Mobile Dust Suppression Design Features Tier IV Final Gen Set
BossTek has updated its family of self-powered dust suppression equipment with Tier IV Final-compliant generators with the debut of the new DustBoss® DB-60 FusionTM, a field-proven suppression system driven by a high-reliability 25-hp (18.7-kW) electric motor and paired with a gen set powered by a heavy-duty 4-cycle indirect injection diesel engine. The generator features a dual-containment fuel cell, heavy gauge lockable enclosure and oversized brushless alternator for easy starting.
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-litre) fuel capacity, giving the units a run time of more than 24 hours at a prime rating of 45 kVa. BossTek warrantees the DB-60 Fusion for three years/3,000 hours, with five-year/5,000 coverage on the electric motor and a two-year/2,000 hour warranty on the generator.
The DB-60 Fusion drives pressurized water through a circular stainless steel manifold with 30 atomizing spray nozzles, then launches millions of tiny droplets with a powerful fan that produces 30,000 ft3/min (849.50 m3/min) of air flow. Atomized mist droplets of 50 to 200 microns in size are thrown out in a 200-ft (60-m) cone at an adjustable 0 to 50-degree 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 23 gallons/min (87 litres/min) to help avoid pooling or runoff.
A touch screen 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 62,800 ft2 (5,834 m3) of coverage.
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 optimized 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.
BossTek 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.
