Why Choose a DSH?
The DSH
Difference
Our philosophy is to prevent the generation of dust at the source, before it enters the environment, rather than trying to remove or suppress it after it has escaped into the air.
Our system is an effective, low cost, low maintenance, long term solution to prevent fugitive dust. It is easy to install and can be used with various bulk loading systems and dry, free flowing materials.
Clearing the Air since 2004
Proudly designed and made in New Zealand, our systems are available worldwide through our trusted global distributor network.
How It Works
The DSH hopper is installed under a loose bulk material infeed point, where it is suspended in a fixed location above a receiving vessel or loading area. As the hopper fills the product level rises, and the springs extend progressively opening the flow control gap and balancing the product flowing in and out of the hopper.
Our unique design expels air and forms an annular flow that is then compressed radially into a solid column as it exits the hopper. The solid discharge column falls through the air virtually dust free for many metres, before driving into the pile formed on the floor or in a receiving vessel, resulting in minimal dust release and product loss
