Citytunnel, Bregenz/Austria
Municipal sector (ASFINAG)
REQUIREMENTS:
SOLUTION:
Upstream installation of a filterless high-performance separator SYSTEM H-C2 NS 80 l/sec. upstream of the pollutant basin
- Highest level of reliability must be ensured even with high levels of dirt and dust
- Ideally a filterless system, as cleaning and maintenance of filters is difficult in decentralised systems
- In the event of a fire in the tunnel, large quantities of extinguishing water are produced, so the system needs to be dimensioned accordingly
