ULTRASONIC ANTIFOULING SYSTEM

SONIHUU- ULTRASONIC ANTIFOULING SYSTEM THE PROBLEM... For hundreds of years mariners have been plagued with the same old problem of marine growth on the hull, power train and steering gear for their yachts. With this comes: • Reduced speed due to extra drag. • Increased fuel consumption, estimated at as much as 20%. • Propeller cavitation (which in turn causes extensive damage to propellers). • Expensive annual haul outs and repainting costs. THE SOLUTION... Sonihull is a cost effective antifouling product that works alongside a conventional antifouling paint with additional benefits. In...

ULTRASONIC ANTIFOULING SYSTEM Sonihull systems produce multiple bursts of ultrasonic energy in a range of targeted ultrasonic pulse frequencies. This produces a pattern of alternating positive and negative pressure, whereby the microscopic bubbles that are created during the negative pressure are imploded when positive pressure is applied. This implosion has a cleansing effect that destroys algae, the first link of the food chain, making the surface less attractive to other marine life that feed on the algae. This microscopic movement of water also prevents barnacle and mussel larvae from...

ULTRASONIC ANTIFOULING SYSTEM SONIHULL SYSTEMS The Sonihull Ultrasonic Antifouling System offers superior performance and reliability with a combination of features not offered by any competitor. Sonihull Mono 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...

WHICH SONIHULL SYSTEM? The Sonihull System is available in a single transducer “Mono”, or a two transducer “Duo”. Which Sonihull System, or the number of transducers needed is determined by the waterline length of the boat. This chart shows what combination of Mono, and Duo systems are needed to protect you boat. Transducers are placed near the vessel centerline and about twelve inches or more away from structures like primary bulkheads. As the beam of a boat approaches 20 feet the transducers will need to be positioned further outboard while reducing the fore & aft separation. A distance...

ULTRASONIC ANTIFOULING SYSTEM STERN DRIVE AND SAILDRIVE ADAPTOR Stern drives have always been problematic in terms of fouling. Due to the many different metals they are composed of, their moving parts and soft bellows, conventional copper impregnated antifouling paints are not an option. Sonihull coupled with the Stern Drive Adaptor offers great protection to this most important part of the boat that is prone to fouling. Results show an impressive average of 80% reduction in fouling. This device enables a Sonihull transducer to be simply screwed in, so that ultrasonic signals can be...

SONISHAFT Protection For Prop Shafts & Propellers The worlds first ultrasonic antifouling solution for prop shaft driven vessels. Sonishaft used in conjunction with the standard Sonihull transducer, clamps directly into the prop shaft, suppressing barnacle and bio-growth on the prop-shaft, propeller and anodes. Typically you would expect to see a reduction in growth by about 80% or more. Plus the additional benefits of maintaining performance, smoother ride and reduced wear and tear. All this while saving about 20% on your fuel bills! \f 20% saving on fuel consumption Good...

ULTRASONIC ANTIFOULING SYSTEM PROTECT YOUR SEA CHEST! Proven around the world on commercial, military and private vessels as a most valuable addition to the protection of inlets and pipework. Protection against growth and scaling, maximizing flow for intakes, filters, pipework, valves and heat exchangers. With no expensive anodes to replace, no corrosion and completely safe for use on both steel and aluminium vessels. The Sonihull systems have proven themselves as the most credible antifouling alternative to suppressed current/cathodic protection systems. This protection has not only been...

Easy Installation No Through Hulls! • Transducers are simply bonded to the inside of the hulls outer skin. • For vessels up to 30’ transducers should be installed in the rear 3rd of the yacht. • For vessels up to 50’ transducers should be installed 1/3 and 2/3 along the length of the yacht hull. • For larger vessels, the Sonihull is a modular solution, please contact PYI to discuss your requirements. Mounting The Control Box Find a suitable dry location above the waterline, with suitable access to either mains or battery power. Remove the lid to expose mounting holes for the control box....
