Why Choose a DSH?

  • Protect the Environment

    With a DSH, harmful dust is prevented from escaping during loading or transferal, which improves both air quality and visibility on worksites as well as in surrounding areas.

  • Lower Maintenance

    With no internal moving parts, electricity, hydraulics, or pneumatics required, DSH's need less maintenance over other systems, and any servicing that is due is a simple and quick task.

  • Outdoor Spaces icon

    Less Health & Safety Issues

    By reducing the amount of fugitive dust released in the workplace, DSH's help create a healthier, safer environment, all whilst and ensuring health safety protocols are met.

  • Custom Additions icon

    Reduced Waste & Cleaning

    DSH's keep dust particles condensed within the material itself which prevents fugitive dust from escaping, leading to less product loss, reduced waste, contamination, and housekeeping.

  • Preserve your Product

    DSH's keep product safe by protecting the integrity of blends and mixes and/or preventing damage to delicate items during loading, and ensuring all of the product gets loaded.

  • Autonomous

    Operating completely autonomously using its spring system, the DSH reduces the need for constant supervision and adjustments, allowing for faster loading and reduced personnel input.

What Our Clients Say

  • DSH Systems dust suppression hopper can achieve major reductions in fugitive dust emissions and also dust explosion hazards. It will be a very useful tool for many bulk handling engineers and technicians.

    Associate Professor Peter Wypych, Centre for Bulk Solids and Particulate Technologies, University of Woollongong, Australia

  • We bought our first DSH hopper in 2007 and now have four more installed. It has allowed us better control over our dust and required no air, hydraulics or electricity. There is no waste dust stream to handle and our load rate was not impacted at all. We had our first spout up and running in 30 minutes! I had my doubts when I first saw the before and after pictures, but the system really does work that well!

    Lisa Brickey, Mosaic Crop Nutrition, USA

  • For 28 years I haven't seen anything that can control grain dust from that height when hitting the ground. It is a huge improvement from what it was without the hoppers. Safety wise, guys wouldn't go into the plant, we had to do something drastic really quickly. This has turned it around overnight for us, they are doing a fantastic job and we're really enjoying it.

    Garth Gillam, Goodman Fielder, New Zealand

  • We have had the Hopper operating for about 7 months and are extremely happy with it. We now have basically no maintenance to worry about. We no longer have to reline the old system every 3-4 months and no more electrical concerns, re winches etc, that used to raise and lower the old chute. I anticipate that we will be installing more Dust Suppression Hoppers on site in the near future

    Karl Van Wanrooy, Incitec Pivot Ltd, Australia

  • Impact Fertiliser, the preferred supplier of nutrients to Tasmanian agriculture, installed a dust suppression hopper at the Devonport site two years ago. Since then we have installed three more at depots around Tasmania and others in Victoria. All Site Managers are more than pleased with their performance.

    Breven Howe, Impact Fertiliser, Australia

  • The Hopper has made a big difference on the super line at Geelong in the short time it has been operating, mainly in the time it takes to load. I estimate that it is four or five minutes faster as we do not have to take the crossbars out of the truck bodies, or if they are left in, the old chute had to be raised and lowered into each section and now it runs straight through the whole length and does not make any dust. Hopefully every fertiliser company will be using them soon.

    Steve Johnson, Elders WGF, Australia

  • Ravensdown Fertilisers, Severn Street Store have had the privilege of using and installing a Dust Suppression Hopper (DSH) which has been able to fulfil our store requirements for dry, dusty, granular, and powdered product. Allowing us to contain dusty product is paramount to our operation, as is the flow of material when loading bulk trucks from our site.

    Severn Street Store, Ravensdown, New Zealand

  • We have one of your hoppers operating at Port Adelaide on straight Urea (commissioned in 2005) And I am very impressed with it. Didn't think anything would do that after thirty years in the business.

    Robin Douglas, Incitec Pivot Ltd, Australia

  • In my 30 years in the grain industry, my observation was that the hopper worked well to reduce the dust levels to well below what would normally be expected.

    Andrew Kotzur, Kotzur, Australia

  • The DSH worked better than expected.

    Danae Gonzalez Baron, Gonbar Constructora, Mexico

  • We use the Dust Suppression Hopper on our load-out points'; truck and rail and also the dress belt into store, a drop of about 14 metres. The hoppers have been a great success in cutting down the dust problem and make visibility a lot easier and provide a perfect pour when loading. Not only are we happy, but truck drivers and transport companies are thrilled as there’s less debris over their trucks. The computer-controlled model pours perfectly every time and is great for loading spreaders with small bins.

    Hugh Eaglesome, Ravensdown, New Zealand

  • We load 120,000t of single superphosphate for bulk shipment and around 200,000t for truck/container, which generated localised dust, and resulted in complaints and OH&S issues. Installation of DSH hoppers at 12 locations around Australia has resulted in significant reduction of fugitive dust emissions, a significant improvement to the working environment and zero dust complaints, achieved with zero impact on loading speed and in some instances, an increased loading rate. The new system has been embraced by all parties and now constitutes standard practice.

    Grant W Allen, Impact Fertilisers P/L Australia

  • We've just installed a new DSH spout at our feed phosphate load out. WOW!! The dust control is amazing! We LOVE it!! It doesn't seem to matter how far the product falls, no more dust is created and the tube of product that comes out of the spout is narrower, making it easier to load pneumatic trucks. No electricity, no moving parts, $ investment, results.... Priceless!
