BossTek debuts new DustBoss DB-60 Fusion dust-suppression system

BossTek, Peoria, Illinois, has announced the release of the new DustBoss DB-60 Fusion. The DustBoss DB-60 Fusion is a field-proven suppression system driven by a 25-horsepower electric motor that’s paired with a gen set featuring a heavy-duty four-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 generators are Tier IV Final-compliant. Tier IV refers to the latest emission milestone established by the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). Tier IV-compliant engines are designed to significantly reduce emissions of particulate matter (PM) and oxides of nitrogen (NOx) to near zero levels. 

Permanently mounted on a rugged trailer, the company’s Fusion lineup is proving to be a popular and effective means of delivering versatile, mobile dust-suppression technology to sites that lack a readily available power source, the company says. The company says it 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 stop/start button and an 80-gallon fuel capacity, giving the units a run time of more than 24 hours at a prime rating of 45 kVa. Like its previous Fusion systems, BossTek warrantees the DB-60 Fusion for three years or 3,000 hours, with five-year or 5,000-hours coverage on the electric motor and a two-year or 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 CFM (849.50 CMM) of airflow. Atomized mist droplets of 50 to 200 microns in size are thrown out in a 200-foot (60-meter) 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 GPM (87 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, water 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 square feet (5,834 square meters) of coverage, the company says.

“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,” Project Engineer Jason Lesch says. “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 nonpotable 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.
