Dust suppression systems

Salma & Duztech are world leaders in the use of water for dust suppression. They have decades of experience in the manufacture of standard equipment and offering customized projects and complex solutions through studies for fixed or mobile installations of water cannons and spray systems.

Operating principle

Fog and mist cannons produce particles of water in suspension. These particles moisten the material and unleash the agglomeration of the dust particles to sizes large enough to settle. Once the powder drops reach the soil, the water evaporates leaving the material dry.



  • Dust suppression with water
  • Dust control with water
  • Spraying a mixture of water and chemical additives to improve dust suppression
  • Dry fog (combination of air + water)
  • Refrigeration of spaces with high temperature (indoor and outdoor)
  • Sealing of coal stockpiles
  • Odour suppression
  • Evaporation of water in pools (EVAP)
  • Wetting of roads and areas with traffic of trucks and heavy vehicles
