Atlas Polar - Model Single Boom ST9000 -Hydrorake Trash Raking System
The Atlas Polar trash raking system cleans any gauge screen or bar rack. Installation upstream provides space for trash removal and deck access for personnel. The fully automatic system replaces handraking, which is still the most common method of rack maintenance. The Hydrorake imitates this action automatically 24 hours a day even in the coldest weather. The PLC control system comes complete with HMI screen. Permits tailoring the operational sequencing to any flow or debris conditions at each intake. Multiple units can be used on the Hydrorake rail system for intakes with large masses of debris such as the USBR fish screen protection barrier in central Washington state.
