Zehnder also offers solutions that are suitable for large properties with many rooms and installation on multiple levels. As a result of distribution manifolds with a variable number of connectors, up to twelve pipes can run off from a single distribution manifold. Round tubes ensure that risers lose little pressure and are flexible. Horizontal installation with flat tubes takes up little space and is flexible due to a large number of moulded parts. The layout of the pipes and the positioning of the outlets are also compact and flexible. The ventilation unit and attractive designer grilles meet property developers’ requirement for a cutting-edge design.
