Electrolysis Systems
No chemicals required
What a great idea: no chemicals to be transported and no need to store and handle hazardous substances. Instead, sophisticated systems use harmless sodium chloride – ordinary salt – to produce chlorine, hydrogen and sodium hydroxide.
It's really very simple
Electrolysis is an economically sensible and technically perfected alternative to the metering of sodium hypochlorite or other disinfectants. The chlorine generated from sodium chloride can either be metered into the water directly as hypochlorous acid (HOCl) or temporarily stored with the sodium hydroxide generated in the form of sodium hypochlorite solution (NaOCl).
Reassuring to know
Disinfection with sodium chloride is completely safe. There is absolutely no need for the storage, transport and handling of hazardous chemicals when using a ProMinent electrolysis system. You can generate chlorine and perform pH value correction with a single system (CHLORINSITU V Plus / CHLORINSITU IV compact). ProMinent electrolysis systems are designed as negative pressure systems – operating safety comes as standard.
We offer a range of solutions for potable, process and swimming pool water. You can find various application combinations in the table. If you have a specific problem, don't hesitate to ask our specialists. If they don't have a solution ready to hand, they will find one. That's guaranteed.
