Description
Evolution: 7 SEL EVO+ SYSTEM 2021
The System 7 SEL EVO+ electrolyzer has undergone technological advancements:
- Power supply suitable for the bipolar electrode (120 watts)
- New device interface for even more tailored settings
- EVO = 30 to 180% and forced operation 200%
- EVO+ = 15 to 100% and forced operation 120%
- Setting up the electrode model to limit the current intensity and extend the electrode life.
- More intuitive operating ranges
- Simple and intuitive adjustment of chlorine production over a range between 15% and 100%.
- "Normal" (economy) range up to 70% for regular use
- "Performance" range of 75% to 100% for occasional use (setting to be used in case of high traffic and high water temperature)
- The EVO+ product incorporates an additional chlorine reserve of approximately 20% compared to the EVO range.
- "Boost or forced" mode: 120% for up to 24 hours
- Setting the water hardness to adjust the polarity reversal time
- Alarms: 3 levels of electrode status detection
For simple and effective pool treatment in all circumstances,very easy installation and adaptable to all filtration systems.

Easy to use:
- Simplified reading thanks to a display that provides at a glance clear and precise information on the percentage of production, diagnostics and the functions "forced operation", "polarity reversal" and "Slow Mode".
- Self-cleaning electrodes with automatic, configurable polarity reversal. Prevents electrode scaling.
- Self-adapting to water salinity: The device maintains constant production by adapting to salinity variations throughout the season (losses, filter backwashing, water top-ups). Electrode lifespan is optimized.
Self-cleaning electrodes
- By automatic reversal of configurable polarity.
- Prevents scaling of the electrodes.
Self-adaptation to water salinity
- The device maintains consistent production by adapting to salinity variations throughout the season (losses, filter backwashing, water top-ups). Electrode lifespan is optimized.
Shock chlorination
- This function allows for superchlorination for 24 hours after periods of high traffic.
Clear visualization of diagnoses
- facilitating checks, maintenance and telephone support.
Integrated and configurable Slow Mode system
- For pools equipped with a cover, shutter, or enclosure. It allows for the automatic reduction of production to a configurable value when the pool is covered.
Recommended combinations for consistent water quality thanks to the combination of controlled salt electrolysis and pH regulation.
- Stér-pH U: system ensuring pH regulation.
- Steredox U: a salt electrolysis controlled and regulated by Redox measurement.

Composition
- Control box.
- Electrolysis cell with its salt electrolyte.
- Complete installation kit.
- Salinity test.
Features
- Configurable polarity reversal (New): No scaling. Stelor process optimizing electrode lifespan.
- Self-adapting to water salinity: The device maintains constant production and therefore adapts to water losses or top-ups throughout the season. The lifespan of the electrodes is optimized.
- Slow Mode: Automatic control of the treatment based on the position of the shutter, cover or shelter (1). Production can be configured in open and closed mode to suit all cases.
- Shock chlorination: This function allows for superchlorination; production is boosted to its maximum for 24 hours with automatic return to the initial settings.
- Water shortage safety: The system shuts down when it detects the absence of water in the electrolysis tank.
- Diagnostics: To inform the user when necessary, a diagnostic code automatically appears on the device's screen. Each code refers to an explanation in a table included in the user manual, allowing for understanding and troubleshooting, even remotely.
(1) If equipped with limit switches (otherwise it is possible to install a household-type switch simulating the limit switch).
What specifically changes on electrolysis vessels
- A transparent vase allows visualization of chlorine production.
- Integrated deflector for even production. Water flow distributed across the entire surface of the plates. • Nut mounting for easy installation.
- Offset 50 and 63 mm connection for simplified installation.
- Electrode alignment guide, ensuring installation in the correct orientation and alignment with the water flow.
- Optional modules available: accessory holder allowing easy adaptation of injectors, pH probe, redox probe, flow detector, analysis chamber connection, pool-ground.
New electrodes for unparalleled efficiency
- Bipolar electrodes
- A wider range adapted to the volumes of the pools
- Salt content of 4 grams per liter
- Integrated alignment guide for correct electrode positioning
- New 25 m3 electrode specially designed for small ponds
- Corrosion-protected connectors for outdoor installation
