Sonihull8 Antifouling System

£7,080.00

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 colonising 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. Unlike biocidal coatings and impressed-current systems, Sonihull8 is low cost and low maintenance, with zero poisonous environmental legacy. With one panel and eight transducers, Sonihull8 has all of your equipment covered.

Description

Sonihull8 Antifouling System

Sonihull antifouling 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.

Key Features

ZERO ENVIRONMENTAL IMPACT
No poisonous environmental legacy 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, drydocking or current isolation required.

MICROBIAL CONTROL
Suppresses Diesel bug in stored fuel and keeps potable water fresher for longer.

8 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 metres 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.
