About DSH:

Impact Fertilisers - bag loading using a DSH System

DSH System is being used to load fertiliser into bags.

The DSH System cleverly avoids the need to employ more complicated equipment often used for truck, rail, ship, barge and store loading applications.

The DSH - Dust Suppression Hopper (loading spout) is installed under a feed point above the target repository and kept at operating level.

A small degree of natural agitation as the hopper is filled excludes air from the material being transferred.

About DSH

Mission Statement  

To be a global leader in dust-free bulk loading systems.


To provide efficient dust management solutions for the industrial bulk loading of dry goods to the world.

Company History

DSH Systems Ltd evolved to solve a worldwide engineering problem: controlling product fallout while bulk loading dry goods.  When Ravensdown Fertiliser Co-op Ltd's plant in Hawke's Bay, New Zealand needed to suppress the dust generated by its bulk loading system, Trevor Schwass developed an innovative solution -  the DSH System.

The innovative DSH System loading spouts concentrate the stream of product into a solid column, minimising dust outfall, saving wastage and contributing to a safer and healthier working environment.  The broadly experienced engineer fine-tuned the DSH System to work at peak efficiency and now DSH is the foundation product of a successful export business. 

With global representation DSH Systems Ltd is taking another New Zealand innovation to the world.
