Understanding Saltwater Chlorinators

Anatomy of Saltwater Chlorinators & How They Work

Hearing the term “saltwater chlorinator” for the first time can be a bit confusing. You may be thinking, “If it’s a saltwater pool, there’s no chlorine – right? Why would it need a chlorinator?” This question is common, and the explanation is much simpler than it may seem. Salt water pools aren’t actually chlorine free. They still have chlorine in them – they just obtain it in a different way than chlorine pools do. Saltwater pools use a special generator to transform dissolved salt into chlorine. The special generator is called – you guessed it – a salt water chlorinator.

How Do Saltwater Chlorinators Work?

In non-scientific terms, the salt you put into your pool dissolves into the water. The water then passes through the saltwater chlorinator, which is home to an electric current. By passing through the electric current, the dissolved salt is turned into chlorine. At the end of the day, no matter the type of pool you have, chlorine is what keeps it clean. 

What Makes Up a Saltwater Chlorinator?

There are 2 main parts to a salt water chlorinator – the cell and the control board. The cell is where the action happens. It’s where the salt is converted into chlorine. The control board, on the other hand, is where the heavy lifting happens. Its responsible for generating the electricity that later passes through the cell. As a pool owner, you’re in control of the control board, which means you control how much chlorine goes into your pool.

Understanding what a saltwater chlorinator is and what it does will give you a better understanding of how to care for your saltwater pool. Pool maintenance can be tricky at first, but with a little help, caring for your pool couldn’t be easier.
