Control Biofouling and lower Fuel Consumption

The LG Sonic devices emit specific ultrasonic parameters in order to prevent biofouling in hulls en sea chests.

Biofilm formation starts by bacteria attaching to a surface. The ultrasonic sound waves of LG Sonic create resonance around the solid surfaces within the water, thereby preventing bacteria to adhere to a surface. EPS, present in an existing biofilm, is directly targeted, degrading the biofilm. When bacteria, algae and biofilm are reduced, as a result, the dosage of biocide and/or antifouling measures can also be reduced.

Benefits of biofouling control in cooling basins

Effective biofilm control

Reduces fouling by up to 80% on the hull and prevents the growth of new biofilm.

Decrease dry-docking intervals

Because of the continual protection the hull remains clean with no need for dry-docking.

Safe for the marine ecosystem

Ultrasound effectively prevents biofouling without the use of harmful chemicals and without harming the marine ecosystem.


Improves fuel economy

By preventing the biofilm from growing a remarkable reduction in fuel of consumption is achieved.


Easy installation

Due to our marine grade design mounting footprint technology it is very easy to install the system.


Prevent damage to the anticorrosion layer

Avoid damage to industrial systems such as to filters. The anticorrosion layers will be preserved.
