New mobile dust suppression design

Louise Davis
A key player in dust and odour control technology has introduced the newest model in its growing family of self-powered dust suppression equipment, as BossTek announces the debut of the DustBoss DB-30 Fusion.  The new design is a versatile and transportable atomised mist unit, engineered with a workhorse electric motor and 30KW generator. Permanently mounted on a rugged road-worthy trailer, the company’s Fusion lineup is proving to be a popular and effective means of delivering powerful dust suppression technology to sites that lack a convenient power source.   
Unlike its larger siblings, water is supplied to the DB-30 Fusion by a standard 5/8″ (15.8mm) garden hose, so it can be used at any location with a working hose bib.  Equipped with an in-line 75 mesh, 200 micron filter, the unit can also be specified with special filtration to accommodate non-potable water sources.  
With an adjustable throw angle from 0-50 degrees of elevation and a range of approximately 30m (100ft) in calm conditions, the standard configuration includes user-definable 359 degree oscillation, allowing the unit to cover as much as 31,000 square feet (2880 square meters) with a powerful dust-trapping mist. The new design can also be optimised with a variable frequency drive (VFD) to precisely adjust fan speed.  An optional dosing pump is available for precise metering of additives to even further enhance particle control.
The extremely water-efficient design consumes just 2.5 gallons per minute.  That’s compared to competing dust control methods such as manual spraying that can use hundreds of gallons per minute, resulting in over-saturation, run-off concerns and higher water costs.
A touchscreen panel for controlling the DB-30 Fusion is encased in a NEMA 3R cabinet, allowing operators to control oscillation, fan and water. The cabinet is constructed for outdoor use, designed to provide protection against solid foreign objects (such as dirt), air (dust, emissions), water (rain, sleet, snow) and ice formation. 
Maintenance requirements for the new design are minimal, even though the unit carries a three-year/3,000-hour warranty on the dust suppressor and a two-year/2,000-hour warranty on the gen set. If potable water is being used, nozzles typically need to be inspected just once per year. The turntable bearing on the oscillator should be greased annually or as needed for harsh service conditions and the fan motor should be lubricated every 10,000 hours. Like any diesel engine, the gen set should have regular inspections and changing of oil, coolant and filters.
