Brief presentation of the project

In Hamburg, a new building stands out among the gray sea of steel and concrete structures: the multifunctional "Wälderhaus" with its "green" wooden facade and space for plants and birds.

Brief presentation of the EconAqua water mist sprinkler system

The low-pressure water mist extinguishing system consumes around 85% less water than conventional sprinklers. In this way, in the event of fire, water damage can be minimized - an important aspect of building with wood construction that suffer considerably higher damage through extinguishing water than reinforced concrete structures, for example. At the same time the quantity of stocked supply can be reduced due to the reduced water consumption. In the case of the Wälderhaus, a small sprinkler control system with a 20 m³ water tank is sufficient. Caverion installed the sprinkler heads throughout the entire building.
