With our ultrasonic devices positioned inside the hull of your ship, mussel and smallpox growth become a thing of the past.

Perpetual issues, we’ve got the solution

For more than a decade we’ve embedded research to understand the reactions and use of liquids, starting from the root cause of our problems. This root cause is the biofilm. We have unravelled this micro-organism and incorporated the findings into our product as a craft. The most averting problems are listed here.

Sea-fouling on the hull

The growth of algae and barnacles on the underwater ship creates friction that slows down a ship. The sea fouling commences from forming its roots in the biofilm. After every season, cleaning with high pressure and chemicals is required. Afterwards, a new primer and antifouling is required during each maintenance procedure.

Mussels & pox on hull

Barnacles attach to the hull due to the presence of biofilm which is the food source of these harmful organisms. They can create holes in the hull of a ship and make costly damages.

Reapplying Antifouling

After each season, a boat must come out of the water to clean from algae, barnacles, and mussels. Usually, they use hydrochloric acid and sanding machines which also destroys the antifouling and primer. Therefore, a new primer and antifouling needs to be reapplied every year.

Damaged Propellors

The ship’s propellers may be affected by fouling from algae, mussels and smallpox. This causes a loss of speed and high maintenance procedure.

Clogged Fuel filters and tanks

The filters and tanks of drinking water and fuel can become clogged with bacteria, limescale, and corrosion. This results in a lower flow rate and higher energy use which affects the lifespan of the system.

Contaminated pipes and tank

Tanks and water lines on board can develop bacterial buildup. Various water pipes and water tanks can also contaminate by all kinds of bacterial accumulations. Legionella is a common problem on offshore marine. It can cause serious illnesses of personnel and a growth of overhead costs.

Fouling on the box cooler

Algae, mussels and smallpox can attach themselves to the ship’s box cooler. To clean and maintain the coolers, the ship has to go ashore and requires heavy maintenance procedures; often with dangerous chemicals. This doesn’t only requires long cleaning services but is also very expensive after all. Additionally, the fouling will reappear constantly since its food source isn’t eliminated.


We offer custom-made, high frequency, ultrasonic transducers for ships. The devices are glued to the inside of the hull, below the waterline, and combat biofilm in fuel tanks, water tanks, pipes and any other water system to keep them bacteria and lime-free. What’s more, they also eliminate mussel, shell, algae and smallpox growth.

We adapt our products to the conditions and structure of the intended location, making sure they perform flawlessly.

Installing an ultrasonic device

Ultrasonic devices require a specific glue that is included in every order. This glue allows the vibrations to pass through. You can easily install the device yourself. If you choose to do so, we will check and approve the installation.

I would recommend Ultrasonic Group to everyone with a sailboat. It saves me on yearly maintenance costs in a eco-friendly matter.

Fishing Pond
I had a lot of issues with thread algae in my pond but after one month with the system of Ultrasonic Group, I could easily scoop out the algae and could finally see the bottom. After 6 years, I never experienced any problems anymore.

Swimming Pool
I had a slight bit of ‘green’ on some of the floor/walls of my pool. This now seems to have gone, forever.

With the devices of Ultrasonic Group, my antifouling has been there for 5 years straight, and the boat is still clean without being replaced or taken out of the water!

The device installs quick. Now I don't have to clean my jacuzzi every two months and can leave it as it is without adding any chemicals to it.

I had a fully personalised service for my swimming pond. A fantastic product with great results, and it doesn't harm my fish but actually creates a better environment for them!
