How does the external control for an MEMDOS DX motor-driven diaphragm dosing pump work?

The DX control unit of the MEMDOS DX has a digital pulse input, which can be actuated by any controller, for example a TOPAX controller or an SPS. The external control via an ON/OFF switch briefly switches off the DX control of the pump, and is therefore not possible.

Flow-through chlorine electrolysis

What makes the SALT-WATER-LIGHT process environmentally friendly?

SALT-WATER-LIGHT is a disinfection process for swimming pools. The salt dissolved in the swimming pool water (e.g. cooking salt, NaCl) is converted into a chlorine compound during recirculation. The chlorine necessary for disinfection is therefore produced directly in the water. Conventional chlorine sources such as chlorine gas or chlorine bleach are highly aggressive materials and must be stored by the swimming pool. With the SALT-WATER-LIGHT process, this is not necessary.

Is this technology only suitable for large or public swimming pools?

No, of course not. The smallest system is suitable for pool sizes between
10 and 50 m2. Only one conversion/filter unit is needed, and is today provided as standard.
