Stelor DUO EVO+ Salt Electrolyzer: Intelligent Pool Treatment

Stelor Duo EVO+ Salt Electrolyzer

Salt electrolysis is a simple, natural, and environmentally friendly water treatment solution. This innovative process provides clear, healthy, and pleasant-tasting water without the use of traditional chemicals, thus avoiding eye irritation, unpleasant odors, and hazardous handling.

Natural and efficient operation

The electrolyzer electrode temporarily transforms a component of the salt into a powerful disinfectant. This disinfectant effectively eliminates bacteria and algae, then reverts back to salt before being reused in the cycle. This system thus ensures continuous disinfection while minimizing salt consumption.

Strengths

  • Complete absence of chemicals
  • Simple and hassle-free maintenance

Evolution: Stérilor DUO EVO+ 2021

  • The Stérilor DUO Salt / pH 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 

Two functions for complete treatment. Intelligent, it maintains water balance with salt electrolysis and pH regulation.


The importance of pH regulation

The acidity (pH) of pool water is a parameter that affects the effectiveness of water treatment and the comfort of swimmers. The ideal pH is between 6.9 and 7.3. STERILOR Duo continuously analyzes the pool's pH and corrects it as needed.

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.

  • 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.
  • pH measuring probe ref KAQ0699D
  • Calibration kit for the pH probe.
  • pH probe mounting kit.
  • All the necessary fittings for assembly.
  • Salinity test.

Features

  • Polarity reversal: Configurable. No limescale buildup. 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**. 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.
  • pH regulation +/-: Selection of the regulation mode without opening the box. Reading of the value +/- 0.1 pH.
  • Proportional regulation: The injection time produced is calculated based on the evolution of the observed measurement.
  • Product shortage detector: When the pH setpoint is not reached within a predefined time, the system goes into "safety" standby mode.
  • 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.

** If equipped with limit switches (otherwise it is possible to install a household-type switch simulating the limit switch).
