WATER MIST GENERATOR FOR SHOCK WAVE ATTENUATION

Water mist generator designed for protecting people from unauthorized explosions in underground structures, oil platforms and methane explosion in coal mines.
The new generator activates at the command received from a blast detection wireless system. The activated generator produces a tailored water mist with droplet sizes in the range of 25-400 micron that are discharged along selected sections of a tunnel. Read More

The time of activation from the moment of blast is 11 ms, the mist discharge speed is 60-80 m/s, the volume of discharged water mist is 90-100 liters per activated station, and the shock overpressures are decreased by a factor between 1.9 and 2.3.
