In 2006, NRG Marine set out to develop an environmentally friendly antifouling technology against a backdrop of increasingly stringent legislation governing the use of poisonous biocides in marine coatings.

After 2 years of extensive R&D, Sonihull was born. Based on the same ultrasonic technology that has been protecting the food, brewing and hydroponic farming industries for decades, Sonihull is the eco-friendly antifouling solution that the marine industry has been waiting for.

Sonihull has now grown into a complete range of fit-and-forget ultrasonic antifouling devices for any solid surface that is exposed to raw seawater. With a wide range of surface-mounting adaptors, Sonihull can now protect every part of your vessel and structures from marine fouling. From hulls, shafts, propellers and waterjets to sea-chests, tanks, keel-coolers, box-coolers, heat exchangers, pipework, intakes, and valves.

Sonihull keeps algae, weeds, barnacles, and mussels away season after season in all kinds of fixed and mobile marine structures, from fish farms to superyachts. Our technology reduces the marine industry’s dependence on poisonous chemicals, expensive cathodes and toxic paints while simultaneously reducing environmental impact and lifetime maintenance costs.

With continued R&D, Sonihull is now in its 4th generation and there are 30,000 units installed worldwide. The Sonihull 4.0 is the only system in the industry to incorporate full critical path monitoring and PLC integration. It is also the quietist ultrasonic antifoul system in the world to date.

Over the years, the NRG team has amassed a wealth of experience at the forefront of ultrasonic antifouling and are on hand to answer any queries and assist with any applications you may have. To know more, visit www.sonihull.com.
