It all began with a question.

DSH hopper systems are the invention of Trevor Schwass, who was asked to formulate an idea to aid in reducing dust and improve the air quality at a fertiliser plant in Hawkes Bay, New Zealand.

The site was suffering from huge amounts of dust that was created during loading, that engulfed the yard and made machinery and workers almost invisible in the murk. So, In 2004, after several years of designing, tinkering and fine-tuning, our award winning dust suppression hopper was born. Trevor managed to create a simple, autonomous systems that required minimal utilities, maintenance or expertise to install, and the “magic bucket” has been clearing the air ever since.

Since then, DSH has installed thousands of hoppers across 40 countries and now has a global distribution network. Not bad for a clever kiwi bloke!
