HPW-DUST High Pressure Dust Suppression System

DYNASET HPW-DUST High Pressure Dust Suppression System is the most innovative dust control system for mobile machinery in demolition, street cleaning, quarrying, crushing, recycling etc. The system produces targeted atomized water mist to suppress the dust and prevents the emissions from spreading to the environment. 

The HPW-DUST High-Pressure Dust Suppression System creates an atomized water mist that effectively suppresses dust and prevents harmful emissions from spreading into the environment at the source. As the most advanced dust control system for mobile machinery, it is ideally suited for applications such as demolition, street cleaning, quarrying, crushing, recycling, mining, tunneling, and material handling. By controlling dust emissions at their origin, you eliminate the need for dust cannons to wet your worksite! Engineered for efficiency and minimal water consumption, the system enhances air quality and working conditions while reducing time and labor demands. Thanks to its low water consumption, it prevents your worksite from becoming a muddy field. Installation-ready kits are available for seamless integration into existing hydraulic systems.

Applications

Prevent and control dust emissions in street cleaning, demolition, recycling, quarrying, mining, crushing, material handling, tunnelling and drillling.

Key Benefits and Features 

  • Produces a targeted water mist with extremely small droplet size directly at the dust source for effective suppression. 
  • Dust suppression is activated directly from the machine cabin when needed 
  • Reduces PM10 dust concentrations during street brushing by 82% compared to no dust control and by 52% compared to low-pressure systems (based on impartial research by Metropolia University of Applied Sciences). 
  • Keeps air cleaner after brushing and reduces health hazards at street level and worksites (according to impartial research by Metropolia University of Applied Sciences). 
  • Prevents muddying and does not wet the worksite or street, enabling brushing and demolition without excess water. 
  • Compact and lightweight kits for crushers, excavators, and sweepers that are easy to install on all hydraulic systems. 
  • Modular structure makes it possible to add dust suppression to any machine. 
  • Saves time, space, labor costs, and water compared to traditional dust cannons or manual dust suppression methods 
  • Improves working conditions, such as visibility, especially during tunneling jobs. 
  • Equipped with a robust, self-priming HPW High-Pressure Water Pump. 
  • Linear output adjustability from 0% to 100% by controlling hydraulic flow. 
  • Dust suppression nozzles can be mounted on machine attachments for targeted application. 
  • Includes a power washing gun for pressure washing. 
  • Optional Double Dust Boosting System for enhanced dust control. 
  • Industry-leading power-to-size and power-to-weight ratios for pumps.

How Does the High Pressure Dust Suppression System Work?

The hydraulic high-pressure dust suppression system uses the hydraulic system of a machine, vehicle, or vessel as its power source to generate high-pressure water mist for efficient dust suppression. 

  1. Hydraulic oil flow is directed to the hydraulic high-pressure water pump via the pressure line. 
  2. The pump converts the hydraulic oil flow and pressure into high-pressure water. 
  3. The hydraulic oil is then returned to the carrier machine’s hydraulic oil tank through the return line. 
  4. Water is drawn from the source and delivered to high-pressure nozzles at the correct pressure level, creating an atomized water mist. 
  5. The atomized water mist, composed of tiny water droplets, effectively suppresses dust.
