Update to mobile dust suppression machines

10th January 2019


BossTek has updated its family of self-powered dust suppression equipment with Tier IV Final-compliant generators. The company made the announcement with the debut of the new DustBoss DB-60 Fusion, a suppression system driven by a 25HP electric motor and paired with a genset powered by a heavy-duty 4-cycle indirect injection diesel engine. Designed, engineered and assembled in the USA, the generator features a dual-containment fuel cell, heavy gauge lockable enclosure and oversized brushless alternator for easy starting.  

The company expects to unveil two other Fusion models in early 2019.

The new generator series is designed with sound attenuation for 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 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/3,000 hours, with 5-year/5,000 coverage on the electric motor and a 2-year/2,000 hour warranty on the generator.


What Tier IV means

Tier 4 refers to the latest emission milestone established by the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). 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 used in industrial and power generation applications.  

Tier IV-compliant engines are designed to significantly reduce emissions of particulate matter (PM) and oxides of nitrogen (NOx) to near zero levels. Relative to previous emissions standards, Tier IV-compliant engines reduce emissions by over 95% for most agricultural and construction equipment and just over 86% for much larger applications such as locomotives and marine vessels. The Tier 4 emission standards are roughly similar to emission reduction requirements for engines that power heavy-duty trucks.

How it works

The DB-60 Fusion drives 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 30,000 CFM (849.50 CMM) of air flow. Atomised 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° 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 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 square feet (5,834 square meters) of coverage.
