The operation of a Salt Chlorinator<\/strong> is based on a simple principle: Salt Electrolysis. From the salt dissolved in the water, the equipment is able to generate chlorine automatically, keeping the pool always disinfected without the need to constantly add chemicals.<\/p>\n\n\n\n

It is a product that has become one of the most demanded options for pool water treatment<\/strong>. The reason is that, compared to other traditional methods, it offers a more economical, comfortable, safe, skin-, eye- and environment-friendly experience.<\/p>\n\n

What is a salt chlorinator<\/h2>\n\n

A Salt Chlorinator<\/a> is a device that is part of the Pool filtration system<\/strong>. Its mission is to transform common salt, previously dissolved in water, into chlorine through a process of electrolysis.<\/p>\n\n

The difference with traditional chlorine is clear: instead of adding tablets or liquids manually, the chlorinator continuously generates the<\/strong> necessary disinfectant<\/strong> to keep the water in perfect condition. This translates into cleaner water, with fewer chemicals and much more pleasant for bathers.<\/p>\n\n

How a Salt Chlorinator works, the Salt Electrolysis Principle<\/h2>\n\n

The operation of a Salt Chlorinator is simple and automatic. Once the salt is dissolved in the pool water, the chlorinator passes it through the blades located in the cell of the equipment. Electrolysis takes place there: the salt (sodium chloride) is transformed into free chlorine<\/strong>, which acts as a natural disinfectant.<\/p>\n

\n
\"How<\/figure>\n<\/div>\n

This salt chlorination<\/a> process is cyclic. The chlorine, once it has fulfilled its function, is converted back to salt, which allows constant production to be maintained without the need to add additional chemicals.<\/p>\n\n

Main components of a Salt Chlorinator operation<\/h3>\n\n

A modern salt chlorinator consists of three key elements:<\/p>\n\n
