Chlorine generator (sodium hypochlorite) from salt by electrolysis CHLORINSITU

On-site Chlorine Generator

Generators from 40 to 3,500 g/h of chlorine.

No need to buy the chemical and manipulate it.

  • Drinking water chlorination.
  • Swimming pool water chlorination.
  • Chlorination of process water in industry.

On-site Chlorine Generators from salt pellets by Electrolysis

With the sodium hypochlorite (Chlorine) generator there is no need to transport, store or handle it. In contrast, generator equipment converts common salt (sodium chloride) into chlorine, hydrogen and sodium hydroxide at the point of use.

Very simple

Electrolysis is a technically advanced and cost-effective alternative for producing chlorine (bleach) and other disinfectants. Chlorine generated from common salt can be added directly to water as hypochlorous acid (HOCI) or stored temporarily as sodium hypochlorite (NaOCI). Production of sodium hydroxide.

Very safe

ProMinent’s electrolysis system completely eliminates the storage, transport and handling of hazardous chemicals. The same settings (CHLORINSITU V Plus / CHLORINSITU IV Compact) can be used to generate chlorine and calibrate pH values. The electrolysis system is a vacuum-operated system, which ensures maximum operational safety.
