PYI introduces Soni8 ultrasonic anti-fouling protection


(LYNNWOOD, Wash.) — PYI Inc. has announced the newest product in the Sonihull ultrasonic antifouling product lineup, Soni8. Soni8 uses ultrasonic anti-fouling technology to prevent marine organisms from colonizing solid surfaces that are exposed to raw seawater. Soni8 is born from the commercial marine market’s demand for a cleaner, more cost-effective way to protect multiple areas and devices against marine biofouling.

With eight independent and programmable outputs, Soni8 can protect every part of a vessel or structure. With one panel and eight transducers, Soni8 can protect all critical equipment inside and outside the hull.

Soni8 will be available for purchase in February 2018.

Inside – Sea chests, tanks, keel coolers, box coolers, pipework, intakes, valves.

Outside – Hulls, structures, shafts, propellers, waterjets, stern drives, steering gear.

Fouling on the hull and propellers can increase fuel consumption by up to 30 percent and, in raw water pipes, fouling will block cooling systems and cause premature equipment failure.

Environmental legislation covering the use of poisonous metallic biocides in anti-fouling coatings is tightening and marine-based industries are looking for more effective means of preventing unwanted marine growth on their vessels and inside their equipment. Since 2006, NRG Marine has protected over 15,000 vessels with its Sonihull ultrasonic anti-fouling systems.

For decades, ultrasonic technology has been used in the food, brewing and hydroponic farming industries to prevent algal blooms and to keep water-handling equipment clean and free from blockages. By focusing the same technology into marine applications, Sonihull has become an effective anti-fouling solution.

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 and cost – No expensive anodes to replace, no special fittings, dry-docking or current isolation required. Can save up to 95 percent of capex when compared to lifetime costs of other antifouling solutions.

Microbial control – Suppresses diesel bug in stored fuel and keeps stored potable water fresher for longer.

Eight independent transducers – Soni8 effectively opens the market for large installations, where multiple surfaces and critical 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 80 meters away – Transducers are impedance matched, enabling cable lengths to be extended to 80 meters with no loss in performance. This makes Soni8 suitable for modular pre-fabricated constructions.

Fully programmable and integratable – Full RS232/RS422 and SCADA communication interface for wire/wireless remote control with critical patch fault monitoring.

Mobile app – Enables remote viewing, monitoring and control (requires WiFi/4G interface module)
