Fine sprayed water extinguishing is a modern and highly efficient fire extinguishing technology. As a fire extinguishing agent, water is used, supplied under high pressure through special spray nozzles, which create a fine mist of droplets no more than 100-150 microns in size, which quickly fills the protected area. In this case, a high efficiency of extinguishing fires is achieved with a minimum volume of consumed water. Water mist fire extinguishing modules are absolutely environmentally friendly and completely safe for humans. This allows the use of this technology in residential premises, trade pavilions, industrial workshops and other premises with the presence of people.
