Astralpool Smart Next 21 g/h electrode

The AstralPool 70312 electrode is the specific replacement cell for Smart Next 21 chlorinators and their versions with regulation, designed to restore chlorine production when the original cell has degraded through use. This reference corresponds to the 21 g/h model in the Smart Next family, AstralPool’s compact salt chlorination range with standard, pH and pH/ORP versions, production modes (Normal, Boost 24h and Biopool), and display of parameters such as salinity and temperature in its interface. By replacing the cell with the 70312, you can resume operation within the nominal values specified for this range, with stable disinfection and less need for chemical adjustments.

The replacement is designed for quick and direct installation, without modifying the existing hydraulics. Smart Next/E-Next cells use activated titanium electrodes and self-cleaning through polarity reversal, reducing scale buildup and helping to keep the active surface in good condition for longer. Before replacing it, switch off the power and water flow, check the seals and the cell housing seat, remove any deposits, and, after installation, purge the air and verify that the operating salinity is within the range recommended for the Smart Next series (min. 5 g/L; recommended 5–6 g/L; max. 12 g/L).
