SMC salt chlorinator

Switch Mode technology

All of our dual-pole electrolysers use a power sourced by Switch Mode.
These sources present many advantages in comparison to conventional transformers, especially when used with a dual pole cell.


Chlorine production is effectuated by a cycle of polarisation interruption. This indicates that the electrolyser always works at a constant and optimal level in comparison to the performance of the cell. This has a fundamental incidence on the electrode's lifespan.

In a conventional electrolyser, however, the adjustment is made by varying the power supplied to the electrode so the unit's working range is adapted and performance is not managed.

In general, Switch Mode power supplies a better quality signal without peaks and allows precise control when there is a pole change.

Dual-pole cell technology

An electrolytic cell is composed of two immersed electrodes to which a difference of potential is applied. As the electrolytic is a conductor (salt water in the case of a pool), the applied difference of potential generates an electrical current that circulates through the electrodes and power source creating a series of chemical reactions inside the cell.

One of the results of these actions is the liberation of chlorine on the surface of the anode (positive electrode).

The quantity of chlorine produced on the anode surface is proportional to the electrical current it passes through.
To reach a production of chlorine which is sufficient, the electrical current or the electrodes surface must be heightened. For practical and technical reasons (electrode deterioration), the electrical current should not be heightened indefinitely. Therefore, the available production surface should be heightened by multiplying the number of electrodes.

Single pole cell

(Classic electrolyser)

Dual pole cell

(SMC exclusive)

For the same power source, the current which passes through the electrodes in a dual pole cell is much higher than a single pole, therefore, the system is much more efficient.

SMC 20 and 30 electrolyser installation

Installation of control module

Install the control module in a sheltered area in your technical room.
The box should be protected from splashes, rain and flooding.
The module should be situated in an easy to reach, ventilated area.

The command box should be 1.5 m maximum from the electrolytic cell and a minimum of 3.50 m from the pool.
The power supply of the module should be fitted with a 30 mA circuit breaker.
We recommend that the installation should be effectuated by a qualified technician.
It is imperative to install a "Pool-Terre" earth connection to eliminate stray currents that can lead to the corrosion of metallic elements present in your pool (pump, ladders, sealing parts...).

The SMC 20 and 30 salt electrolysers operate on a 230V single-phase supply.
To install your module easily, use the mounting kit supplied with your electrolyser.

Installation of the cell

The cell should be placed after the filter, the filtration pump and other additional equipment such as heat pump, solar panels... To mount the housing of the cell, use PVC glue. Once the glue has dried, insert the cell.

We recommend the installation of a three-way by-pass to optimise water circulation that passes through the cell. If circulation is too strong it can lead to pressure and vibrations that can damage your cell.

It is preferable to install the housing of the cell vertically allowing easy access to the cell.

On option: Automatic pH regulation

The pH measure shows if your pool water is acidic or basic. Water pH should be between 6.8 and 7.6.
Many elements can change water pH : variation of outdoor temperature, frequent pool use, poor dosing of chemical treatment products. The pH level becomes unbalanced :
- If lower than 6.8 : water is too acidic leading to corrosion of metallic parts in contact with pool water, favouring the development of algae and irritating eyes, skin and mucosa of swimmers.
- If over 7.6 : Water is too basic. Losing clarity, irritating eyes and mucosa of swimmers. Basic water can make swimming uncomfortable and chemical treatment products are less efficient.

Salt production heightens the basic aspect of water. To avoid any discomfort, we advise the use of a dosing pump. A dosing pump measures the pH level and regularly injects the adapted correction liquid.
A dosing pump is installed on the hydraulic circuit after the electrolytic cell as corrector liquid can damage the cell plates and their good working order.
