Electrolyser cells for pools

All you need to know about pool electrolyzer cells

For saltwater pool owners, the electrolysis system is an ideal solution for effective and natural water treatment. At PoolPlanet, we have selected high-quality replacement cells from the brand CCEI, a brand recognized for its reliable and efficient equipment. Our cells are compatible with many electrolyzer brands, including LIMPIDO®, Zelia, and many others.

How to replace an electrolysis cell?

Changing an electrolyzer cell is a simple operation, but it requires following a few essential steps to ensure the system functions correctly. First, make sure you choose a cell compatible with the equipment you are using.

Cut off the electrical power to the electrolyzer to avoid any risk of electrocution.

Unscrew the used cell by gently removing it from its location. It is usually fixed with threaded fittings, hose clamps.

Clean the connections to remove any lime deposits or impurities that could hinder the transmission of electrical current.

Install the new electrolysis cell, making sure to respect the mounting direction indicated by the manufacturer.

Reconnect the electrical connections, then screw the cell back onto the water circuit.

Restore power and test the operation of the electrolyzer, checking that chlorine production is correct.

If the new cell does not work immediately, it may be useful to check the electrolyzer settings and ensure a good salt level in the water.

What is the lifespan of electrolyzer cells?

The lifespan of a cell varies depending on several factors:

• Regular maintenance: Good maintenance helps descale, reduces the appearance of wear signs, and extends the product's lifespan.
• Salt level in the water: A salt level that is too low or too high can accelerate the wear of the cell plates.
• Daily use time: A cell that operates continuously at full power will wear out faster.

On average, an electrolyzer cell lasts between 3 and 5 years. Some models can exceed this duration if maintenance is properly carried out.

How to clean your electrolyzer cell?

Regular cleaning of your cell is essential to prevent limescale accumulation on the electrodes and ensure optimal chlorine production.

1. Turn off the electrolyzer and remove the cell.
2. Screw the cell onto a cleaning plug.
3. Pour household white vinegar into the cell and leave for 6 to 12 hours to dissolve limescale deposits (avoid using acid). Repeat the operation if necessary.
4. Rinse thoroughly with clean water.
5. Reassemble the cell and put it back into service.

Warning: never scratch the electrodes with a metal object, as this can damage their coating and reduce the cell's lifespan.

What types of cells are available?

At Pool Planet, we offer several types of products compatible with the electrolyzers we provide. You will mainly find cells from the CCEI brand, such as Zelia and Limpido cells of different sizes depending on the power of your electrolyzer. CCEI is a recognized manufacturer of treatment systems to ensure optimal disinfection of your pool.
For winterization, we also offer empty cells to allow you to clean your cell and maintain the operation of your pool or filtration system. The electrolyzer cell is the key equipment for your pool's disinfection and the salt electrolysis process; it is recommended to maintain it by cleaning it 2 to 3 times a year to keep it in good condition and avoid any problems.

How does a pool electrolyzer work?

An electrolyzer works thanks to a chemical reaction called electrolysis. Here's how salt is transformed into disinfecting chlorine:

1. Saltwater flows through the transparent cell containing titanium plates/electrodes.
2. An electric current is applied, causing the decomposition of salt (NaCl) into active natural chlorine (sodium hypochlorite).
3. The active chlorine disinfects the water by eliminating bacteria and algae.
4. The chlorine reconverts to salt under the effect of UV rays, allowing for a continuous disinfection cycle.

Thanks to this treatment, it is no longer necessary to add chemical chlorine, which offers a more ecological and comfortable solution for bathers' experience.

What are the prices of electrolyzer cells?

The price of an electrolyzer cell depends on its power and compatible electrolyzer model. The larger/more powerful a cell is, the higher its price will be. Cells with particular technology can also drive up the price.

On average, here is a price range for purchasing our standard cell range: between €250 and €1000 depending on the model and the required power.

How to test an electrolyzer cell?

If you notice a drop in chlorine production, it is possible that your original cell is at the end of its life or clogged. Here's how to check:

Check the electrolyzer display: Some models indicate an error if the cell is faulty.

Test the electrical voltage at the terminals with a voltmeter: A functional cell should receive a correct voltage (generally between 6 and 24 volts depending on the model).

Perform a test: Measure the free chlorine level in the water. A lack of chlorine may indicate a faulty cell.

Clean the cell and retest. If production does not restart after maintenance, it may be time to replace it.
