Doosan excavator with dust suppression system

Preston-based demolition and groundworks specialist I&R Demolition Limited recently equipped its new Doosan DX255 excavator with an on-board dust suppression system which was supplied and installed by hydraulic attachment specialist ECY Haulmark.

I&R Demolition Director Ryan Tomlinson spoke of their recent decision to utilise an on-board system over more traditional dust suppression systems. After researching various methods for on-site dust suppression, Ryan explained the on-board set up offered significant benefits and cost savings compared to other traditional dust suppression systems, such as expensive mobile/trailer based units or hosepipes which trail inconveniently across site and are subject to regular damage.

He explained their new on-board system sees a self-contained tank mounted on a frame with a pump system all installed to fit neatly behind the cab of the machine. The tank on the Doosan DX255 can hold 350 litres of water and typically requires refilling every 3 to 4 days when the machine is active all day. A fine mist can be atomised on demand from the touch of a button in the cab, so water is only being used when required at the exact point of demolition activity. Also the on board system eliminates any need for hoses running across the site to a mains water supply.

The set up incorporates a Dynaset HPW pump installation which converts the hydraulic power of the mobile machine into a high pressure water mist. It is integrated onto the base machine with water hoses connected and installed up to the attachment head or where the dust suppression is needed to get the maximum effect. The system creates an effective high pressure dust control with optimal water consumption. High pressure water uses less water and gives better dust suppression performances with a smaller water drop size than traditional low pressure dust suppression systems.

The Dynaset HPW-DUST patented piston-to-piston pump converts the hydraulic power into high pressure water, which is pumped to the dust suppression nozzles which create the atomised water mist. The compact HPW-DUST is said to be easy to install onto any mobile machine. It is suitable for demolition machinery, excavators, screeners and crushers. The nozzles of the HPW-DUST are installed either straight to the attachment head or anywhere dust suppression is needed. The complete Dynaset HPW-Dust on-board dust suppression system is available for sale and installation in the UK from ECY Haulmark Ltd.
