Fire Fighting Systems

Rail Systems

The installation of fire fighting systems has been proved to bring about a significant reduction in direct and indirect losses. Safety levels can be greatly improved for both operators and customers. In the long term this has a positive impact on rolling stock availability and on the company balance sheet.

Depending on the risk levels involved, the requirements in terms of fire protection and the installation space available, FOGTEC can offer a range of fire fighting technologies, in particular FOGTEC high pressure water mist and nitrogen systems.

To prove their suitability, most systems are subjected to full-scale fire tests in the FOGTEC laboratories.

Water Mist Systems

FOGTEC high pressure water mist systems are characterised by their highly efficient cooling effect. In case of fire, the extinguishing agent is atomised to a fine mist by being forced at high pressure through special nozzles in the affected area. The huge surface area of the innumerable tiny droplets is able to quickly absorb energy from the fire.

The systems can be used, for example, to protect drivers cabs, low and high voltage switchgear cabinets, control boxes and diesel units in underfloor areas or engine cavities or to protect generators.

FOGTEC high pressure water mist systems offer special protection for passenger areas. Unlike gas extinguishing systems, there is no need for pre-warning period and open doors or windows do not jeopardise the effectiveness of the operation.

Their suitability as compensation measures was proved in comprehensive independent tests in which many full scale fire tests were carried out. In vehicles requiring more advanced fire protection it was possible to replace fire doAors, to reduce the amount of fire protection material needed and to simplify the verification procedure (such as calculating resistance in the main fire phase).

The reduced installation dimensions and the small pipework diameter means that costs are also kept to a minimum, even in retrofit projects.

As only very small quantities of the extinguishing agent are used, not much storage space is required and weight is kept to a minimum. The systems are ideal to be integrated into rolling stock and are noted for their low life cycle costs and high levels of reliability.

Gas Extinguishing Systems

For smaller electrical equipment or control cabinets it is possible to use compact gas extinguishing systems. These small installations have very few components and can often be integrated into the control cabinets. Nitrogen is normally used, since unlike chemical agents these work without leaving residues.

In rolling stock where both passenger caArriages and such items as closed control cabinets form part of the fire protection risk, combined solutions using both system types can be installed.
