BossTek releases new dust control cannon

Environmental, Mining equipment, Mining services, Water management,

In response to input from customers across the demolition and bulk material handling sectors, BossTek, a leader in atomised mist technology, has introduced a powerful new mobile mid-sized dust control cannon.

The DustBoss® DB-45 Surge® is the next iteration of the popular Surge series featuring an innovative pressurised centre nozzle paired with the industry-proven fan and misting ring system to suppress both surface dust and airborne particulates, the company says. With three remote–controlled stages and precision oscillation for optimum command over water volume and coverage area, the DB-45 Surge delivers the dependability of atomised mist along with J2P (jet-to-plume) nozzle technology that surges for over 60 m, even in troublesome windy conditions, the company claims. The result is an easily manoeuvrable, autonomous and versatile dust control solution for outdoor operations in all weather conditions.

“Our first iteration of this technology was larger for operations with high-reach cranes and enormous coverage areas,” BossTek Dust Control Specialist, Mike Lewis, said. “Managers of medium and smaller operations were impressed with the existing technology but wanted a lighter and more compact option that offered the same excellent field-tested versatility and results. With a 200-ft (60 m) throw range, I’d say that most of our customers will be well-served by the new model.”

Bulk handlers with tall stockpiles of raw material commonly experience windy conditions high above the ground. In turbulent situations, dust is lifted into the atmosphere and carried beyond the site line over long distances, which can lead to permit violations. Operators often mitigate particulate emissions using sprinklers or hoses to saturate a material’s surface. The stronger the wind, the more water pressure is required to break through the wind shear, resulting in greater amounts of water filling the surrounding work area – often 300 GPM (1,135 lpm) or more.

The DB-45 Surge combines the power of a 25-horsepower industrial fan, misting ring and heavy-duty barrel with the reach of a central high-pressure spray nozzle. The misting ring introduces millions of tiny dust capturing droplets into an area for proven dust suppression. The pressurised spray resists wind shear and uses the force of the wind to further fragment droplets, enhancing its dust suppression capabilities. This is achieved with a maximum of 72 GPM (372 lpm) and as little as 17 GPM (77 lpm) when using only the misting ring and fan. The cannon also features a VFD (variable frequency drive),which allows the unit to operate more efficiently at lower water pressure.

The three stages are input by the touch screen system, protected by a sealed NEMA 4 cabinet or controlled by a heavy-duty hand-held remote control with a 1,000 ft (305 m) range. Stage one is highly effective on moderate days and uses the powerful 30,000 CFM (849.5 CMM) fan and misting ring for wide area coverage. For windy days, stage two features a pressurised stream delivered by the J2P nozzle to pinpoint the source of the dust. On high wind days, operators can choose stage three which uses the fan, misting ring and centre nozzle for maximum coverage.

This allows the DB-45 Surge to be “set it and forget it” autonomous equipment, unlike hoses and industrial sprinklers, which typically require constant manual labor to monitor and operate, BossTek claims. Manual operation keeps workers in active zones near moving equipment, increasing the chance of injury and raising the costs of operation for sprinklers and hoses due to extra labor and possible liability.

The DB-45 Surge addresses wind, labour and water usage issues. While striving to stay compliant with dust regulations, operators can now better match the water requirements to the specific application. Fed by a standard 38 mm hose with a cam-and-groove quick disconnect coupling, the powerful booster pump delivers as much as 500 PSI (27.5 bar) of water pressure to the centre nozzle.  

The coverage area is extended with the customisable 260º horizontal oscillation range and 0º-50º vertical throw angle. Mounted on a heavy-duty roadworthy trailer for towing at highway speeds with a standard ball hitch, it can be placed by a pickup truck, skid steer or lift truck wherever dust suppression is needed. As supplied, the DB-45 Surge can run potable or non-potable water, as it is equipped with two in-line 30 mesh, 595 micron filters to avoid clogging. One filter is located at the water entry point to the booster pump and another is located prior to the pipe feeding the central nozzle.

Other options are already available, including tower mounting for permanent locations. The cannon is also available as part of the company’s popular “Fusion” lineup, pairing the DB-45 Surge with a trailer-mounted generator to alleviate the need for a nearby power source. With a 15 hp booster pump, the unit only requires a 45 kW generator, which most demo contractors already have in their equipment arsenal.

“The DustBoss product line is known for its rugged quality and long service life, often described as one of the most reliable and low–maintenance pieces of equipment on any job site,” Lewis concluded. “Our 3-year or 3,000-hour warranty is evidence of our confidence in the products.  The DB-45 Surge is designed with that same philosophy: it’s built to last.”

BossTek ups the dust suppression ante with new compact DustBoss DB-10 unit

BossTek has introduced a new model to its atomised mist cannon range that suppresses indoor particulate emissions for industries such as raw material handling

The compact DustBoss® DB-10 is engineered for enclosed working environments, with the manoeuvrable unit providing excellent suppression in a compact, portable design, the company says. The outcome is effective airborne particle control with fewer emissions, less standing water and a safer, more compliant workplace.

