SKU: ND-ULTRA Category:


This is the ultrasonic antifouling system I developed and 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 and I don’t always have transducers in stock. I sometimes manufacture small batches of them and I have listed it here because a number of people have asked about purchasing it by e-mail. I have shipped them to New Zealand, Australia, Europe and North America.

So far, this system has proven to be superior to many high-priced commercial offerings. Some experiments are still in progress on test case vessels and I may still improve it if an opportunity arises.
