Description and Applications

The principle of operation of the shutdown flood water is to a simultaneous application of all the protected area with the main objective to cool the structures and equipment affected by the fire in the vicinity or maintain a state of control over ‘fire, while waiting for the Fire Brigade

Plant flood tank The plant shutdown deluge requires for its operation a control group, through which the water, in quantity due to pressure, enters the pipe network to be delivered. The control group operates as a group on-off and can therefore only be fully opened or closed.

The activation system is effected by means of a system of fire detection of the electronic type or hydraulic means of sprinkler heads closed, pressurized water or air.

When a single head is opened, the pressure escapes from the network and the deluge valve opens.

It ‘important to remember that the supply lines of the deluge systems, been subject to periodic wetting and drying may be subject to severe corrosion by rust, it is therefore advisable to use in the installation of piping hot galvanized, internally and externally.

The extinguishing systems in flood water cooling systems are to be used outdoors, on installations, on fuel tanks and large transformers.

The surface water to create heat shields are now widely used to protect areas adjacent to oil facilities, railway stations to prevent the smoke and hot gases from burning locomotives to flood escape routes and partitioning of underpasses road and railway tunnels. Are, however, subject to the presence of air currents. For the construction of water barriers are mainly used in medium speed nozzles that produce a round jet of water is particularly divided, suitable to achieve a high heat absorption.
