NRG Solutions is a high tech company specialising in the design and development of environmentally friendly electronic solutions for specialist and environmentally aware subjects, such as Building Automation and Controls and Life Safety Systems. NRG Marine is the latest division to be added to the NRG Solutions group.

NRG Marine develop and produce:

  • NRG Sonihull Ultrasonic Antifouling Systems for yachts of all sizes.
  • PFE - Portable Fire Extinguisher


For hundreds of years mariners have been plagued with the same old problem of marine growth on the hull, power train and steerage gear of their yachts. with this come the problems of.

  • Reduce speed, due to extra drag
  • Increased fuel consumption, estimated at as much as 20%
  • Propeller cavitation (which in turn cause extensive damage to propellers)
  • Expensive annual haul out and repainting

Eco friendly Electronic Antifoul solution.

The NRG Marine Hull protection system for boats utilizes the latest digital electronics and Ultrasonics transducer technology by producing multiple burst of ultra sonic energy simultaneously in a multiple range of frequencies. This energy produces a pattern of alternating positive and negative pressure.

The alternating pattern creates microscopic bubbles during periods of pressure and implodes them during priods of positive pressure in a phenomenon known as "cavitation." The implosion creates a micro-jet action that not only provides the cleaning effect on the hulls surface below the water line, it also resonates and destroys single cell organisms such as algae. The removal of the initial link in the food chain inhibits the growth barnaches and other marine life that feed on the algae.

The Sonihull System is an environmentally friendly solution for marine antifouling in general, suitable for all types of hull materials excluding wood.

The Benefits of the Sonihull System

A clean hull can save you about 20% of your fuel Bills. It is common knowledge that fouling on the boat's hull, will lead to increased resistance, which basically means you are going to burn more fuel for every knot you make. The outcome is compromised efficiency and a poorer mpg figures that with a clean hull which is usually achieved with antifouling paint.

Fouling is usually suppressed through the use of antifouling paint. Tests show that NRG Ultrasonic Antifouling Systems pose no danger to marine life, whereas antifouling paint is known to be damaging to the environment.
