What is a Salt Water Chlorinator

A Salt Water Chlorinator simply turns Salt into Chlorine. This is a chemical reaction caused by using electricity.

How a Salt Water Chlorinator (S.W.C.) works

A S.W.G. consists of a control box and cell. The cell has parallel Titanium plates coated with Ruthenium and Iridium. When the control box sends an electrical charge to the cell, this current creates a chemical reaction turning the salt water into Chlorine. The control board of the Chlorinator allows you to control the amount of Chlorine that is produced.

Salt should be added directly to the Pool water and the Pool swept with a pool brush until the salt dissolves. The salt water then passes through your Filtration System and lastly through the Chlorinator, converting the Salt into Chlorine, and then returns back to the Pool keeping your Pool sanitised! The initial dose of Salt needed depends on the volume of water in your Pool, this also determines what size Chlorinator is required.

Even though the S.W.C. does the work of dosing the Pool for you, you still need to test the Salt level separately to your normal testing. If the salt level drops too low, there won’t be enough in the Pool for the Chlorinator to convert into Chlorine. The ideal Salt reading for any Pool is 3500 - 4000 ppm.

The cell of an S.W.C. typically lasts around 3 – 5 years, although this will depend on usage of the Pool along with good maintenance and water balance. The Cell should be checked over by eye every season and cleaned with acid every so often to remove any scale build up. Most models can have a cell replaced without having to buy a whole new unit so this is something to consider when choosing your S.W.C. 

Having a Salt Water Chlorinator does not mean you have a Salt Pool!
