Condensation in caves, tunnels, etc. underground

Metro - underground in Stockholm treated with KefaTherm Metro - underground in Stockholm treated with KefaTherm

In underground caves and tunnels there are usually big problems with moisture and condensation which causes dripping with water, which can be of great harm to people and materials.

KefaTherm consists of a unique micro-pore matrix which is capable of storing water during the condensation cycle, but ejecting it back into the atmosphere as soon as the temperature is above dew point. KefaTherm is built up of millions of micro-pores of sizes 0.1 - 100 microns.

The micro-pore matrix of 1 mm thick KefaTherm makes the relative surface 20 000 times larger than the two-dimensional surface. This ejection, or evaporation, is done 2 - 3 times more rapidly and efficiently than would be the case from an un-coated surface. KefaTherm is now dry and ready for next condensation period and it works forever.

A coat of 1 mm KefaTherm absorbs and holds up to 535 ml of water per square meter.

The pictures are from the Metro in Stockholm, Sweden.
