Model DWA-7    Dredge Works Production System

In 1985 the concept of velocity control on a dredge was born.  In partnership with Toshiba engineers, this system used their VFD drive with a customized flow control system. This proved our concept and was the start to our current production system.  Just one of the two tools for maximum production. The other is maximum density that can be hydraulically transported by our density control system. Our current generation 7 system is the solution to maximum production.  Constant target velocity at maximum achievable density is the key to top production. This is even more necessary in underwater pump dredges. You are now able to reach higher density that can be hydraulically transported by the dredge pump. Now the true limit of a dredge’s potential can be reached. This can only be achieved with automation. The adjustments made when at high density by our automation system is far more than any dredger could accomplish. This is where we differ from the competition. The DWA-7 system does not work on dilution of slurry and limiting production. With our velocity control the max achievable density is reached due to the pump being able to increase rpm when needed. The dilution valve is now used in a different way. Now used to only open the valve when max achievable density or other critical parameter is reached. Our system uses density as one of the valve functions. Now the real limit of a dredge can be achieved. A twenty percent increase in production is not uncommon. Our system is an all-in-one panel. The computer processing unit and dash panel are all in the same panel with no extra boxes.  System includes bypass dilution valve, main panel, engine monitoring, sensors, and density system.

You have a valve, no problem and this could save you money. Although we may need to add the density feature to your valve if you have an underwater pump. Give us a call!
