Dust Suppression Hopper DSH

Patented autonomous technology dust suppression

Development of the New Zealand company DSH Systems – DSH dust suppression hopper – a device for reducing dust formation when reloading dry, granular and bulk products.


How it works?

The DSH hopper is used under the central feed point. It compacts your product into a reduced volume flow, eliminating air from the conveyed material, allowing it to fall freely to any loading point with minimal dust particles being released. Suitable for loading the product into warehouses, big bags, ships, open and closed transport.

How difficult is installation?

All installations are tailored to the needs of our customers. In most cases, the DSH hopper can be easily integrated into existing loading facilities with minimal time required to upgrade the technology. The system does not require electricity, compressed air or frequent maintenance. Where site-specific design is required, we develop a unique solution to ensure the system performs to your expectations.
