EVO+ 2021 salt chlorinator: natural and efficient pool treatment

Evolution: EVO+ 2021 Salt Electrolyzer

The 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%
• 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

For simple and effective pool treatment in all circumstances

• An environmentally friendly treatment, for clear and healthy water by avoiding chemical treatments and their inconveniences (red eyes, bad smells, dangerous handling…).
• Setting up the electrode model to limit the current intensity and extend the electrode life.
• More intuitive operating ranges
• Setting the water hardness to adjust the polarity reversal time
• Alarms: 3 levels of electrode status detection

The simple and natural treatment

Like all devices in the range, Stérilor Sel benefits from high-quality design and assembly, with uncompromising care taken in the choice of materials and components, for lasting effectiveness.

Principle of salt electrolysis

The electrode temporarily converts a component of the salt into a powerful disinfectant. Minimal salt consumption, no water changes required—natural well-being!
Choosing salt electrolysis means choosing clear, healthy water while avoiding chemical treatments and their drawbacks (red eyes, unpleasant odors, dangerous handling, etc.).

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-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.
  

Integration of a flow sensor

• It stops electrolysis in case of absence or insufficient water flow. Self-resetting system.
  

Shock chlorination

• This function allows for superchlorination for 24 hours after periods of high traffic.
  

Maintaining a constant water quality

• With the electrolyzer controlled by Steredox or Sterpro. When the temperature is below 15°C, production drops to 0% and a diagnostic message appears.
  

Clear visualization of diagnostics 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 associations

Consistent water quality thanks to the combination of controlled salt electrolysis and pH regulation.

• Stér-pH U: system ensuring pH regulation.
• Steredox: a salt electrolysis controlled and regulated by Redox measurement.
• Stérpro: a salt electrolysis system controlled and regulated by an amperometric measurement of the free chlorine level. When the temperature is below 15°C, production drops to 0% and a diagnostic message appears

Composition

• Control box.
• Electrolysis cell with its salt electrode.
• 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.
• Flow sensor: Detects the absence or lack of water flow to the electrolysis cell. Self-acknowledging system.
• Water shortage safety: The system shuts down when it detects the absence of water in the electrolysis tank.
• Chlorine control: Electrolyzer control via Steredox or Sterpro = controlled treatment and maintenance of constant water quality. The control is achieved without interrupting the power supply to the unit; production drops to 0% and a diagnostic message appears.
• 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.
