KK-CROV-T8-EX 8 Propellers ROV with 300m Working Depth

KK-CROV-T8-EX eight propellers ROV is a specialized system engineered for underwater observation and operations. Powered by electricity, it combines a precision-engineered structure, robust dynamic performance, and versatile operational capability to adapt to a wide range of underwater monitoring tasks—delivering stable, clear, and comprehensive underwater data support to users.
The ROV adopts a scientifically calibrated balance between its center of gravity and center of buoyancy. Its thruster configuration follows “four-vertical, four-horizontal”, delivering powerful thrust and strong resistance to turbulent flows for stable three-dimensional underwater movement. The four vertical propellers enable controlled in-water rotation, allowing cameras to capture precise, targeted imagery.
