ND-ULTRA Twin Transducer Ultrasonic Antifouling System



A powerful and very high quality twin-transducer ultrasonic antifouling system for marine vessels from 35′ to 50′ approximately.

SKU: ND-ULTRA Category:


This is the latest version of the ultrasonic antifouling system I had started developing in 2014 and that was documented in these articles:

Ultrasonic Antifouling System: Part 1, Development & Construction
Ultrasonic Antifouling System: Part 2, Fighting Algae Growth

Please note that it is not always available, because it is quite time-consuming to build. They are manufactured in small batches and listed here because people were asking about purchasing it by e-mail. We have shipped them worldwide since 2018.

This system has proved to be superior to many high-priced commercial offerings. Ultrasonic antifouling is still an active area of research and development, with trials usually underway and incremental product improvements. This is third generation hardware, completely redesigned in 2021 to meet extended functional requirements.
