Situation without FIRE CURTAINS

Deadly danger!

Smoke flows towards the stalled cars and persons!

The following examples were visualized using a computer simulation (CFD). In fact, however, the function was also demonstrated in a practical test in the currently probably safest tunnel in Roppen (Austria).


After the extraction fans 1 have been turned up to maximum after the onset of the fire, due to the direction of the flow
mostly fresh air is drawn in from the exit portal 2 and
extracted at the extraction port 3 .

Due to the thermal situation, the air before the place of the fire will flow towards the entry portal, so that the cars stalled there and the persons will be in the smoke.

Deadly danger!
