Sonihull 8 Ultrasonic Anti-Fouling System


QAR 0.00

The Sonihull8 is the latest addition to NRG Marine’s Sonihull range of ultrasonic anti-fouling technology. Sonihull’s fit-and-forget systems prevent marine organisms from colonizing solid surfaces that are exposed to raw seawater.

With eight independent and programmable outputs, Sonihull8 can protect every part of your vessel or structure from marine fouling with no through hulls. Unlike biocidal coatings and impressed-current systems, Sonihull8 is low cost and low maintenance, with zero poisonous environmental impacts. With one panel and eight transducers, Sonihull8 has all of your equipment covered.

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 alternating positive and negative pressure on the surface of the material. Microscopic bubbles are created during the negative cycle and are imploded during the positive cycle. This microscopic agitation has a cleansing effect which destroys surface 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.

  • Each transducer is powered by a dedicated signal generator, offering a continual signal to all transducers.
  • Transducers and their cable connections are rated for submerged operations.
  • Transducers have no exposed metal.
  • AC/DC power option defaulting to AC.
  • Automatic shut off in Low Voltage DC power situation to protect batteries.
  • Remote system status monitor.
  • Manufactured “In House” for the best possible quality control.
  • Virtually undetectable to the human ear with no need for a “sleep switch”.

  • Modular design (configurable as 4, 6 or 8 transducer outputs)
  • Each transducer channel is fully monitored for fault condition
  • Power supply protection supports overload/underload monitoring for input and operating voltages
    Networking & Programming

  • Programmable timer enables individual/group/all control
  • RS232 interface supports remote monitoring and control
  • Networkable up to 32 x Sonihull8 panels (possible total network size 256) for centralized monitoring and control of large installations
  • Fully compatible SCADA interface for vessel management systems
  • Mobile app enabling remote viewing, monitoring and control (requires WiFi/4G interface module)
  • Key Features

    Zero Environmental Impact
    No poisonous environmental impact from biocides or metallic compounds. Zero interference with SONAR arrays or black box recovery equipment.
    Low Maintenance
    No expensive anodes to replace, no specialist fittings, dry docking or current isolation required.
    Microbial Control
    Suppresses Diesel bug in stored fuel and keeps potable water fresher for longer.
    Eight Independent Transducers
    Sonihull8 effectively opens the market for large installations, where multiple surfaces and equipment can now be protected by one unit.
    Intelligent Multi-Material Commissioning
    Operators can select different resonance algorithms for each ultrasonic transducer to suit the different materials or structures being protected.
    Networks With Up To 32 Units
    A potential network of 256 independently controlled and centrally managed transducers, ideal for large installations or multiple areas of protection.
    Can Connect Up To 80m Away
    Transducers are impedance matched, enabling cable lengths to be extended to 80 meters with no loss in performance. This makes Sonihull8 suitable for modular pre-fabricated constructions.
    Fully Programmable & Integratable
    Full RS232 / RS422 & SCADA communication interface for wired/wireless remote control with critical path fault monitoring.
