FOGTEC has designed and tested its state of the art Low Pressure Water Spray System for tunnels with the design complying with the requirements of NFPA 502 and the SOLIT Engineering Guideline.

Full scale fire tests proved the effectiveness of the system for severe HGV fires and have been carried out in compliance with Annex 7 of the SOLIT Guideline. The system consists of corrosion resistant pipework and nozzles, all of stainless steel, for a long lifetime in the tough tunnel environment.

FOGTEC’s well-known remote service section valves allow for highest system availability at lowest maintenance costs and there is no extra intervention in the tunnel for maintenance purposes required.

Low pressure systems are an option especially for shorter tunnels. For longer tunnels, high pressure water mist systems are more favourable due to low water consumption and reduced pipework sizes.

Further information will be published soon.