“Our customers are well-acquainted with our technology, but before the DB-10, the smallest machine could nearly cover a football field, which is far too powerful for most indoor applications,” Mike Lewis, Dust Control Specialist at BossTek, says. “Our first customer to use the DB-10 was a demolition contractor removing dusty drywall, plaster and tile containing potentially hazardous materials. These all produce highly regulated dust emissions. We worked with them to create a unit best suited to their needs and the DB-10 was born. They are extremely happy with the outcome.”

The compact mist cannon is mounted on two wheels with a tall handle. A 0.75 horsepower (0.56 kW) fan delivers 3,335 cubic feet per minute (5,666 cu.m/h) of airflow, powered by 120 V current. Mounted on the front of the cannon is a circular manifold with 12 atomising nozzles that fracture pressurised water into a fine mist. The fan forces air through the barrel then pushes millions of tiny droplets in a cone-shaped pattern up to 10 m. Using the 0-50º vertical adjustment, the mist can reach into far expanses or be directed at specific emission zones. It is offered with a standard wheeled carriage but can be specified with alternate mounting as needed.

One driver of the new design is the fact that hoses create droplets up to 100 times larger than atomised mist, far too large to capture airborne particulates. They can use up to 100 gallons per minute (379 litres per minute) of water, causing excessive standing water and runoff, a potential hazard. The DB-10 addresses all these issues.

The DB-10 produces droplet sizes of 50-95 microns in size, roughly the same as the cross-section of a single human hair. This is important because regulators test for respirable dust 10 microns or less. The slipstream created by droplets greater than 200 microns in size can deflect tiny respirable dust particles, rather than absorbing them. That’s why hoses are generally not effective against airborne dust.

Using less than a quarter of the water volume of a handheld 25.4 mm hose, the DB-10 fills the area with a dust-trapping mist that stops particulates from remaining airborne or migrating away from the area, according to the company. The wide area of distribution and gentle settling reduces the chance of pooling and runoff.

BossTek brings in DustBoss DB-60 Surge reinforcement to fight dust

BossTek says it has introduced an advancement in industrial dust suppression with a powerful cannon that is designed to fight dust with maximum efficiency.

Developed in response to the needs of customers in areas with variable winds, the DustBoss® DB-60 Surge® features water propelled at high velocity from a center nozzle, combined with an industry-proven fan and misting ring system.

With three remote-controlled stages and precision oscillation for optimum command over water volume and coverage area, the cannon uses high-powered jets that surge through the wind for over 250 ft (76.2 m) to suppress both surface and airborne dust. The result is effective and versatile dust mitigation in challenging weather for outdoor operations ranging from demolition to bulk material processing and storage, it says.

BossTek Dust Control Specialist, Mike Lewis, says: “Our customers operate in very different circumstances; some with high-reach excavators, some in open areas without natural barriers, while others are located in narrow corridors where wind velocity is amplified. What these customers have in common is the difficulty in controlling fine atomised mist during blustery conditions. So we worked with our industry partners, listened to their feedback and engineered our most versatile and innovative machine to date.”

The DB-60 Surge combines the power of an industrial fan, misting ring and heavy-duty barrel with the reach and force of a central high-pressure spray nozzle, BossTek explains. The pressurised spray resists wind shear and even uses the force of the wind to further fragment and carry the droplets, enhancing its dust suppression capabilities. This is achieved without the need for the high water output associated with a hydrant-dependent hose or industrial sprinkler system, the company claims.

In high-wind situations, dust is lifted into the atmosphere and carried beyond the site line over long distances, which can lead to permit violations. Operators of bulk storage mounds (such as mining companies), demolition sites, ports, recycling material piles, etc often mitigate particulate emissions using a sprinkler or hose to saturate a material’s surface. The higher the wind, the more water pressure is required to break through the shear, resulting in greater amounts of water filling the surrounding work area – often 300 gallons per minute (1,135 litres per minute) or more.

There are several issues associated with the use of hoses and industrial sprinklers. Hoses typically require manual labour, removing workers from other critical tasks. Moreover, both sprinklers and hand-held hoses contribute to high water bills. Taking compliance and expenses into consideration, the long-term cost of operation for sprinklers and hoses is higher than it might appear.

The DB-60 Surge addresses wind, labor and water usage issues. While striving to stay compliant with dust regulations, operators can now better match the water requirements to the specific application. Fed by a standard 1.5 in (38 mm) hose with a cam-and-groove quick disconnect coupling, the powerful booster pump delivers as much as 500 psi (27.5 bar) of water pressure to the centre nozzle, with an output of 37-100 g/min (140-378 l/min).

Controlled by a three-stage system adjusted by a hand-held remote, the first stage is highly effective on moderate days for airborne and surface coverage. It uses the powerful 25 hp fan and misting ring to deliver millions of fine atomised mist droplets over a wide area, which collide with tiny dust particles and drag them to the ground. For windy days, stage two features a pressurised stream delivered by the central nozzle. On high wind days, operators can use the fan, misting ring and centre nozzle for maximum coverage.

