Our Landy screen cleaners are employed in many places to remove floating and/or suspended debris. The principle of the screen cleaner is based on a construction running along an elevated track, and consisting of a carriage and a loose grab, available in several configurations. The advantage of a loose grab is that screens of any width and depth can be cleaned. The variable track length allows positioning of a deposit at any desirable place. These screen cleaners are applied in polder drainage stations, sewage treatment plants, coarse refuse installations, barrages and dams, inlets to power and desalination plants.
