Sonihull ultrasonic antifouling systems

  • Zero poisonous environmental legacy

    Unlike biocidal coatings and impressed-current systems, Sonihull is low cost, low maintenance with zero poisonous environmental legacy.

  • Protects inside-and-outside

    From hulls, shafts, propellers and waterjets, to sea-chests, tanks, keel-coolers, box-coolers, pipework, intakes and valves.

  • Complete range of solutions

    Sonihull is a complete range of fit-and-forget ultrasonic antifouling solutions for any solid surface that is exposed to raw seawater.

How it works

Sonihull systems produce multiple bursts of ultrasonic energy in a range of targeted pulse frequencies.

These pulses are transmitted through the material that the transducer is attached to.

The ultrasound produces a pattern of increasing and decreasing pressure on the surface of the material.

Increasing and decreasing pressure

The ultrasound produces a pattern of increasing and decreasing pressure on the surface of the material. In a process called non-inertial cavitation, microscopic bubbles are created during the reduced pressure cycle and are imploded as the pressure increases. The microscopic agitation has a cleansing effect which destroys surface algae.

The benefits

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.

Key Features of Sonihull Ultrasonic Antifouling

Environmentally Friendly

Effective bio-fouling without the poisonous environmental legacy of biocides or microplastics.

Easy Installation

No drydocking, no through-hull fittings, no expensive Impressed Current Antifouling copper anodes to replace.

Less Downtime

No cleaning hard-to-reach areas, extended maintenance intervals, less downtime and reduced running costs.

No Disturbance

Inaudible to humans and marine life with no interference to sonar and electronic equipment.

Lower Fuel Consumption

Clean hull, propellers and rudders can reduce fuel consumption by up to 30%.

Microbial Control

Ideal for bulk storage. Sonihull suppresses Diesel bug and keeps potable water fresher for longer.

Low Power Consumption

At only 3.6 Watt-hours per transducer, Sonihull is ideal for onboard, standby or remote power.

Lower Operating Costs

Can save up to 95% of capital and MRO costs when compared to impressed-current antifouling systems.

Easy System Integration

Compatible with RS232 / RS422 and Modbus communication interface for remote control with critical path fault monitoring.
