Simple and efficient salt electrolysis

Système 7 Sel EVO ensures hygienic water while avoiding chemical treatments and their drawbacks (red eyes, unpleasant smells, handling and storing chemicals, etc.).

The electrolyser unit transmits a low voltage electrical current to a cell (electrode) which will temporarily convert an element of the salt into a powerful disinfectant.

Product benefits

  • Simpler readout with clear and precise display on the percentage of production, diagnostics and “override”, “polarity reversal” and “Slow Mode” functions.
  • Very easy to install and adaptable to all filtration systems.
  • Automatically adapts to water salinity: the system maintains constant production while adapting to variations in salinity throughout the seasons (water loss, filter washing, top-ups)
  • Built-in and configurable Slow Mode system for pools fitted with a slatted cover, standard cover or a shelter.
    It automatically lowers production to a configurable setting when the pool is covered.
  • Shock Chlorination: function enables a boost on the chlorination level for 24 hours after high attendance.

Configurable polarity reversal:

No limescale deposits.
Stérilor process to optimise electrode lifetimes.

Automatic adaptability to water salinity:

The system maintains constant production and adapts to water losses or top-ups throughout the season.
The lifetime of electrodes is optimised.

Slow Mode:

The treatment is automatically coupled to the position of the cover or shelter.
Configurable production in open and closed mode to meet the needs of all cases.

Chlorination boost:

This function boosts the chlorination process to maximum for 24 hours and automatically returns to its initial setting afterwards.

Water level safety:

The system activates safety mode if it detects that there is no water in the electrolysis vessel.


To inform the user whenever necessary, a diagnostic code automatically appears on the appliance screen.
Each code refers to an explanation in a table incorporated in the user manual. The explanations enable users and technicians to understand and resolve issues, even remotely.
