Our Ultrasonic System uses digital ultrasonic technology which emits sound waves ranging from 19.08 to 41.66kHz in 14 bands with 200ns steps. When the control driver activates the ultrasonic transducers, which are attached to the inside of the hull, multiple bursts of ultrasonic energy is released simultaneously through these frequency ranges. This energy produces a pattern of alternating positive and negative pressures.
This alternating pattern creates microscopic bubbles during the periods of negative pressure and implodes them during the period of positive pressure i.e. cavitation. The implosions create a micro-jet action which not only provides the cleaning effect on the hulls surface below the water line, but also resonates the hull which destroys organisms such as algae and makes it difficult for other such organisms to attach.
By preventing algae growth on the hull, other marine crustaceans such as barnacles, mollusks, and limpets do not attach to the hull or running gear, as not only is their food chain non-existent, but the changing frequencies act to crustaceans as unwanted marine predators.
Although ultrasonic systems have been around for many years, they were analogue in nature and did not operate over the many frequencies outlined above. They were noisy and required relatively high power levels to operate (see our FAQ section).
