Trash rack cleaning

Ossberger is also specialized in the construction of both stationary and moveable trash rack cleaning systems. They are indispensable for a safe and long-term electricity production of hydropower plants. The systems clean protective screens of water supplies from washed up debris, ensuring a maximum flow rate in the turbine. The systems are quick and easy to install, particularly reliable and only require low drive power. They are a profitable investment for any size of hydropower station, paying off after a short time already.
