Titanium Electrode for Salt Chlorinator: Why MMO Coated Anodes Outlast Others in Swimming Pool Electrolysis If you are sourcing electrodes for a salt water chlorination system, you face a critical decision: which anode material will survive the aggressive salt environment long enough to keep maintenance costs predictable — and which will leave you replacing components every season? The answer separates profitable pool equipment businesses from those bleeding money on reactive maintenance. The Salt Chlorinator Environment: Why It Destroys Most Electrodes A salt chlorinator works by electrolyzing dissolved sodium chloride (NaCl) to generate free chlorine, keeping pools sanitized without manual chemical dosing.
