TUNNELS
WHY CHOOSING ONE SEVEN?
- One Seven® does not only control the fire but suppress it very efficiently
- Strong cooling capacities (adhesive to the surrounding surfaces)
- Direct attack of the fire seat (high kinetic energy – adhesive property)
- One Seven® can be transported very rapidly over long distances with low pressure loss
- One Seven® is very efficient on hydrocarbons or tyres fires
- One Seven® quality is independant from the surrounding air quality (compressed gaz)
- One Seven® efficiency is not hampered by the ventilation (tested with more than 6m/sec)
- One Seven® discharge inside the tunnel entails no risk for tunnel users
- One Seven® discharge inside the tunnel does not hamper the users evacuation
- One Seven® protects the tunnel structures against heat radiation
- One Seven® does not hamper the firefighters intervention
- One Seven® can be discharged through fixed nozzles and/or through hose lines
- One Seven® reduces water supply constraints
- One Seven® maintenance in tunnels is easy and fast (dry deluge system: no frost, no corrosion)
ONE SEVEN® EXTINGUISHES A 150mW FIRE WITHIN LESS THAN 17 MINUTES
