Water hoses, sprinklers and nozzles are a thing of the past
TERA dust control units
Water hoses and sprinklers were once groundbreaking technologies in the world of dust control. While both are excellent for watering plants and fighting fires, they are unfortunately less suitable for large scale dust control. As a result, water cannons have often been used in recent years. Most machines are fitted with nozzles, through which water is forced at high pressure. This solution is now out of date and wastes an enormous amount of water and electricity. What is the current trend? Which solution is popular nowadays?
Since 2010, Dehaco has designed, developed and produced a different solution. Instead of nozzles, Dehaco's dust control units use a rotor. The rotor technology is a unique development in the field of dust control. These machines are suitable for any conceivable application, from demolition to waste management, firefighting or transshipment of bulk goods. The rotor prevents two major drawbacks: blockages and excessive water consumption.
Blockages
Dirty water or hoses can lead to blocked nozzles. The opening of these nozzles is a small as the tip of a ballpoint pen: around 0.5 mm. This means any object larger than this can block the nozzle. If a nozzle is blocked, work must be halted. Downtime can mean deadlines are not met and can lead to high costs.
The smallest opening on the Tera is 3 mm. This means blockages are almost impossible. Any blockages in the water flow can easily be removed from the rotor, which allows the work to continue uninterrupted.
Water consumption
In the past, the performance of nozzles always decreased if the water consumption was reduced. The rotor always works, regardless of the volume of water supplied. The 400V range of misters always spread perfect water droplets, whether the water flow rate is 100, 500, 1000 or 4500 litres per hour. Because the water flow rate does not affect performance, the droplet size can be adjusted by turning a switch.
The spinning rotor literally cuts the water into droplets. It works perfectly regardless of the supplied water pressure. Expensive and fragile water pumps are no longer required.
Dust emissions
There is increasing concern about harmful, carcinogenic dust emissions, and a good dust control strategy is more important than ever. Demolition sites, mines, waste processing facilities and commodity processors must reduce their dust emissions to protect their employees, the local population and the environment.
Legionella bacteria
Airborne bacteria are a common topic of conversation and affect our daily lives more than ever. Legionnaires' disease has claimed lives every year since 1976. This illness is caused by the legionella bacteria and is spread by water droplets in the air. This is precisely the method we use to control dust.
UV-C lamps
To prevent this, Tera dust control units can be fitted with UV-C lamps. These lamps destroy the bacteria before they reach the rotor. The unique feature of this system is that the power and quality of the UV-C light can be measured and a visual indication given of the performance. This means you can be sure that the water is disinfected optimally.
All shapes and sizes
Dehaco manufactures a complete range of dust control units. With ranges from 5 to 90 metres, Dehaco offers the perfect solution to dust emissions for interior demolition and renovation, as well as expansive sites and demolishing tall buildings.
Our well-designed, high-quality dust control solutions, including the Tera range, are becoming just as important as all other personal protective equipment. In the near future, you may not just pick up your helmet, earplugs and safety glasses at the start of your shift, but also the keys to a Tera water mister!
