Technical details

Spezifikationen

The Double-Q® is an innovative, horizontal-flow system of the 4.0 generation.

The shielding units are placed at the entrance of buildings and fed by the external ambient air.

No heated or conditioned indoor air is used.

 

Thus, the Double-Q® system is more efficient than a conventional indoor vertical flow air curtain system.

 

The Double-Q® system can subsequently be placed in front of the exterior facade.
