parallel fluid flows in the capillaries. The flow velocity in the arteries and in the capillary tubes is around 0,05 m/s up to 0,2 m/s. For cooling or heating spaces cold or warm water flows through the capillary tubes with an outer diameter of 3,4 or 4,3 mm.
For the production of Greata capillary tube mats (CTM), pipes, supply + return lines we use only high-quality Polypropylen-Random-Copolymerisat (PP-R), DIN EN ISO 19069-1.
In order to provide an ideal capillary tube mat for each application, the Greata team in China has been researching and developing since the 2014s. The currently available capillary tube mats differ in terms of diameter & distance of the capillary tubes, mat shape, diameter and position of the mat distributor pipes, as well as in terms of the carrier material. Moreover various conncections are also available.
