Closed Loop conveyors move material through a fully enclosed tube using a continuous chain and disc, keeping product contained and away from moisture, pests and spillage. Available in 38mm (1.5″), 48mm and 50mm (2″) pipe sizes, they suit operations handling seed, feed or other product that needs gentle, enclosed transport. As with the Flexi Auger range, systems can be extended or modified with additional hardware to fit your site.
