The hybrid-doweltreeslab (HYB-D) COOL II is composed of the concrete level above and the solid wood dippel trees and cooling elements below. A number of doweltrees are installed, and Abaton cooling elements are placed between the groups of doweltrees. The Hybrid-Doweltreeslab COOL II can be stretched up to 9.00 m with an element width of up to 3.00 m. The specially formulated porous mortar can quickly and hygienically absorb and buffer the moisture inside the panels. This makes it possible to stay below the dew point.
