WHAT IS IT?
A new concept for improved water quality.
It generates chlorine from common salt already dissolved in the swimming pool’s water.
As such there is no need to handle chemical products, it simplifies maintenance.
It guarantees healthier and more enjoyable bathing.
- Inexpensive and easy to install in any type of swimming pool
- Totally eliminates the use of chlorine
- Operates with sea water
- Avoids the problems of itching skin and irritated eyes
- Helps protects tissues
- Favours tanning
- Minimum maintenance requirements
CLEARLY MORE COMFORTABLE
For your further comfort, all of the models are equipped with detachable touch screens, connected via a cable or through Wi-Fi, so you may control the water’s parameters without even leaving your home.
Over 15 different models that constantly maintain the water healthy, clean and crystal clear, with no work and no hassles.See Automation by vistaPOOL ⇒

The traditional water treatment method for swimming pools essentially consists of adding chlorine in any of its commercially available forms.
SALINE ELECTROLYSIS SYSTEMS bring a new concept in water treatment to your swimming pool, providing improved water quality, eliminating the need to handle chemical products and simplifying maintenance tasks, as it generates chlorine directly from the salt already dissolved in the water. The salt it requires to operate should be added to the pool at a concentration of 4 - 6 kg/m3 (5 - 6 times less than that of sea water). The system adds the salt to the water and produces chlorine (Cl2) at the anode of the electrolytic cell via the following electrolysis reaction:
2NaCl + 2H2O = 2NaOH + H2 + Cl2 (salt + water = sodium hydroxide + hydrogen + chlorine)
The chlorine dissolves in the water to form hypochlorous acid:
Cl2 + H2O = HOCl + HCl (chlorine + water = hypochlorous acid + hydrochloric acid)
Hypochlorous acid oxidizes bacteria present in the water. As can be appreciated below, it also generates another product, active oxygen (O2), which adds further disinfection capacity to the process by sterilizing the water:
2HOCl = 2HCl + O2 (hypochlorous acid = hydrochloric acid + oxygen)
Once the water is disinfected, the hydrochloric acid reacts with the sodium hydroxide in what is called a neutralization reaction, reverting back to salt and water. The hydrogen and oxygen atoms react to form water:
NaOH + HCl = NaCl + H2O (sodium hydroxide + hydrochloric acid = salt + water)
The system, therefore, is a closed process in which none of the products are consumed. Salt only needs to be added to the water once, when the pool is first filled. Afterwards, small amounts should occasionally be added to replenish the salt lost with the water when cleaning the filters.
Chlorine generated by the electrolysis process destroys organic matter and pathogens in the water, before finally transforming back into sodium chloride (common salt).
Which explains why the salt concentration remains practically constant.
