The Astral combined electrolyser and pH regulation offers
automatic management of your chlorine production and regulation of pH.
You can benefit from crystalline water limiting to a maximum the manipulation
of treatment products.

2 in 1 : for simplified installation, saving space in your technical shelter.
The module allows you to be free from manual intervention concerning
chlorine and pH maintenance in your pool.

Two models are available : Astral SEL 40 for pools up to 40m³
and Astral SEL 60 for pools up to 60m³.

Advantages of the Astral combined electrolyser and pH regulation

Easy installation : The transparent sensor support, injector, earth connection, flow switch and cell housing ensures easy, compact installation on the hydraulic system.

Security : The transparent cell housing features a security precaution - when pump flow is interrupted or insufficient, the flow detection stops chlorine production and does not damage your installation.

Efficient and economical :The Astral combined electrolyser and pH regulation totally automates you water treatment management for your pool water. This optimises the efficiency and consumption of disinfecting products, making important economies.

Composition of the Astral combined electrolyser and pH regulation

Astral SEL electrolyser

The Astral SEL is composed of :
- An ABS command module with wall mounting plugs.
- A transparent cell support to be installed on the pipework.
- An electrolyte cell.


The housing uses an easy to use control panel that indicates the status of the unit
by means of luminous indicators.

Transparent cell support
Astral combined electrolyser and pH regulation
The transparent cell support is installed on your pipework, allowing the visualisation of the cleanliness of electrodes. Integrating a pH sensor, (a), an injector (b) and a flow detector (c). It's earthed connection (d) ensures the evacuation of stray currents that could attack metallic parts present in the pool water.

Astral combined electrolyser and pH regulation cell

Transparent cell support


The cell is composed of titanium plates coated with ruthenium and iridium oxide and is self-cleaning by polarity inversion. This guarantees a quality production of chlorine and contributes to the long lifespan of the cell.

Shutter detection
If your pool is equipped with and automatic shutter and it is in a closed position, you can reduce chlorine production of your electrolyser to avoid a concentration of chlorine that could harm the shutter slats. The Astral SEL manages automatically the production of chlorine depending on the position of your shutter on the condition that there is a contact present on your shutter installation.

Factory set to diminish production by half, Astral SEL can equally be set to deal with specific constraints.

Astral pH regulation

Astral pH is a simple and efficient analysing and regulating system.
Its peristaltic pump allows the treatment of pools up to 60m³.

Supplied with a complete connection kit, Astral pH is installed easily
and quickly on the majority of filtration systems. Its connection is made
on an electric power supply conform to norm C-15-100
(protection by 30 mA circuit breaker).

The pH sensor and pump injects automatically the quantity of pH
corrector adapted to the pool water status.
