The Ultrasonic Atomising Nozzle takes the form of a whistle using compressed air which accelerates through a converge section and expands to a diverge section into a resonator chamber.
 This produces a powerful sonic shockwave.
Water or other liquids delivered to this sonic area are shattered into droplets. Droplets produced by sonic atomisation are small and relatively uniform in size, in the order of 10 micron, with a low mass and low forward velocity.
The nozzles have a large liquid port which are not prone to blockage.
In practice, the Ultrasonic Atomising System can be utilised in many different industries to provide effective dust suppression.
Wherever there is mechanical handling of any product the system can be incorporated to supply substantial environmental benefits to the process operator.
Examples include conveyor transfer points, crushing or screening equipment and loading/unloading facilities.
 Applications where these benefits are of most importance are: -
- The Recycling Industry.
- Foundries.
- Quarries and Mines.
- Incinerators.
- The Woodworking Industry.
Several nozzles at specific locations throughout the plant, individually controlled from a separate control panel, can be used to obtain optimum conditions.
The installation of the Ultrasonic Atomising System is simple and operation is easy.
The system requires only a compressed air and water supply and in many cases a single nozzle may be sufficient.
- Humidification.
Particularly in agricultural industries for greenhouses and propagation areas.
- Gas cooling
For example in cooling flue gases from furnaces and cement kilns etc.
- Chemical injection.
- Quenching
- Moisturisation.
The advantages of using Ultrasonic Atomising Systems for dust suppression can therefore be summarised as follows: -
- Reduced health hazards.
- Decrease in atmospheric pollution.
- Improved working conditions.
- Efficient operation with minimum use of water thus not saturating the product or plant and equipment.
