Advantages Capillary Tube Mats System

• Energy efficient
  Water supplied in capillary tube mats only requires 28-32℃ for heating purpose, it reduce heating energy consumption compared with the 45-60℃ request of common floor heating pipes. It has tested the capillary system can save 30-40% consumption.
  For cooling in summer, the supply water is around 16-18℃ which is much higher than the traditional air conditioner.
  It can save 50-60% energy consumption. The combination of capillary tube mats with heat pump can achieved the highest outputs.
• Space saving & Easy installation
  Within the construction, the thin capillary tubes mats with an outer diameter of 4.3 mm only be covered with leveling or sealing compound of 10mm thickness.
  The high flexibility of the greata capillary tube mats technology enables easy installation even in the most diverse structures.
• long life & Free maintenance
  All greata capillary tube mats are produced under strict quality control with a top level of precision and safety. No maintenance required with high quality the using life of capillary mat is around 50 years
• Environment friendly
  The raw material is Polypropylene- high quality, environmentally friendly and safe plastic with excellent physical characteristics and highly recyclable.
• Rapid reacting
  The limited thickness minimizes the thermal resistance and leads to the heating reacting rapidly to temperature changes in just a few minutes and achieving high specific heating capacities.

• Healthy & Comfortable
  Greata capillary mats realizes the heat exchange in a form of radiation with gentle and even temperature changes,draughtfree and noiseless.
• Various Energy Solution
  Greata capillary tube mats can be connected with air source heat pump, water source heat pump, ground source heat pump, solar energy, etc.
