Water Capillary Mats

Capillary mats - energy transfer device in the room

z DSC08375-555-web (106)

Water capillary mats are the key element of the Hydrokapillare system.

The capillary tubes are made from high quality polypropylene (PP-R) – an environmentally friendly and safe plastic with excellent thermal management and elasticity properties.

Diameter of capillary tubes - 3,4 or 4,3 mm

Basic types of capillary mats:

Asset_WK_G20_GB20

Type G

A - distance between capillaries - 10/20/30/40/60 mm;

B - main pipes PP-R d20x2mm, PN10 (at both ends of the capillary mat)

L - length of capillary mat.

Asset_WK_S20_SB20

Type S

A - distance between capillaries - 10/15/20/30 mm

B - main pipes PP-R d20x2mm, PN10 (at one end of the capillary mat)

L - length of capillary mat.

Additional advantages in safety, maintenance and quality:

  • Limestone does not occur in water capillary mats; limestone forms at +60°C – the water in the water capillary mat system is at max. +32°C for heating and at max. +18°C for cooling.
  • Mud does not occur in water capillary mats; mud results from corrosion – the water capillary mat system uses only corrosion-protected components made from PPR, stainless steel, brass or bronze.
  • Prior to operation, the safety of the water capillary system is verified with air pressure at 20 bar and water pressure at 10 bar; the system is filled only once.
  • Water capillary mats can be easily repaired; a capillary is cut and both ends are welded – with no effect to the heating/cooling output.
  • Water capillary mats do not require maintenance and have a safety guarantee of up to 50 years.
