Ultrasonic anti-fouling system by NRG Marine.

FIT & FORGET BIO-FOULING PROTECTION

Wherever your vessel is exposed to raw seawater you need to protect against biofouling. On the outside, the build-up of algae, weeds, barnacles and other unwanted marine life will slow you down and increase your fuel bill. On the inside, marine organisms can restrict cooling water and even damage your engine. That is where our ultrsonic antifouloing system comes in to action. 

Sonihull Ultrasonic
Anti-fouling System

NRG Marine uses the latest digital electronics and ultrasonic transducer technology. This system works by producing bursts of ultrasonic energy in multiple frequencies, the energy creates a pattern of alternating positive and negative pressure. Microscopic bubbles are created from the negative pressure, while the positive pressure implodes them forming vapor cavities known as cavitation. The result of the implosion is a micro jet action that creates a cleaning effect on the hulls surface below the waterline. It also resonates and destroys single cell organisms such as algae. Disrupting this first link in the food chain keeps the surface clean and makes it a much less inviting habitat for larger organisms that feed on the algae. The microscopic movement of water also prevents barnacle and mussel larvae from embedding on the surface.
