The extinguishing system will be automatically activated by a pneumatic trigger in the event of a critical

rise in temperature (e.g. 30° above the maximum expected operating temperature). This may also done

remotely by electronics or pneumatics. Our fire-fighting system is a fine-spray extinguishing system

which uses special nozzles to spray the extinguishing agent as a fine mist. The droplet size selected is

large enough to ensure that the droplets have enough kinetic energy to reach the source of the fire.

This is particularly important in wind turbines as there may be air flows in the nacelle which prevent this.

The enormous reaction surface of the mist droplets in relation to the quantity of The enormous reaction surface of the mist droplets in relation to the quantity of extinguishing agent

means that the fire is quickly deprived of a great deal of its energy and the temperature level therefore

falls rapidly, thus preventing re-ignition. The cooling effect disrupts the thermal reaction conditions in

the seat of the fire, thereby reducing the reaction speed.

To intensify the extinguishing effects described, the extinguishing agent contains a foam-forming additive.

The purpose of this is to achieve greater adhesion, thereby improving the success with which the

burning materials are extinguished. This mixture plays a crucial role in the effectiveness of the system

for specific risks in areas where there are combustible liquids .for specific risks in areas where there are combustible liquids .

In the interpretation of the extinguishing

concept, the focus is not on protecting the

nacelle as an area protection but instead

protecting individual objects.

As a minimum, the following neuralgic

points are to be protected in wind turbines:

This allows any fires breaking out to be systematically and quickly detected, enabling the spread of the fire

to be extinguished before it really takes hold.
