Salt electrolyser

Stérilor Duo EVO

STÉRILOR Duo is smart and maintains the water in balance using salt electrolysis and pH regulation.

Full treatment, total comfort.

Two functions for a full treatment.

STÉRILOR Duo stabilises the pH level while limiting the injection of corrector into the pool water, offering very simple disinfection.

Product benefits

  • A luminous LCD colour screen which displays all the parameters at a glance.
  • Instant access to all configuration functions using the buttons on the unit.
  • 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). The lifetime of electrodes is optimised.
  • 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.
  • Integration of a flow rate sensor which stops electrolysis in case the flow rate is zero or too weak.
    Auto-acquit system.

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.

Flow rate sensor:

Detects when the water flow on the electrolysis cell is at zero or very low.
Auto-acquit system.

Proportional regulation:

Product injection time is calculated according to the observed change in the measurement.

Low product level sensor:

If the pH set point is not reached in a specified time, the system puts itself into Standby safety mode.

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.

Chlorine coupling (optional):

The chlorinator is controlled by the Stéredox or Stérpro unit = controlled treatment and constant water quality.
Coupling is done without cutting the appliance power supply; production drops to 0% and a diagnostic message appears.

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.

pH +/- regulation:

Choose the regulation mode without opening the unit.
Value readings to +/- 0.1 pH.
