Salt Water Chlorinators
A salt water chlorinator is by far the most popular method of sanitizing your pool. The concept has been around for many years, and it is probably the simplest and most convenient way to keep your pool healthy.
Selecting a salt water chlorinator
There is a range of models on the market to suit nearly every application.
When selecting a salt water chlorinator, you should take some time to ensure you are getting what you need. Chlorinators come in a range of sizes (relating to the amount of chlorine they can produce in an hour) and you should choose a model that is suited to the size of your pool, and also how much use your pool gets. In general, the average 40,000L back yard pool in Queensland will need a chlorinator capable of producing between 20 and 30 grams of chlorine per hour, but there are many factors that can vary this, so be sure to get some professional advice before you invest in this equipment.
Be aware that not all chlorinators are created equal. The part of the chlorinator that will eventually wear out is the salt cell (electrode). How long this cell lasts depends on the quality of the material that was used in its construction, and how well it has been maintained. Given the replacement cells can cost many hundreds of dollars, it is worth asking the question about the warranty provided on the salt cell.
TIP: Make sure the warranty is a replacement warranty not a Pro Rata warranty
Pro rata warranties only offer a discount off the cost of the replacement
Types of Salt Water Chlorinators
There are many options available.
Standard vs. Self-Cleaning Chlorinators
Probably the biggest difference is between standard chlorinators and self- cleaning chlorinators.
Standard chlorinators require the cell to be removed about once per month and soaked in a solution of acid and water to dissolve the calcium build up. Self-cleaning chlorinators reverse polarity on a regular basis to prevent the calcium scale accumulating on the cell.
Chlorinators with battery back-up timers
Other options that are worth looking for are battery back-up timers which keep all the settings on your timer if you have a black out or operate on off peak power, and run-dry safety protection. This system senses when the cell has adequate water flow, and turns off the pump and chlorinator when it recognises there is a problem. This can prevent costly repairs to melted pumps that have run without water.
Chlorinators with built in pH control
As people are becoming more educated about the importance of correct pH in the pool, salt water chlorinators with in-built pH control are becoming more popular. These units have a sensor to measure the pH in the pool water, and automatically dose acid as required to maintain the correct pH.
We have all these options on display in our stores and our experienced staff will guide you through the selection process to ensure you get a chlorinator that suits both your needs and your budget.
