ElectroStrainer® is the world’s only all-in-one smart biofouling-prevention system with integrated sea strainer for boats. ElectroStrainer replaces your existing sea strainer and prevents marine growth through all seawater lines by generating a precise, low level of chlorine directly inside its strainer basket. The award-winning ElectroStrainer combines four components: a smart control and flow-monitoring system, an innovative biofouling prevention device, a hydrodynamic sea strainer, and a remote display (optional on ElectroStrainer Sport models).
ElectroSea® offers two options for all-in-one marine growth prevention – ElectroStrainer® Pro and ElectroStrainer® Sport.
ElectroStrainer Pro is our premium marine growth prevention system. ElectroStrainer Pro is available in four strainer inlet/outlet sizes and is engineered for exceptional performance. Backed by professional installation and a 2-year parts-and-labor warranty, ElectroStrainer Pro is the ideal choice for those seeking the ultimate in quality and reliability. ElectroStrainer Pro is available both for new build and refit installations.

ElectroStrainer creates an environment where marine growth simply can’t live. As seawater enters the boat, the patented electrochlorination system generates a safe and effective low level of chlorine, about the same amount as found in tap drinking water, in its strainer basket. No chemical additives or acids required. Treated seawater flows through the entire cooling system. Your lines remain free of marine growth, strainers stay clean longer, and you’ll never have to acid descale again. Period!
ElectroStrainer is available for new build or refit boats and fits center consoles, cruisers, sportfishers, sailboats, and superyachts. Installation is straightforward and can be completed while the boat is in the water. The ElectroStrainer Canister is plumbed in place of a traditional sea strainer and the integrated Control Head is connected to 12- or 24-VDC power.
