Tunnels are important lifelines in each economic area; millions of people worldwide use tunnels for road traffi c as well as for rail traf-fi c every day. Due to the immense constructi on costs and the com-mercial and economic relevance of such tunnels, fi re protecti on is important to ensure the safety of people as well as buildings, and a

highly effi cient and reliable fi re protecti on system is required. The installati on of a high pressure water mist system not only ensures a prompt response, less damage and reduced downti me for a tun-nel, but also the usability of escape routes and access for the fi re brigade.

As a leading manufacturer of modern high pressure water mist sys-tems, we carry out fundamental research as a basis for the conti -nuous improvement of our technology. Our R&D process is based on well known traditi onal fi re engineering accompanied by com-plex CFD simulati ons and validated by full scale fi re testi ng. The

interacti on between results gained from scienti fi c models and em-pirical values derived from full scale fi re tests enables us to acquire scienti fi c experti se for the improvement of simulati on models, as well as to design fi re tests with opti mum benefi t for the develop-ment of water mist systems and hence for the benefi t of our clients.

MONA LISA TUNNEL

ØRESUND TUNNELThe 12 km long tunnel and bridge constructi on through the Øre-sund Strait connects Denmark and Sweden and is used daily by 17,000 motor vehicles and 200 trains. In additi on, power and data lines are carried in a separate, dedicated tunnel, making the Øre-sund link an essenti al lifeline of this economic region in the Balti c.

A 4 km long secti on of this link is routed in tunnels under the sea. To ensure its constant availability, this technologically vital energy and data tunnel is protected with an AQUASYS high pressure water mist system.

This 850 m long inner-city tunnel is an important transport link to Linz‘s industrial zone. It runs directly under the main east-west rail-way line and a tramway line. An AQUASYS water mist fi re fi ghti ng system ensures a high level of safety and availability of the road

tunnel for the 22,000 vehicles that use it every day and, in parti -cular, guarantees the unhindered use of the railway lines running above even in the event of fi re in the tunnel.

The Felbertauern tunnel is one of the most important north-sou-th road links in the Alps. The elevati on at 1650 m above sea level and length of 5.3 km places special demands on the AQUASYS fi re fi ghti ng system used. As well as having to functi on reliably at

temperatures well below zero, the system must have a high availa-bility, since any closure (however infrequent) of the toll connecti on between the provinces of Salzburg and East Tyrol requires extensive traffi c diversions.

Both tunnels are located on the A73 motorway and are part of the important transport artery for both private and commercial road traffi c between Germany and the Netherlands. Due to the high pro-porti on of heavy and hazardous goods traffi c, the two tunnels were equipped with state of the art safety equipment. The heart of the

safety system is the AQUASYS high pressure water mist system for fi ghti ng solid substance fi res, as well as liquid fi res resulti ng from accidents involving hazardous goods vehicles with an expected heat release rate of up to 200 MW

The City Tunnel in Bregenz directly connects the A14 motorway with the city area and is the fi rst tunnel operated by Austrian mo-torway and express road operator ASFINAG to be equipped with a high pressure water mist fi re fi ghti ng system. The AQUASYS system ensures the three safety objecti ves set by ASFINAG are met: Building protecti on for the tunnel Maximum protecti on for people in an emergency Support for emergency services in the event of a fi re

Due to the design of the AQUASYS high pressure water mist system, its installati on required only one lane to be closed. This also means that the tunnel will not have to be closed for future maintenance work or during exercises by the emergency services.

With 80,000 vehicles passing through it each day, the Liefering twin-tube tunnel in the city of Salzburg is one of the most heavily used tunnels in Austria, as well as being an important transport hub. In additi on to the three carriageways, the tunnel has a motorway juncti on in each directi on. To reduce the signifi cant risk potenti al

resulti ng from this road layout, tunnel operator ASFINAG decided to install an AQUASYS high pressure water mist fi re fi ghti ng system. This system protects both the tunnel tubes as well as the entran-ces and exits. Triggered as soon as a fi re is detected, it eff ecti vely protects both the tunnel infrastructure and the city streets above.

Measuring 14 km in length, the Arlberg tunnel is Austria‘s longest road tunnel and the longest tunnel in the world to be equipped with a water mist fi re fi ghti ng system. The only reliable winter connec-ti on between the provinces of Tyrol and Vorarlberg is protected by 24,000 water mist nozzles, which are fed from the two pump rooms

and water tanks at the tunnel portals. An Aquasys HPWM system was chosen due to the hydraulic requirements resulti ng from the tunnel‘s length and to provide eff ecti ve, reliable protecti on of the escape and rescue routes, which are located in the supply air duct directly above the roadway.

London Heathrow (LHR) is one of Europe‘s largest airports. The airport‘s passenger terminals and central area are accessed via tun-nels located under the runways. The uninterrupted availability of the access tunnel and the runways above them is naturally vital for

airport operati ons. As soon as a fi re is detected, the AQUASYS water mist fi re fi ghti ng system ensures that it is exti nguished and the tun-nel infrastructure cooled to prevent the fi re from causing structural damage, thereby ensuring conti nued operati on of the runways.
