Astrapool E-Next 21 Salt Chlorinator, 21 gr/h

The E-NEXT range of salt chlorinators provides a high degree of automation, allowing you to relax and fully enjoy your pool.

They are designed to disinfect pools of up to 180 m³.

Thanks to their compact design, they can be installed in most equipment rooms, even the dampest ones, thanks to their IP45 protection.

Its features are nothing short of impressive: it has a gas detector that will immediately stop the chlorinator if there is no flow in the pipe where it is installed, thus preventing chlorine gas from accumulating at any point in the installation and the consequent risk of a burst caused by overpressure.

It also includes a warning light to alert you when the salt level in the pool water is low, so you will not have to take inconvenient measurements constantly. Remember that for this chlorinator model, the optimum salt level in the water should be between 4 and 6 g/l.

You will not have to worry about cleaning the cell either, as this operation is carried out automatically every 2–3 hours by reversing the polarity in the cell.

Chlorine production can be set to 50%, 75%, or 100%, as required.
