VORTEX 3" Dredge
'GUST to STORM'

Maximize diver bottom time.

The VORTEX 3-inch carries the same patent pending technology as our 4-inch range of dredges making this the most powerful 3-inch ROV and diver dredge in the world. Smaller ROV not previously able to bid on work with dredge, now have a variety of dredge choices.

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. Our 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.

Our environmental concerns are addressed through high efficiency, low energy demand hydraulic system negating the need for external compensators.

Our clients have been considered with the most complete dredge system available on the market today.

Why is Vortex Dredge Superior to other ROV Units?

Vortex dredges have been designed to combine high suction values and high water volumes to tear up sticky soils with very high suction then keep it flowing with high water volume. Powerful, simple, effective.

Example: Getting a "RIDICULOUSLY THICK MILKSHAKE" ® ™ to move through a straw is similar to dredging a very sticky seabed and suction is key because if you drive a suction hose deep into sticky mud the water flow in the suction hose will often stall and the hose is essentially filled with a 'plug' of mud and only high suction will clear the hose. Once the hose is clear then water flow takes over. Suction does the work and water flow continues the work done.

VORTEX performance figures DO NOT have a small print clause with an Asterix symbol next to figures which would represent "best case Scenario" removal rates as opposed to actual removal rates.

VORTEX removal rates are ACTUAL removal rates as seen with actual material moved using Magnetite black iron sand and rocks weighing 2.375kg per liter as to the sample product.
