How Salt Water Chlorinators Work.

A Salt or Mineral water chlorination system, is a chlorine generator that produces its own, 100% available chlorine, in-situ to meet the chlorine demand & sanitation needs of your swimming pool.


There are no chlorine chemicals to purchase, handle or store making it a far safer alternative to manual or semi automatic chlorine dosing systems.


A Salt Water chlorinator consists of two parts:

  1. Power Pack  - supplying low voltage power to the cell.

  2. Cell  - an electrolytic cell

As the salt water passes over the electrolytic cell, the process of electrolysis produces 100% available chlorine which is then evenly dispersed throughout your swimming pool during the normal filtration cycle.

The advantages of salt water chlorination for swimming pools, apart from the sanitising effect are the pleasantness of the water, lack of red eyes from prolonged bathing, convenience and safety, lower chemical costs and the fact that asthma and hayfever sufferers can now swim in and under water without adverse symptoms.

Installation of a Salt Water Chlorinator

The Salt Chlorinator Cell is plumbed into the return to pool line after the filter, heater and pressure pool cleaner line.


The Salt Chlorinator Power Pack is mounted on a wall or post in close proximity to the cell.

Salt or a Mineral blend mix is added to the pool water, at a rate of approximately 5 kilograms for every 1000 litres to achieve a desired salt level of 5000 ppm (parts per million).


This salinity level is about 1/7th (one seventh) the strength of sea water, it is so mild it is actually pleasant to taste.

Salt needs to be replaced only when water is lost from the pool (except via evaporation). Evaporation of water will only concentrate the salt level and will be diluted again when the pool level is topped up.

Gas and electric heaters require the salt chlorinator cell to be installed at a minimum of 1 -2 meters from heater outlets. All Salt Chlorinator Cells must be installed in a position that ensures the gas detection sensor functions as designed.
