Suction Dredgers
A suction-type dredger is often the ideal solution for dredging relatively loose and free-flowing material. The ROHR-IDRECO suction dredgers are electric driven (diesel/diesel-electric drives are optional), and our advanced automation and monitoring software, developed in-house, ensures the highest efficiency and the lowest possible energy consumption.
Further benefits include reduced wear and tear on pumping equipment, a low carbon footprint and minimal noise pollution.
Low carbon footprint
The ROHR-IDRECO jet suction dredgers are electric driven (diesel/diesel-electric drives are optional). This ensures the highest efficiency and the lowest possible energy consumption.
