The capillary mats contain capillary tubes which are extremely thin thus providing a great thermodynamic advantage over similar systems with thicker and larger tubes.
Because the Capillary Tubes are so close together (3/8" inches apart) the ceiling temperature remains even. The capacity is limited by the dew point temperature. |

| Higher ripples or oscillations mean then less cooling capacity. |

The illustration above shows the temperature of the chilled water in the capillary tube system is about the same as the mean ceiling temperature.
Despite their smaller diameter, capillary mats experience very little loss of pressure. The water in a capillary mat system runs through many parallel capillary tubes, rather than running through just one tube, as in a system with thicker tubes. The typical velocity of flow with the capillary tubes averages only 10 to 20 cm/second or 4" to 8" inches/second. The velocity in the capillary tubes is always laminar. This has the positive side effect that the loss of pressure in the capillary mats grows linear with the amount of extra water and not quadratic. |

Illustration Below:
Capillary tube cooling can be switched on quickly. After a few minutes, the capillary ceiling begins to cool the room effectively. This is brought about by the very small amount of water in the capillary tubes and the positioning of the mats close to the surface. In addition, the capillary ceiling is able to regulate itself easily. The illustration below shows how quickly the temperature changes. |
