FOGTEC Rail Systems high-pressure water mist systems stand out for their particularly effective cooling performance. To fight a fire, the extinguishing medium is atomised at high pressure throughout the hazard area, using special nozzles.
Thus, energy is rapidly extracted from the fire by the enormous surface that is formed by the huge number of very small droplets. These systems can be used e.g. to protect driver cabins, low and high-voltage switch cabinets, equipment boxes, diesel units in underfloor or engine compartments, or to protect generator sets. Special advantages are featured by the FOGTEC Rail Systems high-pressure water mist systems for the protection of passenger compartments since no pre-warning times need to be observed in contrast to gas extinguishing systems, and open doors or windows would be no obstacles to successful fire fighting.
The suitability of the system as a compensatory measure has been proved by independent institutions in extensive investigations comprising a large number of 1:1 burning tests. In case of rail vehicles of higher fire protection classes, the systems allow to replace fire protection doors, to reduce material requirements or to simplify the verification management (e.g. calculation of stability during the blazing fire phase). Owing to the small installation dimensions and the small piping diameters, expenses will be reduced to a minimum, also in case of retrofitting measures,.
Since only very small amounts of extinguishing medium are consumed, space requirements and weight are particularly low. The systems are ideally suited for being integrated in rail vehicles. Low life cycle costs and high reliability are characteristic features of the systems.
The strong cooling effect serves not only for suppressing the fire, but also for protecting men and material from the consequences of an initial fire event. The purpose, in this case, is to protect the immediate surroundings in such a manner that people are in a position to reach the nearest evacuation point, thus ensuring their safe evacuation.
