Dust Control Technology (DCT), Peoria, Ill., has announced that its DustBoss product line now includes a low-turbulence design for applications where a fan-driven mist is undesirable.
The company’s DB-M has been designed to operate in conditions involving very fine dust particles, including slag dust or fly ash. The unit generates an umbrella-shaped cloud of atomized droplets that average between 50 and 200 microns. The DB-M can project the mist about 30 feet under calm conditions, the company says.
The DB-M’s misting head is supplied standard with nine atomizing nozzles and mounted on a 15-foot boom. DCT says the product can be customized for specific dust types, particle behaviors or operating environments.
 “There are a number of applications where a fan-driven dust suppressor would introduce too much air movement,” Edwin Peterson, DCT CEO, says. “In some cases, that could actually cause ground-level dust to become airborne.” 
The design features selectable flow settings and the company’s variable particle sizing (VPS) technology to improve capture efficiency. Nozzles can be added, removed or resized as applications dictate.
The DB-M requires 10 PSI (pounds per square inch) of water pressure from the supply hose when using the integrated booster pump, giving the DB-M an output as high as 24 GPM at 200 PSI. An in-line 30-mesh filter stops any solids 600 microns and larger, and the manufacturer recommends that it be used at all times. If using potable water, nozzles can be inspected just once a year. 
The full current load is about 12 amps and can be configured to match power supplies in virtually any region in the world, according to DCT.
The DB-M can be supplied with an optional dosing pump for precise metering of odor control additives, surfactants to improve binding to dust particles or tackifying agents to help seal ground-level dust and prevent it from becoming airborne.
