Abstract:
An insulation system for a pipe or a container having a surface temperature which for shorter or longer periods is lower than the dew point temperature of ambient air, and comprising an inner capillary-active slot between a surface of the pipe or the container and a surrounding heat insulation layer in which one or more capillary-active openings are provided which connect an inner side of the insulating layer with an outer side thereof, so that condensed water can be transported by capillary action from the surface of the pipe or the container to the outer side of the insulating layer, from where it can evaporate, said heat insulating layer having a diffusion proof outer side and being surrounded by a water-repellant membrane, so as to form an outer slot between the outer side of the insulating layer and the membrane.
