Amazing professional marine testimonials

No barnacles, no algae, just dead biofilm, easily removed by a high pressure cleaner:

yacht Gulliver (equipped with Harsonic ultrasonic transducers): just out of the water, after 30 months:

A diver inspected the boxcoolers of the URS-Smit tugboat Union Panda after a 14 months NO CURE NO PAY BiofilmFree^© with Harsonic® installation:

< Dear,

We did indeed dive on the Union Panda to have the condition of the box coolers checked 14 months after installing Harsonic. The only thing we have seen is a very limited layer of biofilm on the tube bundle and cabinet. No smallpox, mussels or algae were visible. This was a very good result.

We do not have a report on this yet.

Best regards
