Salt electrolysis systems
Salt electrolysis systems for swimming pools: chlorine made from the salt in the water
A salt electrolysis system is a chlorinator that produces chlorine from the salt dissolved in the pool water, without handling chlorine products. Here Q-Tech brings together six brands, from 7 to 50 g/h, for anyone who wants automatic disinfection with salt.
The AstralPool Energy Sel 71652 is an outlet unit: new, unused and in its original packaging.
How to choose a brand
Q-Tech has selected the brands in this collection on technical criteria.

Summary for information purposes only, prepared by Q-Tech in November 2026 from the technical data sheets each manufacturer publishes, to help you get your bearings among the brands we sell. It is general and indicative: manufacturers update their data and a summary may contain errors, so each product page and the manufacturer's documentation always prevail, without prejudice to your rights as a consumer (Legal Notice). It is common for customers to change their mind once they know each brand's strengths, or to find that a feature they liked is not essential in their case.
A salt chlorinator runs for many years in your pool, and a choice that does not fit your installation shows up in running costs and in wear on the cell. If you want to decide with the data of your own case, you can book our professional technical advice (a paid service): an Expert Technician reviews the features of your pool and installation with you and guides you with Q-Tech's experience, under an obligation of means (Legal Notice).

Data according to each manufacturer.
How to choose a salt electrolysis system
- Choose the output by your pool volume: each manufacturer states on the data sheet how many m³ each model covers.
- To work with little salt, check the salinity: the Mr. Pure works from 1 g/l, according to Aquark; for even less, see the Salt hydrolysis systems.
- To run filtration, lighting and pH from the chlorinator, Hidrolife and BIONET have relays; modules in Chlorinator accessories and modules and cells in Replacement cells and electrodes.
Applications
- Private pools moving from chlorine tablets to salt; the salt is not consumed.
- Replacing a salt chlorinator that no longer produces.
- Plant rooms that centralise disinfection and control.

Frequently asked questions
What chlorine output do I need?
The one the manufacturer gives for your volume: according to Hayward, the 16 g/h Salt & Swim 2.0 covers up to 75 m³ and the 33 g/h model up to 150 m³.
Does the pH need to be controlled?
Yes. Manufacturers ask for it to be kept within a range (between 7.0 and 7.4 for the Energy Sel, according to AstralPool); units with pH control or the regulators in pH and chlorine control keep it there.
See the whole family in Salt chlorinators: the aim is disinfected water with just enough salt.
