Configurable polarity reversal

No scale build-up. Stérilor process optimising the life of the electrodes.

Auto-adaptability to water salinity

The appliance maintains constant production throughout the season despite the drop in salt levels caused by water top-ups. The life of the electrodes is optimised.

7 operating modes:

  • Normal: continuous production.
  • Boost: production at 120% for a maximum of 24 hours.
  • Timer: treatment time programming each time the filtration pump starts
  • 24/24: treatment time programmed over 24 h, split proportionally every hour
  • Delayed start-up (up to 120 h).
  • Automatic winterisation (optional temperature sensor required).
  • Standby.

Redox control option.

Automatic electrolyser production control by adding the ORP EVO Kit.

Slow Mode :

Automatic coupling of the treatment to the slatted cover, cover or shelter position. Adjustable output for operation with the slatted cover closed.

Shock chlorination:

Production is boosted to its maximum from 1 to 24 hours, with automatic return to the initial mode.

Proportional pH control +/- :

pH injection adjusted automatically depending on changes in the pH measurement.

No flow/no water safety:

Detection of lack of flow or lack of water in the electrolysis cell.

Smartphone control and management:

Local update and control using the “WelcomPool” mobile app designed for intuitive day-to-day use.

Nextpool Pilot compatibility:

Wireless integration with the Nextpool Pilot connected solution for automated pool management (filtration, lighting, heat pump, etc.) and remote control of treatment functions (production settings, alerts, etc.).
