Improved airborne dust and fly ash suppression systems

COLDMist dust and odour control technologies has been appointed exclusive Australian agent for both the Probe and Penguin /Proptec range of water fracturing systems for improved dust suppression results. These revolutionary rotary atomisers use a rotating metal gauze cylinder to create droplets of uniformed size. The rotary atomiser works by injecting water into the cylinder head spinning at 12,000rpm, and fragmenting the liquid into an incredible 238 billion droplets per litre - each uniformed droplet 20µ in size. Any industry that requires dust control can benefit from the ColdMist range of Probe dust control products. Using the oscillating option, up to 465m² (5,000ft²) can be dust controlled, odour controlled and cooled off at the same time.

The Penguin & Proptec series atomisers give high volume, ultra-fine mists that disperse quickly. With incredible ease of installation and use, they have a simple single or three-phase motor, meaning there are no sophisticated controllers or electronics involved. Simply wire in the atomiser, plumb a water line, and they are ready to work. Available in single-phase or three-phase 240V / 415V - both hydraulic and pneumatic units available too.

Rotary atomisers have the following advantages

• The consistent spray pattern and uniform droplet size formed by the rotary atomiser result in a dramatic increase in efficiency . Using centrifugal force to create the perfect droplet size reduces wasted liquid which is produced by conventional nozzle systems. Large droplets waste water because they do not adhere to particulates in the air and fall to the ground too early. On the other hand, droplets that are too fine can drift away from the target area and evaporate too quickly.
• The Probe rotary atomiser comes with a flowmeter as standard, which allows a variable flow of liquid into the Rotary head. The flow rates can be regulated from 1 Lt/hr up to 180 Lt/hr easily and quickly. This unit effectively covers an impressive range of up to 30m.
• The rotary atomisers are quickly and easily installed and have the advantage over conventional nozzle-based systems as little or no maintenance is required.
• Virtually clogproof and unaffected by wear ,there is no need for a filter and they utilise minimal water and electricity.
• Rotary atomisers only require water delivered to them at normal supply pressure thus bypassing the need of expensive supply or booster pumps

COLDMist atmospheric cleanser for increased dust absorption

The Probe rotary atomiser, used in conjunction with the Airopure atmospheric cleanser, can increase dust absorption by up to 400%. This surfactant greatly improves binding of dust particles creating a powerful and effective combination for dust or odour control. Disinfection of the water supply has the added advantage of reducing the risk of contamination by pathogens such as Legionella. Airopure is 100% biodegradable, odourless, and harmless to humans and animals.

High-pressure nozzle systems

COLDMist Cooling offers a range of pumps / controllers which are the core of each high-pressure, nozzle-based misting system. The result is a water droplet size of 8-10µ. Optional UV filters sterilise the mist/fog eradicating microbiological contamination which may be present in the water supply. The company provides a selection of misting systems to suit any size application. A professional installation service is also available on request.

Heavy-duty industrial cooling fan

Our robust industrial cooling fan helps meet current OH&S obligations which require that workers working in heatstress conditions are given pro rata rest and recovery periods. Providing workers with an effective cooling system will improve worker comfort and boost productivity levels. Our 1,250mm diameter l, low-noise fan exchanges 35,000m³ of air per hour and comes complete with a 28-nozzle mist ring matrix fitted to the front - supplying phenomenal cooling power.

Mobile fogging systems

The COLDMist Aquafog mobile fogger is compact, sturdy and enormously powerful. Uses include: large-scale humidification, fumigation, evaporative cooling, and industrial spot cooling, to name a few. The pivoting fogging head allows you to direct the fine-mist fogging output right where you need it.

Suitable for indoor / outdoor use, units are fully adjustable with fogging capabilities up to 106 l/hr. These foggers propel a powerful jet stream of misty-fog up to 35ft in distance. The 68 Lt reservoir tank with large mouth opening is ideal for adding liquid chemicals for fumigation and sterilisation applications. An internal float valve assembly with garden hose connection allows for continuous duty application.

COLDMist large area dust suppression and odour neutralisation systems

In the case of large areas such as demolition sites, quarries and stockpile operations, volumes of dust are generally greater, and, as such, an increased volume of water droplets is required. Where increased area coverage is required , the extensive propulsion of the mist is achieved utilizing COLDMist's barrel fans. Originating from the Snow Making Machine industry, all these systems have been submitted to rigorous testing in the most extreme environments to guarantee their excellence today . Simplified, they are 'monster' fans with nozzle rings mounted in front. A high pressure booster pump pressurises the water which is then fed through the nozzles. The resultant spray plume is propelled forward by the barrel fan. Water throughput can be up to 90Lpm. The Coldmist range of delivery systems from Duztech of Sweden are loaded with features, including:

• Rapid, servo assist oscillation up to 330 degrees
• Manual or servo assist tilt up to 60 degrees
• Up to 80m throw
• Adjustable water output
• Large size dirt filter
• The new Duztech machine range is currently the only system in Australia with unique remote control operation !
• Choice of skid-mount or trolley mount

COLDMist 's dust control solutions have recorded outstanding results - the largest unit capable of blanketing 125,000ft² with a fine mist of water droplets when equipped with optional 350° oscillation. This ultra-fine mist attracts dust and odours encapsulating airborne particles and driving them to the ground, ensuring continuous compliance with the toughest EPA air quality standards.

The systems will help stabilise surface dust and prevent migration of dust during extraction, crushing, loading or transporting of material. reducing the risk of dust-related complaints and potential fines, health and air quality concerns. The ultrafine mist generated by the units will not over saturate the target material, ensuring the quality of your end product won't be compromised. It can even be used to condition aggregate for use in concrete, including concrete curing.

The ColdMist Dust Dominator has been designed by quarry people for quarry people

This stainless steel ring creates a wrap-around curtain of mist to contain fly ash and airborne dust at material transfer points and stock piling conveyors on crushing and screening plants. The Dust Dominator can be fitted with a range of different nozzles specific to a project. Available in a range of sizes according to the scope of the job , the system may also be configured to suit the operator's requirements - quarter section, half ring, three quarter ring or full ring. This system is both cost effective and energy efficient - requiring only mains water pressure - no electricity necessary! An optional booster pump option will achieve higher water pressures if required.
