BossTek made the announcement with the debut of the new DustBoss DB-60 Fusion, a field-proven suppression system driven by a high-reliability 25hp (18.6kW) electric motor and paired with a genset powered by a heavy-duty four-cycle indirect injection diesel engine. Designed, engineered and assembled in the US, the generator features a dual-containment fuel cell, heavy gauge lockable enclosure and oversized brushless alternator for easy starting.
Permanently mounted on a rugged road-worthy trailer, the company's Fusion lineup is an effective means of delivering versatile, mobile dust suppression technology to sites that lack a readily available power source. The company expects to unveil two other Fusion models in early 2019, giving customers the ability to select the size and coverage range needed to best suit their operations.
The new generator series is designed with sound attenuation for excellent noise reduction and a multi-voltage switch with utility power outlet in all voltage modes. The digital engine / generator controller is equipped with single button stop / start and an 80-gallon (302.8L) fuel capacity, giving the units a run time of more than 24 hours at a prime rating of 45kVa. Like its previous Fusion systems, BossTek warrantees the DB-60 Fusion for three years or 3,000 hours, with five-year / 5,000 hour coverage on the electric motor and a two-year / 2,000 hour warranty on the generator.
The DB-60 Fusion works by driving pressurised water through a circular stainless-steel manifold with 30 atomising spray nozzles, then launches millions of tiny droplets with a powerful fan that produces 849.50 cubic metres per minute (CMM) of air flow. Atomised mist droplets of 50-200 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 hundreds of gallons of water per minute, the DB-60 only uses about 87 litres per minute (LPM) to help avoid pooling or runoff.
A touchscreen panel for controlling the dust suppression unit is encased in a NEMA 3R cabinet, allowing operators to control oscillation, booster pump, 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. The system provides valuable mobility and versatility in one of the most popular and effective dust suppression designs on the market, able to deliver up to 5,834m2 of coverage.
Jason Lesch, project engineer at BossTek, said: "Maintaining air quality is essential for communities near a demolition project, mining operation or other bulk material handling activities, but even in places with little infrastructure, dust can choke worksites and foul equipment. We engineered the Fusion to be highly mobile, with its own power source, so it can be easily towed anywhere on a job site."
Equipped with an in-line 75 mesh, 200 micron filter, the unit can be specified with special filtration to accommodate non-potable water sources. In addition, the new design can 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 enhance particle control even further.
