Sprinkler
The SPRINKLER fire protection system has been developed for the purpose of protecting fire objects from the fire extinguishing system by sprinkled water from the pipe. These tubes are guided directly below the ceiling or inside the lowered ceiling. The Sprinkler uses water, and by activating it simultaneously with the extinguishers, it also performs an automatic fire alarm. The main elements of sprinkler systems are sprinkler nozzles that respond to rising temperatures in the protected area.
Sprinkler systems are commonly used in:
Shopping malls – Hotels – Public underground and overground garages – Industrial plants
Sprinkler devices are the most common firefighting installation in the world, and are used to protect various types of objects from:
– small fire loads: hotel complexes, libraries, hospitals, skyscrapers, kindergartens, school facilities etc..
– medium fire loads: public garages, shopping centers, restaurants, process and food industry, wood industry, textile industry, etc.
– large fire loads: all types of warehouses, chemical industry, paint and varnish factories, textile industry warehouses, paint shops, hangars etc.
The advantages of sprinkler devices compared to other protective systems are in maintenance, high efficiency of extinguishing and no false alarms. In the case of fire activation, only those nozzles that are located in the part of the area affected by the fire are working, so that there is minimal damage to the action of the water in the protected area.
At the same time, the valve activates the hydraulic alarm bell that gives an intensive alarm, and via the fire alarm control unit informs the person in charge.
The principle of sprinkler system operation:
– the nozzle activation temperature is higher for 30˚C than the highest operating ambient temperature.
– when a fire occurs, temperature rise is suddenly triggered by the nozzle activation and it is possible to pass water through the pipeline at a pressure of max. 10 bar
– fire detection at the sprinkler system is based on a sudden drop in pressure in the pipeline, due to the sprinkler nozzle activation
– sprinkler systems divide on wet and dry systems depending on the type of space and the minimum temperature in it
The wet sprinkler system is used in facilities where there is no risk of freezing or evaporating water.
A dry sprinkler system instead of water uses compressed air and is applied in low-temperature facilities.
All sprinkler systems are very easy to maintain, efficient in fire extinguishing and fire detection and are more reliable.
Only those spray nozzles that are in the flammable area are activated in the fire, thus preventing water damage in the other part of the screen area. The amount of fire extinguishing water is minimal and thus damages are minimized. After activation, the system quickly returns to re-function without large and unnecessary costs.
When firing in objects that are shielded by sprinkler systems, damage to property is minimal, and no injured or killed.
