How does a salt cell generate chlorine in swimming pools?

Presidential Pools of Florida is a leading provider of pool equipment and services in the state. One of their most popular products is the Salt Cell Chlorinator, which uses salt to sanitize swimming pool water. In this article, we’ll take a closer look at how a Salt Cell Chlorinator works and why it’s a great option for keeping your pool clean.

How Does a Salt Cell Chlorinator Work?

A Salt Cell Chlorinator is an automated device that uses electrolysis to produce chlorine from salt. The process works by passing a low voltage electric current through the salt water, which causes the salt molecules to break down into their component parts: sodium and chlorine. The chlorine then sanitizes the water by killing bacteria and other microorganisms.

The Salt Cell Chlorinator is installed in the pool’s plumbing system and is connected to a control panel that allows you to adjust the chlorine output. The system includes a salt cell that contains a series of titanium plates coated with a thin layer of precious metals, such as ruthenium and iridium. These metals act as a catalyst to speed up the electrolysis process and prevent the buildup of calcium and other minerals on the plates.

Benefits of Using a Salt Cell Chlorinator

There are several benefits to using a Salt Cell Chlorinator to sanitize your pool water. Firstly, it eliminates the need to handle and store dangerous chemicals such as chlorine and other pool sanitizers. This makes it a safer and more convenient option for pool owners. Additionally, the Salt Cell Chlorinator produces a consistent and steady flow of chlorine, which helps to keep the water clean and clear.

Another advantage of using a Salt Cell Chlorinator is that it can save you money in the long run. While the initial cost of installation may be higher than traditional chlorine systems, the ongoing maintenance costs are generally lower. You won’t need to purchase as much chlorine, and the Salt Cell Chlorinator requires less maintenance than other systems.

Finally, using a Salt Cell Chlorinator is a more eco-friendly option. It reduces the amount of chlorine that is released into the environment, and the salt used in the process is natural and renewable.


In summary, a Salt Cell Chlorinator is a safe, convenient, and cost-effective way to sanitize your swimming pool. It works by using electrolysis to produce chlorine from salt, eliminating the need for traditional pool sanitizers. If you’re interested in installing a Salt Cell Chlorinator in your pool, be sure to contact Presidential Pools of Florida for expert advice and installation services.
