Ultrasonic Antifouling Overview

Any vessel exposed to seawater needs to be protected from biofouling. The buildup of weed, algae, barnacles, plant matter and other marine fouling drastically effects efficiency of hulls / running gear and as a consequence the fuel consumption and maintenance requirements. When seawater is brought inside for cooling growth of marine organisms, barnacles and algae can restrict water flow, drastically reduce cooling efficiency and even damage your engine or ancillary equipment.

Protection with CleanAHull

CleanAHull utilises Ultrasonic Acoustic Energy to protect Hulls, Shafts, Rudders, Propellers, Waterjets, Stern Drives & more on the outside along with protection of Sea Chests, Tanks, Box Coolers, Pipe networks, Intakes & Valves.

Ultrasonication Explained (Acoustic Ultrasonic Energy)

In brief, the CleanAHull transducers are strategically installed in the vessel, running gear, sea-chests, box coolers, pipe networks, intakes, etc. They are driven with the CleanAHull Ultrasonic sound waves which produce pressure variations in the liquid (seawater) causing microscopic cavitation, these sound waves generate an alternating high pressure and low pressure cycle. During the pressure cycle billions of microscopic vacuum bubbles are created and collapsed 20,000 – 200,000 times per second. The effect of this is two fold, disruption and destruction of microscopic algae (sterilization) and microscopic scrubbing effects which can break down solids allowing a constant cleaning effect.
