Sprinkler fire extinguishing system: efficiency and reliability in fire fighting

Sprinkler fire extinguishing system is one of the most common and effective ways to fight fires. Its main function is automatic detection of ignition and immediate local extinguishing of fire using water. This system is most often used in offices, shopping malls, residential buildings, warehouses and other facilities with a moderate level of fire hazard.

How do sprinkler systems work?

A sprinkler system consists of pipelines, sprinklers (nozzles), pumping equipment and water tanks. It is activated automatically, responding to an increase in temperature, which makes it one of the most convenient and reliable solutions for ensuring fire safety. 

The principle of operation of a sprinkler system is based on the sensitivity of nozzles to temperature. Each sprinkler is equipped with a thermal lock (glass bulb or fusible element), which is triggered when a certain temperature level is reached (usually from 57 to 77 °C).

When the temperature rises to a critical level:

• the glass bulb breaks or the fusible element collapses;

• the nozzle opens, through which water begins to flow;

• the water is evenly distributed sprays, covering the area of ​​ignition.

The sprinkler system works locally: only those nozzles that are in the area of ​​elevated temperature are activated. This reduces water consumption and minimizes damage to the premises.

Despite their similar function of extinguishing a fire, sprinkler and drencher systems have significant differences. In a sprinkler system, the nozzles are closed by a thermal lock and are triggered only when a high temperature is reached. In a drencher system, the nozzles are always open, and the supply of water or other substance is activated for the entire system simultaneously.

A sprinkler system works locally, extinguishing only the center of the fire. A drencher system provides coverage of the entire area of ​​the room.

Sprinkler installations are used in facilities with a moderate risk of fire, such as offices, shopping centers and warehouses. Drencher systems are suitable for industrial facilities with high fire risk, such as chemical plants or oil storage facilities.

Automatic sprinkler fire extinguishing systems: main advantages

Sprinkler systems have a number of significant advantages that make them an ideal choice for many facilities:

• Automaticity. The system operates independently, which reduces dependence on the human factor and shortens the response time to a fire;

• Economical. Due to local action, only the necessary nozzles are activated, which saves water and reduces damage associated with flooding;

• Quick response. Sprinklers begin to operate immediately upon reaching a critical temperature, which allows you to localize the fire at an early stage;

• Reliability. The system design is simple and has been tested for years, which guarantees its trouble-free operation subject to regular maintenance;

• Versatility. Suitable for various types of objects - from residential buildings to large warehouses and industrial premises.
