A jet suction-type dredger is often the ideal solution for dredging relatively loose and free-flowing material. The ROHR-IDRECO jet 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.

The standard DRAGA dredger range up to a digging depth of 55 metres is built fully containerised to ensure low-cost transportation worldwide and allow delivery to inland (sand and gravel) mines and hydroelectric locations with often limited accessibility. Later relocation of dredgers to other sites is facilitated through our iPlug-and-Dredge Concept.
Open product infoThe modular design ensures industry-leading delivery times and a continuous availability of parts. Full customization is possible through extensive choices on for example the iPump® type, excavating grinders and other add-ons, and levels of automation, monitoring and visualisation.
ROHR-IDRECO can install a measurement and visualisation system to optimise the mining production. This is done using DGPS receivers, several sonar sensors (pressure, inclinometers etc.) and a proprietary software system that measures the operating point of the suction head or grab. This virtual real-time system helps minimise any dredgeable material left behind by the operator. In combination with the revolutionary ROHR-IDRECO iDredge system, the dredger can even be turned into a (semi) automatic and remote-controlled machine.
