VORTEX 4 Inch Dredge 

The most powerful 4-inch ROV and diver dredge in the world, the VORTEX 'Tornado' 4-inch dredge is capable of a near perfect vacuum of 97kpa (28in/hg) - which to our knowledge, is unheard of with dredge equipment. 

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

Our client's have been considered with the most complete dredge system available on the market today.
