Our products include mounting systems, coupling systems & damper drive plates:

Sonihull

The Sonihull ultrasonic antifouling system by NRG Marine uses the latest digital electronics and ultrasonic transducer technology. This system works by producing bursts of ultrasonic energy in multiple frequencies, the energy creates a pattern of alternating positive and negative pressure. Microscopic bubbles are created from the negative pressure, while the positive pressure implodes them forming vapor cavities known as cavitation. The result of the implosion is a micro jet action that creates a cleaning effect on the hulls surface below the waterline. It also resonates and destroys single cell organisms such as algae. Removing the initial link in the food chain prevents barnacles and other marine life to feed on the algae.


There are 3 Sonihull Systems, the Sonihull Mono, the Sonihull Duo and the Sonihull8:


PIPE ADAPTER

Fouling in pipe work can be a major problem. It doesn't take long before fouling can start to restrict the flow of water, which can lead to engines and generators being destroyed as a result of over heating and water pumps wearing out due to the sharp increase in pressure.


Read more about Pipe Adapter.


BOX COOLER

Box Coolers are essential for keeping your engines and auxiliary systems working properly, marine bio-fouling on box coolers reduces water contact and cooling performance drops. This can accelerate engine wear and can lead to overheating and equipment failure. Traditional solutions require complicated installation and extensive maintenance.


Read more about Box Cooler Protection.


PROP SHAFT & PROPELLER PROTECTION

Prop Shafts & Propellers are one of the most critical elements of your vessel performance and fuel consumption. Controlling Fouling on the prop shaft and propeller surfaces can reduce your fuel bills by up to 40%, extend your essential maintenance intervals and remove the need for expensive downtime.


Read more about Prop Shaft & Propeller Protection.


SEA CHEST PROTECTION

Sea Chests are an important component in the maintenance and operation of your cooling system. Sea chests provide a perfect habitat for marine organisms and if left un-protected will quickly become choked with algae, weeds and molluscs. Traditional solutions require complicated installation and extensive maintenance.
