Vortex 4” Dredge ‘Standard’

Available to rent exclusively from Ashtead Technology, the most powerful 4-inch ROV and diver dredge in the world, the VORTEX has removal rate performance more commonly seen in 6 inch dredges.

The option of a jetting head kit is included, after extensive development to ensure there is no reduction in water flow to the dredge unit which can reduce available working vacuum.

The low hydraulic consumption leaves enough hydraulic supply on most ROV’s to utilize a purpose built high pressure jetter unit if the task requires one.

Operator safety has been considered with use of large, yellow name tags on all high pressure fittings and minimal component weight and comprehensive manuals.

Environmental concerns are addressed through high efficiency, low energy demand hydraulic system negating the need for external compensator’s.
