We have the Tunnel Vision.

The rapidly increasing amount of traffic worldwide turns tunnels into perilous needle eyes. The safety concepts of such installations, and also the ventilation and smoke exhaust system as a vital component thereof, are coming more and more into the focus of public interest.

Both for longitudinal or cross-ventilation concepts, WOLTER offers special made-to-measure equipment for road and metro tunnels, which are tested and certified up to temperature class F400 according to EN 12101-3. Different grades of stainless steel can be used for the higher demands of the corrosive and abrasive atmospherical conditions in tunnels, to ensure a long-lasting, reliable function for normal ventilation and emergency operation.
