Austria Highway A9, Tunnel Ottsdorf

26 mars 2024

For a joint venture of OESTU STETTIN and VOGL+ we designed and installed a declined wind deflectors in the new and higher tunnel niches which are carrying the bigger tunnel fans to ensure the tunnel can be operated with bidirectional traffic under the refurbishment.

The system is made of suspended stainless steel profiles and a fire resistant panel with open joints. The ventilation test went very well and proofed the function of the whole concept and system.
