Citytunnel, Bregenz/Austria

REQUIREMENTS:

• 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

SOLUTION:
Upstream installation of a filterless high-performance separator SYSTEM H-C2 NS 80 l/sec. upstream of the pollutant basin
