UNDERWATER HULLKS (Ultrasonic Antifouling)

The proliferation of algae  along with shellfish fouling on the hull of our ships is a persistent and difficult problem that have always existed.


Annually, all boats must be cleaned and treated by adding new layers of antifouling paints with the subsequent maintenance costs and pollution associated with this type of paintings.


Fortunately IDN offers  a revolutionary solution. The new DUMO ACM Antifouling System.


This revolutionary ultrasonic antifouling prevents the growth of algae and snails without releasing any contaminating agent; hence, it protects the environment and highly reduces  the costs  on maintaining your boat.

The new DUMO ACM Antifouling System is very easy to install. This device consists on an ultrasound transmitter and a generator that lets you control the most appropriate ultrasonic wave and optimize its performance to each circumstance.

Tested for more than two years, its effectiveness has been more than demonstrated. Its high electronic quality is able to generate the necessary cavitations  that removes algae and mollusks. In addition, studies by independent laboratories concluded that it is not harmful to marine life and does not affect the fish adversely. This is the differential factor of DUMO ACM between other solutions based on the same principle.


Among its main advantages, we highlight:


Low power consumption

Long duration

Free of Maintenance

Reduces maintenance costs

Easy to install


Sea water is the ideal breeding ground for the growth of many living organisms inside the piping and seacocks of our boat.


The obstruction of these ducts causes serious problems by overheating and deteriorating the engine and producing a significant increase in fuel consumption.


Fortunately, IDN-Naval Research & Development offers you  the best solution for this problem which is based on the controlled electrolysis of copper cations.


The effectiveness of this system developed by Proytec has been demonstrated for over twenty years.


The main difference of this antifouling solution compared to other competitive systems is the desing:  Its stainless steel head with titanium on its inside.  (Image can be seen in the figure above.)



This head has three main functions:


• Facilitates the installation and replacement of the anodes because, thanks to its design, it is only necessary screwing and unscrewing it in order to replace the anodes.  There is no need to weld or do any other kind of union.


 • Safety. They are safer because if happes a total dissolution of the anode, the titanium head would not be consumed, thus eliminating the danger of a potential leak and subsecuently eliminating any economic spending.


 • The head is reusable, which allows reducing the price of spare parts.


In addition, Proytec electronic devices are characterized by using the latest electronic generation which gives them greater reliability and makes them more robust and easier to use.


IDN-Naval Research & Development is  able to protect the pipes and  the sea inlets of aluminum boats without any risk from corrosion nor the overprotection of these parts.


This antifouling equipment consist on the following components:

Consumable anode.

copper, aluminum and iron

Regulators: Ideal

for Pleasure craft

Reference electrode: only necessary

for aluminum boats.
