Not only capillary mats, but the entire capillary system requires considerably less space than conventional systems.

This becomes obvious when comparisons are made with conventional ventilation and air conditioning systems.

To carry a power of 10 KW, an air conditioning unit requires an air duct with dimensions of 530×400 mm (with dT 8K at 5 m/s).

Since water is much more ideal for transporting energy, capillary systems only require a DN 50 PP pipe (dext = 63 mm) to transport the same power.
