Low-pressure water mist systems are the suitable solution if you are looking for a reliable extinguishing system with low water consumption that is also space-saving and budget-friendly. It is the perfect happy medium between a high-pressure water mist system and a sprinkler system. Water consumption with a low-pressure water mist system is no less than 20% lower than with a sprinkler system.
The system
How does a low pressure watermistsystem work
The low-pressure water mist system works approximately on the same principle as a high-pressure water mist system, but enjoys the price advantage of a sprinkler. The low-pressure water mist system has nozzles that operate under a pressure of 2 to 12 bar. This pressure creates water droplets of different sizes. The large water droplets penetrate to the core of the fire, while the smaller water droplets cool the fire and displace the oxygen until the fire is extinguished.
