B + W launches ‘Naltec’ spray cannons

B + W Gesellschaft für Innovative Produkte has expanded its Naltec water fog system range with the launch of new spray cannons. This type of product generates fog with super fine floating water droplets generated at a low energy consumption with a working pressure of 10bar, according to B + W. The fine nebulisation makes it possible to economize the water consumption which leads to a decrease in energy and operating costs, with the mobile and stationary structure being adaptable to local conditions. The fans create a fine water mist that is blown over a long distance, and by tilting to 350°, all round fogging and wetting of a large area is possible. Depending on the requirements, there are different varieties which differ in the throwing distances and amount of water sprayed. In windless conditions, a throw distance of 15m to 200m of the fog flow is possible. The model has a steel construction, and basic equipment includes a fan with diffuser, nozzle ring in stainless steel, frame with rotary actuator, pump with filter and controller with dry run protection. Other accessories, such as a three wheel undercarriage, remote control, trailer, water tank and power generator, are suited for individual requirements. The Naltec spray cannon is independent from the water and power connection, and by using the trailer the spray cannon can be used in any location.

Dynaset presents new kits for its ‘HPW-Dust’ system

Dynaset offers new kits for its HPW-Dust high pressure dust suppression, a dust control system for mobile machinery in fields such as demolition, crushing and recycling. The different accessory kits include connectors, nozzles or filters, available for a variety of machines. The HPW-Dust system produces atomised water mist to suppress dust. According to Dynaset, the dust suppression effect binds the dust with minimal water, and a smaller drop size binds more dust particles and improves dust suppression when compared to low pressure dust suppression systems. Its nozzles are installed either at the end of the excavator's boom or directly on the demolition tool. That way, the atomised water mist is targeted where the dust is emitted, and the particles are trapped under a cover right after creation. With HPW-Dust, the user can drive the machine to the side of the building, connect the inlet water hose or fill up the water tank, and activate the dust suppression system from the cabin when needed.

BossTek introduces upgrades with ‘DustBoss DB-60 Surge’

BossTek has introduced a pair of upgrades to one of its advanced dust suppression cannons in a move to enhance its power to cut through difficult wind conditions and deliver particle management. The DustBoss DB-60 Surge features a new, adjustable high pressure centre nozzle, designed to give operators more control over the dust trapping water plume. The re-design is engineered to provide multi-step, variable flow dust control, and the single centre nozzle allows users to fight wind or pinpoint a long reach target for dust suppression at the point of emission, while minimising clogging and maintenance.

Another update is the addition of a ‘Variable Frequency Drive’ (VFD) pump to the ducted fan and misting ring design. The VFD smart pump technology allows the machine to react to specific water delivery capabilities, and senses when the water supply is unable to keep up with demand and automatically lowers the flow to keep the machine running. Fed by a standard 38mm hose with a cam-and-groove quick disconnect coupling, the booster pump delivers up to 27.5bar of water pressure to the centre nozzle. The centre nozzle also has a variable spray pattern, from tight jet stream to a wider plume, and can be modified remotely or on the unit. It can be coupled with the optional filtration system for non-potable water. The model features remote control from up to 305m away, and custom oscillation ranges can be created from local controls or the remote. The model will retain the three stage performance options, so that users can operate with the misting ring alone, the centre nozzle alone, or both together.

The model is equipped with adjustable elevation from 0-50° and 260° oscillation, and is capable of delivering more than 8,000m² of coverage. According to BossTek, the pressurised spray resists wind shear and uses the force of the wind to further fragment and propel the droplets, while the misting ring delivers a variable pattern of millions of tiny droplets to suppress both airborne and ground level dust. Mounted on a trailer for towing at highway speeds with a standard ball hitch, it can be placed by a pickup truck, skid steer or lift truck. After the initial setup, the model requires no manual labour to operate. Other options are available, including tower mounting and a version of the ‘Fusion’ line-up, which pairs the Surge with a generator to alleviate the need for an accessible power source.
