Ruthenium-Iridium Coated Titanium Anodes for Swimming Pool Salt Chlorinators – Core Components of Pool Disinfection Equipment

Many swimming pool equipment manufacturers and pool operators struggle with the durability of electrode accessories when matching salt chlorination systems. Ordinary stainless steel and graphite electrodes on the market corrode and crumble quickly after short-term use, resulting in steadily declining chlorine output and impurity precipitation that clouds pool water, leading to high costs for frequent replacement and maintenance. Today, ruthenium-iridium coated titanium anodes have become the standard upgrade for most disinfection equipment.

Our titanium anodes dedicated to swimming pools are all made of high-purity TA2 titanium substrates. Multiple layers of ruthenium-iridium catalytic coating are sintered on the surface via high-temperature thermal decomposition processes, specially engineered for low-salinity salt water electrolysis in swimming pools. They reliably adapt to the intermittent start-stop operation of both small residential pools and commercial pools in hotels and homestays. Finished products come in three styles: plate type, expanded mesh type and integrated tubular assemblies. Mesh anodes feature larger contact areas with salt water for consistent, even chlorine production; tubular anodes fit directly into equipment electrolytic cylinders, ideal for OEM supporting by equipment manufacturers. Standard terminals are pre-installed at the factory

for direct replacement and installation without extra processing or modification.

When immersed in salt-containing pool water long-term, the titanium substrate naturally forms a passivation protective film to resist rust and deformation. Paired with firmly bonded ruthenium-iridium coating, the anodes operate stably for 3 to 6 years without frequent replacement. Electrolysis only breaks down salt in water to generate hypochlorous acid, with no heavy metal leaching that irritates swimmers' skin, and the water cleanliness meets international swimming pool water quality standards. Routine maintenance is simple: in areas with hard water, soak the anodes in weak acid regularly to remove surface scale and restore full chlorine output performance.

Many overseas distributors of swimming pool equipment place bulk repeat orders for these standardized anodes. Each unit is individually wrapped with foam protection during packaging to prevent coating scratches and damage during long-distance sea and land transportation. Customization is available based on customers' equipment dimensions and wiring specifications, compatible with most imported and domestic salt chlorination disinfection units.
