BossTek updates dust suppression equipment

BossTek, a global innovator in dust and odour control technology has updated it family of self-powered dust suppression equipment. The equipment now features tier IV final-compliant generators, ensuring compliance in all 50 states.

The announcement was made with the debut of the company’s new DustBoss® DB-60 Fusion. This is a field-proved suppression system that is driven by a high-reliability 25 hp electric motor and paired with a generator set. It is powered by a heavy-duty four-cycle indirect injection diesel engine. The generator features a dual-containment fuel cell, a heavy guage lockable enclosure, and an oversized brushless alternator for easy starting. It is designed, engineered, and assembled in the US.

Proving to be a popular and effective means delivering versatile, mobile dust suppression technology to plants that lack a readily available power source, the company’s Fusion lineup is permanently mounted on a rugged road-worthy trailer. The company is expecting to unveil two other Fusion models in early 2019. These will give 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 noise reduction, and a multi-voltage switch with a utility power outlet in all voltage models. Equipped with single-button stop/start and an 80 gallon fuel capacity, the digital engine/gallery controller gives the units a run time of more than 24 hours, at a prime rating of 45 kVa. As with its previous Fusion systems, the company provides a three year (or 3000 hour) warranty for the DB-60 Fusion. There is also five year (or 5000 hour) coverage on the electric motor, and 2 year (2000 hour) warranty on the generator.

What Tier IV means

Tier IV is the latest emission milestone to be established by the US Environmental Protection Agency and the California Air Resources Board. The regulations apply to new engines found in off-road equipment, including construction, mining, and agricultural equipment, as well as marine vessels, locomotives, and stationary engines that are used in industrial and power generation applications.

Tier IV-compliant engines are designed with the aim of significantly reducing the emissions of particulate matter and nitrogen oxide to near-zero levels. These engines reduce emissions by over 95% for most agricultural and construction equipment and 86% for larger applications (such as locomotives and marine vessels). This is compared to previous emissions standards. The Tier IV emission standards are roughly similar to emission reduction requirements for engines that power heavy-duty trucks.

How it works

With 30 atomising spray nozzles, the DB-60 Fusion drives pressurised water through a circular stainless steel manifold. It then launches millions of tiny droplets with a powerful fan, which produces 30 000 CFM (849.5 CMM) of air flow. Atomised mist droplets, which are between 50 and 200 microns in size, are thrown 200 ft (60 m) into a cone at an adjustable 0° to 50° elevation angle. This captures airborne dust particles and drags them to the ground. Where industrial sprinklers that are used for the same purpose require hundreds of gallons of water per minute, the DB-60 only uses about 23 gallons/min. This helps to avoid pooling or runoff.

For controlling the dust suppression unit, a touch screen panel is encased in a NEMA 3R cabinet. This allows operators to control the oscillation, booster pump, fan, and water. Constructed for outdoor use, the cabinet is designed to provide protection against solid foreign objects (such as dirt), air (dust, emissions), water (rain, sleet, snow), and ice formation. In one of the most popular and effective dust suppression designs on the market, the system provides valuable mobility and versatility. This enables it to deliver up to 62 800 ft2 (5834 m2) of coverage.

The unit can be specified with special filtration to accommodate non-potable water sources, and is equipped with an in-line 75 mesh, 200 micron filter. The design can also be optimised with a variable frequency drive, in order to precisely adjust fan speed. An optional dosing pump is available for the precise metering of additives to enhance particle control even further.

“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,” said Jason Lesch, Project Engineer. “We engineered the Fusion to be highly mobile, with its own power source, so it can be easily towed anywhere on a job site.”
