The Ultrasonic Anti-Fouling system of Sonihull is a preventive system that consists of a control box and one or more transducers. The transducers are glued on the inside of the ship (hull) with a 2-component industrial epoxy glue. They give an ultrasonic signal and use the hull as a sound box. This high-frequency signal will kill the single-cell bacteria (algae) and in this way prevents further growth on the ship. These single-cell bacteria are in fact the source of food for other organisms in the water.

For correct installation and warranty, it is advisable to have the system installed by Lamers System Care for the first time. The gluing of the rings of the transducers and the positioning of the transducers in particular require professional attention and experience.

The system uses 3.6 watts per transducer. It is possible on both 110-240 VAC and 12-24 VDC. If both are connected, the system itself automatically chooses the VAC shore power and when it fails, the system automatically goes to the VDC. If the battery voltage becomes too low, the system automatically switches off to save the battery.

The system cannot be felt when it is switched on. Ultrasonic is not perceptible to human hearing. What can be heard is the “clicking” of the Ultrasonic transducer, but this is negligible.

The system has no effect on underwater life. The system has too little power to guide the ultrasonic waves through the water. 3.6 watts per transducer is suitable for destroying single-cell bacteria, but too low to affect other organisms.

The system is applicable to steel, aluminium and plastic (polyester), as long as it is a rigid material that can transport sound and doesn’t absorb the sound.

No, the ship does not have to be in dry dock. We can install while the ship is in the water.

The Ultrasonic system is a preventive system, which prevents fouling on a clean ship. The ship does not have to be clean for the installation itself. However, for the system to work properly, you must start with a clean ship for the best results. The Ultrasonic system does not remove existing fouling, it can only delay the process.
