High-Pessure Water Mist for Reliable Operational Safety
High-Pessure Water Mist for Reliable Operational Safety
Cable Tunnels contain important power and data cables. However, they are rarely fitted with a firefighting system. If a fire breaks out in a cable tunnel, there is a risk of significant operational disruption or even a complete failure. Reliable fire protection is therefore crucial in order to prevent expensive consequential damage.
pre-warning times requirement assures safe environment for people and minimal fire damage thus business interruption
cooling effect compared to any other firefighting agent assures safe environment for people and effectively avoids re-ignitions
Using high-pressure water mist offers a safe and technically efficient fire protection solution for cable tunnels. The fine mist effectively fights fires while minimising consequential damage. High-pressure water mist systems therefore significantly increase the availability and reliability of installed cables.
FOGTEC’s high-pressure water mist fire protection system is particularly suitable for retrofitting thanks to its simple integration and low space requirements. It can also replace or supplement complex, restrictive structural measures such as fire walls.
High-pressure water mist therefore provides a practical and safe fire protection solution for cable tunnels.
FAQ – Fire Protection in Utility & Cable Tunnels
What is high-pressure water mist and how does it extinguish fires?
Fine water mist cools the fire rapidly and locally displaces oxygen, effectively extinguishing flames with minimal water and reducing collateral damage.
Does it reliably protect cable trays?
Yes — large-scale tests and project experience demonstrate effective fire suppression and prevention of re-ignition. System design must consider tray cross-section, ventilation, and cable layout.
Is water mist suitable for retrofitting instead of structural measures?
Often yes: water mist systems are space-efficient and can supplement or replace extensive structural fire protection. Final approval must be coordinated with authorities and experts.
Does water mist damage cables/electronics and how demanding is maintenance?
Lower water usage than sprinklers reduces water-related risks, but moisture can affect electronics. Proper nozzle placement, water treatment, drainage, and regular maintenance are essential.
