ALD The ALD (former ALD-R 160) is equipped for all purposes. Three volume flows can be set by means of a reduction orifice. Thus, different room sizes with different air requirements can be optimally and comfortably ventilated by the ALD. A staggered arrangement of multi-surface sound absorber modules has proven to be the most efficient variant. Comfort with outer wall air vents The comfort in living spaces depends to a large extent on the positioning and condition of the outer wall air vents. The ALD is therefore equipped with wind pressure protection and a flow-optimised cover to allow draught-free, diffuse air inflow. Nevertheless, careful planning of the installation position is required. If the incoming air is heated as quickly as possible and outside the occupied zone, the risk of draughts is eliminated. Therefore, an optimal arrangement of the ALD in relation to the heating surfaces is necessary.
