21 g/h cell electrode for CTX Go Salt and GRE chlorinators

The replacement electrode/cell we offer is the direct solution for restoring your chlorinator's performance when the original cell has lost effectiveness due to wear. With use, the plates gradually become less active and chlorine production decreases, resulting in cloudy water, greater chemical instability, and increased consumption of balancing products. By replacing the cell with this replacement part, the equipment returns to its rated operating range, making it much easier to keep the water clear and disinfected every day.

This replacement part is designed for residential installations seeking stable and predictable chlorination. Its 7-plate design supports a production rate of 21 g/h (depending on the chlorinator), while its construction with materials resistant to saltwater helps extend the service life of the assembly. If you notice a drop in production, low-cell warnings, or disinfectant levels fluctuating for no apparent reason despite having adjusted the pH, replacing the electrode is usually the most effective way to restore the balance.

Installation is simple and can be carried out by the user: turn off the power and water flow, loosen the connections (a 13 mm open-ended wrench is usually sufficient), remove the old cell, and install the new one in the same direction. Take the opportunity to check the condition of the gaskets and cell housing, remove any possible deposits, and purge the air before starting up. After replacing it, follow the chlorinator manufacturer's instructions (salinity, flow rate, and filtration times) to ensure optimal operation.

Below you will find the compatibility table for the equipment most commonly used with this cell. If your model does not appear, contact us with the exact reference of your chlorinator so we can identify the correct replacement.
