Dust Control Technology launch new Midget nozzles

Latest nozzle design developed specifically for applications requiring smaller droplet sizes to minimize surface wetting

DUST-suppression specialists Dust Control Technology have introduced a new nozzle design for their atomized misting equipment, developed specifically for applications requiring smaller droplet sizes or reduced water volumes for minimizing surface wetting.

Responding to customer requests, the new Midget nozzles are well suited to indoor applications, such as recycling and transfer stations, in which reduced water volumes are desired. Key benefits include improved worker safety and comfort, reduced moisture in end-products and better odour control.

‘Some dust management applications are particularly sensitive to excess water,’ explained Carl Harr, technical sales specialist for Dust Control Technology. The Midget nozzles gives users an option that delivers very good particle control, while reducing the total water applied by around 65%.’

For example, Dust Control Technology’s smaller fan-driven atomizer, the DustBoss DB-30, has a flow rate of around 2.2 gal/min at 4.1 bar (60 psi) with a standard nozzle configuration. However, when equipped with the new Midget nozzles, the flow rate is cut to just 3 quarts per minute.

‘The nozzles also deliver a consistently smaller droplet size, which can be an advantage with very fine particulates,’ continued Mr Harr. ‘While the overall size range is still 50–200 microns, the water is atomized to a consistently smaller droplet, producing greater numbers in the lower size range.

‘The small size nozzle also means that the dust-trapping droplets are lighter in weight, so they tend to hand in the air longer, giving them longer exposure time to airborne particles.’
