EconAqua® automatic low-pressure water fog system

House of Oceans, Vienna

Econ-Aqua® automatic low-pressure water fog system for protection against vertical flashoverSchutz vor vertikalen Brandüberschlag

The House of Oceans is an Aqua Terra Zoo known far beyond Austria's borders in the heart of the 6th district, south of the Mariahilfer-Strasse in Vienna. The zoo's special feature is that it has made a World War II flak tower its home. Since its opening in 1957, the house of oceans and its attractions have delighted over 640,000 visitors a year, making it one of the most visited attractions in the city of Vienna.

Thanks to the installed low-pressure water fog extinguishing system EconAqua®, the newly built glass façade on the east side of the building is protected against vertical spread of flames in the event of a fire. Due to the lower water consumption and stronger fogging of the EconAqua®, a fire is fought faster and the building is less damaged than with conventional sprinkler systems. Furthermore, the extinguishing system could be installed in a room in the old building due to the small amount of space required, and the new building could be used unhindered for aquariums, animal enclosures and office space.
