Extinguishing with water – even more effective with water extinguishing systems
Due to the heat absorption capacity of water, the thermal energy is extracted from the fire material and at the same time the adjacent surfaces are cooled down. A further effect results from the partial evaporation of the water, because the resulting water vapor achieves a local inertization of the fire zone. This has the effect of displacing the required atmospheric oxygen. The smaller the individual droplet diameter, the higher the cooling and sticking effect.
Based on the properties of water and their different extinguishing effects, water extinguishing systems are divided into several groups: Sprinkler systems, water mist extinguishing systems or deluge systems.
Now we also have a selectively acting water extinguishing system – our new sprinkler system with a total value of € 425,000.
The sprinklers, through which the water reaches the source of the fire, are sealed by a glass barrel or fusible link. They are activated by a predefined temperature and response sensitivity.
Sprinkler systems are divided into dry and wet systems. Wet systems are constantly under water pressure and the extinguishing effect is immediate when the sprinkler is opened.
Dry systems are mainly installed in areas where there is a risk of frost. Since the pipe network is not filled with water, as in wet systems, but with air or inert gas pressure, when a sprinkler is triggered, the pressure in the pipe network drops and the water supply pressure opens the alarm valve. Through this valve, the extinguishing water enters the pipeline and finally reaches the source of the fire. Our previous extinguishing system was also such a dry system, but there was a risk here that in the event of a triggering, the resulting damage would be higher than with the current system. This is because now, on the one hand, selective extinguishing is carried out and not everything is directly submerged in water, and on the other hand, thanks to the new water tank, extinguishing can be carried out directly without having to wait for the fire department.
The very time-consuming and cost-intensive conversion has now been completed and we can present the final result.
