ROHR-IDRECO dredgers are (as standard) electric driven, and its
advanced in-house-developed automation and monitoring software ensures
the highest efficiency for the lowest possible energy consumption. Further
benefits include reduced wear and tear on equipment, a low-carbon
footprint and minimal noise pollution.
The Netherlands is famous for its battles against the sea and water, and
ROHR-IDRECO can leverage on centuries of world-renowned Dutch and
German dredging and engineering expertise. This is combined with sixty
years of in-house experience in sand and gravel extraction.
ROHR-IDRECO is committed to developing innovative and sustainable
vessels and equipment by combining ingenious design with the latest
technological advances and highest quality materials of European origin.

ROHR-IDRECO’s creative, proactive and forward thinking approach to automation is at the core of its activities. The company has invested considerable
R&D resources into its (semi)automatic and remote-controlled dredge systems, resulting in the revolutionary iDredge® concept.
This smart approach to dredging systems also includes the option for detailed data collection and automated analyses on performance. This allows
ROHR-IDRECO to offer customers bespoke advice on how to increase efficiency and reduce power consumption. Tailor-made programs for the timely
replacement of consumables or maintenance are offered, keeping down-time to an absolute minimum.

THE NAME OF THE GAMEFLOATING CLAMSHELL DREDGERSROHR-IDRECO floating clamshell dredgers are designed to extract sand and gravel from 10 to 180 metres below water level. All dredgers are
custom-built to the requirements of each deposit and the needs of every customer. Customers can choose among various components for
on-board processing, such as double or single-deck screening machines, crushers, fine sand recovery, conveyor belts or hydraulic transportation
to site. Two types of hydraulic motor grabs manufactured in-house complete the package and make the dredger an efficient tool for every purpose.
BUCKETLADDER DREDGERSThis type of dredger is also designed for the extraction of sand and gravel from wet mining pits and comes in both a land-based and floating type.
The dredging depth of bucketladder dredgers varies from 0 to 14 metres for the land-based models and from 6 to 24 metres for the floating
models. Similar to floating clamshell dredgers, floating bucketladder dredgers are equipped with an on board processing plant comprising a
double or single deck screening machine, crusher, fine sand recovery, conveyor belt or hydraulic transportation to shore.
JET SUCTION DREDGERSROHR-IDRECO standard dredger range is built fully containerized to ensure low-cost transportation worldwide and allow delivery to inland (sand
and gravel) mines and hydrodam locations with often limited accessibility. Relocation of the dredger later on to other sites is facilitated through the
iPlug-and-Dredge Concept. Through the modular design, ROHR-IDRECO can ensure industry-leading delivery times and a continuous availability
of parts.
Full customization is possible through extensive choices on for example the iPump type, and levels of automation, monitoring and visualization.

If the software is the brain of a dredger, the pump is its beating
heart. ROHR-IDRECO has had its own complete iPump® line for many
years, developed for high-performance operation and efficiency.
The iPumps are wear-resistant for an increased life span, have optimal
suction characteristics, are energy efficient, and can be adapted to a
wide range of tasks.
