New mist unit to eliminate dust
US-based Dust Control Technology (DCT) has developed a transportable atomised mist unit which combines a workhorse electric dust suppression design with a 45 KW generator set to capture dust emissions.
The DustBoss DB-60 Fusion is a powerful suppression system with an efficient diesel generator which can be hauled to job sites that lack a convenient power source. DCT says the new development brings even greater versatility to one of the most popular and effective dust suppression designs on the market, able to deliver up to 5,834m² of coverage.
“Controlling air quality is essential for communities surrounding a construction or demolition project, but even in places with little infrastructure, dust can choke worksites and foul equipment,” said Laura Stiverson, president, DCT. “We engineered the Fusion to be highly mobile, with its own power source, able to be easily towed anywhere on a job site.”
The DB-60 Fusion forces water through a circular stainless steel manifold with 30 atomising spray nozzles, then launches millions of droplets with a powerful 25 HP fan that produces 30,000 CFM (849.50 CMM) of air flow. Atomised mist droplets of 50 to 200 microns in size are thrown out in a 60m cone at an adjustable 0 to 50° elevation angle, capturing airborne dust particles and dragging them to the ground. Unlike industrial sprinklers used for the same purpose, which can require 500 GPM (1893 LPM) or more of water, the DB-60 uses about 23 GPM (87 LPM) to help avoid pooling or runoff.
The unit is paired with a 45 KW gen set featuring a John Deere Tier III Flex engine featuring a 100-gallon fuel tank, allowing up to 24 hours of runtime. The efficient diesel engine delivers 480 Volts (60 Hz) with a full load current of 46 amps. The Fusion also has a 120-volt outlet to provide jobsite power for any accessories or tools.
“We’ve seen competing designs on the market that have a diesel engine powering the dust suppressor, using a drive belt system similar to a vehicle,” added Ms Stiverson. “In comparison, the direct drive electric motor used in the Fusion dramatically reduces maintenance requirements, delivering superior reliability and long service life.”
The DB-60 and gen set are mounted together on a heavy-duty trailer with a steel frame and roadworthy tires for towing at highway speeds. Weighing a total of 2,971 kilos, it can be towed with virtually any vehicle with suitable towing capacity equipped with a Class IV ball hitch.
At just 80 inches (2.03 meters) wide, it can be placed virtually anywhere dust suppression is needed and adjusted based on changes in wind or work activity.
A touch screen panel for controlling the dust suppression unit is encased in a NEMA 3R cabinet allows operators to control oscillation, booster pump, fan and water. The cabinet is built for outdoor use, designed to provide protection against ingress of solid foreign objects (such as dirt), air (dust, emissions), water (rain, sleet, snow) and ice formation.
In addition to the control panel for the DustBoss, the unit features an on/off function for the gen set located outside the generator itself. Full control and maintenance readings are located on a control panel inside, but operators do not need to access the interior to turn it on and off.
