EMCS Industries Ltd. is the original inventor of the Marelco System (trade name is Cathelco in Canada). This is an electrolytic protection system developed and patented in 1961 in Canada and the United States by Electrolytic Marine Corrosion Services Limited of Victoria, British Columbia. The original concept was the use of impressed current and aluminum sacrificial anodes to control corrosion of seawater piping systems. The system was found to be effective against scale formation as well. Development and improvement of the original system over the years produced a combined anti-corrosion/anti-fouling system.

Their product Marelco, is a patented impressed current system employing specially alloyed anodes. Marelco eliminates marine growth infestation and reduces corrosion in saltwater cooling systems. Marelco provides continuous protection, demands negligible maintenance, and is easily applied to new or existing installations.
