SEM-SAFE® high-pressure water mist system To protect the Alsion building, a SEM-SAFE® high-pressure pump unit was used. The type of nozzle used is our CEN nozzle with a 5.5 metres spacing at a height of 3 metres and a nominal release temperature of 57°C. Torben Sten Hansen from the Danish consulting engineering firm Sloth Møller states: “The water mist system fits well with the innovative “spirit” characterising the project. There are many reasons as to why water mist was chosen over a traditional sprinkler system. A total of 2,200 nozzles were installed: • 2,000 closed nozzles (wet system) – offices, corridors, restaurants, classrooms, etc. • 200 open nozzles (dry system) – atrium, concert hall, etc. First of all, the system is much more flexible to incorporate than the sprinkler system. It requires less space as the pipes are smaller. This makes it easier to incorporate the pipes in a way that makes them less conspicuous. The actual nozzle is also smaller than the traditional sprinkler nozzle and is therefore less conspicuous when mounted in the ceiling. In other words, a water mist fire protection system is more aesthetic and thus preferred by most architects. Another strong argument is that the solution is very economical. The water volume used in a fire situation is less than ten per cent of the volume used when a sprinkler system is activated. This means that a lot of water is saved. But what is more important is to limit the damage caused by the fire, which is the whole concept behind water mist. The water mist is good for cooling down glass. It acts as a sort of “water film” which quickly spreads over even large glass surfaces, cooling them down.” The vision is to make a close connection between Research Park, university and culture by creating innovative and unique solutions. High-pressure water mist is the direct result is a direct result of this vision. It is an innovative and effective method for fire fighting in buildings.
