Tunnel Systems

Expertise³ in tunnels

In 2002, AQUASYS was the first company to receive an international accreditation for an automatic, fix installed fire fighting system for tunnels.

Based on many years of experience this solution was continually developed into today's H2O³ system, which is designed to meet the specific requirements of a tunnel fire.

Special conditions

In the case of a fire in a tunnel, structural conditions lead to a rapid increase in temperature and large amounts of smoke, which cannot escape due to the structure of the tunnel. These conditions, difficult to control using conventional methods, endanger a large number of people, vehicles and the tunnel structure itself if they are not quickly contained.

That is why AQUASYS developed rapid fire control (RFC): The specially designed water exposure forms a mist that efficiently contains the fire by extracting energy and displacing oxygen without wasting time. At the same time SAFe (safe approach function extreme) helps or even allows the fire fighters to access the scene by shielding and reflecting the heat radiation of the fire. Cleansing of the smoke gases supports the preservation of the oxygen content in the tunnel environment.

Clear reduction in fire damage

RFC (rapid fire control) interacts against the spread of fire to others vehicles and therefore effectively limits damage. Because tunnels are important infrastructural connections and a quick return to operation is essential to the continuation of traffic, the protection of the tunnel structure is a crucial economic factor. Damage to the ceiling of the tunnel from high temperatures and time-consuming and cost intensive repair work caused by a fire incident is minimised or even completely averted with an AQUASYS H2O³ system.