The versatility and coverage area is extended with the customisable 359º horizontal oscillation range and 0-50º vertical throw angle. Using the hand-held remote, the operator can raise the spray angle to reach extended heights, directing the 250 ft (76 m) spray to areas such as high-reach demolition or across the beam of large bulk cargo ships. The oscillation range is easily controlled with the left and right trigger of the remote control to customize the precise desired horizontal range.

Mounted on a heavy-duty roadworthy trailer for towing at highway speeds with a standard ball hitch, it can be placed by a pickup truck, skid steer or lift truck wherever dust suppression is needed. As supplied, the DB-60 Surge can run potable or non-potable water, as it is equipped with two in-line 30 mesh, 595 micron filters to avoid clogging. One filter is located at the water entry point to the booster pump, another prior to the pipe feeding the central nozzle.

After the initial setup, the DB-60 Surge requires no labour to operate. The remote control has a 1,000 ft (305 m) range, so operators using heavy machinery from high-reach excavators to front loaders can command the machine without leaving the cab.

Lewis mentioned that other options are already available, including tower mounting and a version of the company’s popular Fusion lineup, which pairs the Surge with a generator to alleviate the need for a nearby power source.

“DustBoss is known for its rugged quality and long equipment life, often described as one of the most reliable and low-maintenance pieces of equipment on any job site,” he added. “Our three-year or 3,000-hour warranty is evidence of our confidence in the products. The DB-60 Surge is designed with that same philosophy and is built to last.”

DustBoss misting cannons help curb COVID-19 spread at mine sites

Environmental, Mining safety, , , ,

BossTek’s DustBoss® line of industrial misting cannons are coming to the rescue of mines and material processing facilities looking to protect workers from the COVID-19 virus, the company says.

Originally designed for large-area dust control, this atomised mist technology is currently being used for the safe and consistent distribution of surface disinfectant cleaners (SDCs) over worksites, busy foot traffic areas and communal spaces.

Mike Lewis, VP of Sales at BossTek, said: “The challenge is protecting workers and the public in outdoor spaces by the most effective means possible, using technology that requires the least amount of human contact.

“Sending crews of people out on a regular basis to clean publicly-accessed surfaces is inefficient, costly and exposes the workers to potential contamination. Studies have shown that the distribution of SDCs evenly across surfaces can effectively reduce the presence of viral and bacterial microbes to mitigate the spread of disease. Atomised mist has proven to be a very effective distribution method.”

Lewis said the company has also supplied equipment for large operations such as mines and material processing facilities that are sanitising work surfaces before employees return to work.

Atomised mist technology disperses millions of tiny treated water droplets over a wide area to achieve effective coverage.

The heavy-duty, barrel-shaped DustBoss cannons force water through a circular brass manifold fitted with atomising spray nozzles that fracture the water into tiny droplets of 15 to 200 microns in size. The mid-sized model has a reach of up to 60 m. Using a powerful 25 HP fan that produces 849.5 cu.m/min of airflow, the droplets are propelled outward in a cone-shaped pattern. With the adjustable 0-50° angle and 359° oscillation settings, the largest model in the fleet can cover up to 31,000 sq.m, the company says.

The atomised misting cannons can be mounted on water trucks or specified in the company’s Fusion configuration – which includes a trailer-mounted cannon and genset – an effective delivery system for large-scale disinfecting work that’s portable by a pickup truck, BossTek says.

“People want to work and play in the safest environment possible and this technology can help,” Lewis said. “According to some experts, these types of outbreaks may be more frequent in the future. Having a mechanism for large-area disinfection in place that is easily dispatched to vulnerable areas to quickly stem the tide of infection from surface-borne microbes is a smart move for both public and private entities.”

BossTek powers up with Tier IV Final DustBoss DB-60 Fusion

Environmental, Mining equipment, Power supply for mines, , , ,

BossTek has updated its family of self-powered dust suppression equipment with Tier IV Final-compliant power generators, ensuring compliance in all 50 US states, it says.

A global innovator in dust and odour control technology, the company made the announcement with the debut of the new DustBoss® DB-60 Fusion™, a suppression system driven by a 25 hp (18.6 kW) electric motor paired with a heavy-duty four-cycle indirect injection diesel engine gen set.

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, according to the company.

The company’s Fusion lineup, which is permanently mounted on a rugged trailer, 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, BossTek says. “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 company added.

“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 (364 litres) 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 h, with five-year/5,000 h coverage on the electric motor and a two-year/2,000 h warranty on the generator.”

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 ft³/min (849.50 m³/min) of air flow. Atomised 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° 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 per minute (87 litres per minute) 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,” BossTek says. “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 is able to provide up to 5,834 m² of coverage.

BossTek Project Engineer Jason Lesch 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 to precisely adjust fan speed. An optional dosing pump is available for precise metering of additives to enhance particle control even further.
