Main features

Environmentally friendly

ECO friendly dredging landscape

Due to low fuel consumption, water injection dredger ECO 150 produces low CO2 emissions. Additionally, it transports dredged materials using natural currents & does not remove them from the ecosystem.

Budget dredger

Dredger ECO 150 design

Water injection ECO 150 is a budget dredger due to its low purchase price. Additionally, it has low fuel consumption, which results in small operational costs as well as decreased CO2 emissions.

Submersible dredge pump

Cutter Suction Dredger 300 submersible pump

Water injection ECO 150 is equipped with a submersible dredge pump, which achieves high pumping flow of high density mixture. Therefore, it has higher production rates than a regular pump.

One container transportable

Water Injection ECO 150 convertible design

This compact budget dredger can be transported in one standard, high cube (40 feet) container in an assembled state. The compact design makes it easy to transport, launch, operate & store for later use.

Convertible design

Side pontoons of ECO 150 can fold upwards. Thus, it is easy to mobilize, launch on project site & store for later use. It is extremely practical for reoccurring maintenance projects.

Optional: propulsion

ECO 150 series propeller

The dredger can be supplied with a hydraulic thruster in the back of the dredger. This makes the dredger self-propelled, resulting in easier maneuverability around the dredging area.

Water injection ECO 150 applications

River, canal & channel dredging

channel dredging landscape

This dredger is especially efficient in water bodies with currents, as this helps to naturally transport sediments along the water bed. It is environmentally friendly due to low CO2 emissions and its dredging method, which does not include material removal from the ecosystem.

Reservoir, lake & dam dredging

Reservoir, lake & dam dredging landscape

Water Injection dredger ECO 150 can remove newly accumulated silt in lakes, dams through water injection into the sediments. Due to its compact, one container transportable size, it is easy to mobilize & launch on site, as well as to remove & store for later use.
