The Klix-Kühlrohr-180 ceiling radiator is conceived to provide passive heating and cooling in halls and offices. The extruded aluminium profile comes with an anodised or lacquered surface. The design’s main feature is the groove for a non-drip condensate drain off at water temperatures down to 1 degree Celsius. This allows the available cooling temperatures from geothermal and ice storage systems to be used more efficiently.
