Contact SupplierWe are the leading designer and installer of screw turbines as well as having designed and installed many higher head systems using cross flow.
Our new renewable energy turbine has a number of advantages over conventional turbines.
Fish and other small species screening can be a stumbling block with many systems, and can contribute to both the capital costs and the ongoing costs. The usual need is to exclude all fish as far as reasonably possible – sometimes meaning screen mesh sizing of as little as 3mm is requested. This can make a conventional turbine unworkable, but with the slow turning Screw turbine it is possible to simply let the fish through. There are no trapping points for the fish and no pressure discontinuities which can upset them also. Installation can be relatively simple, and costs can tend to be lower on low head sites, for instance on the many river weirs which exist. There are few moving parts, so less parts to get damaged and go wrong. And unlike nearly all turbines, you can see the water doing the work.
