Product overview
Sodium hypochlorite (NaOCl) is an inorganic compound commonly supplied in aqueous solution (typically up to 20%). It is a strong oxidizer used for disinfection and bleaching. NaOCl can be produced by brine electrolysis or by dosing chlorine into caustic soda.

On-site generation advantages
Producing sodium hypochlorite at the dosing point reduces storage and handling of concentrated disinfectant and ensures the solution is generated in the required concentration and quantity. This approach minimizes dilution issues and provides a fresh disinfectant supply tailored to consumption.

How the generators operate
Profgenerator NaOCl MC units use salt electrolysis. A reactor containing an anode and a cathode is supplied with brine of defined concentration and direct current. Electrolysis yields sodium hypochlorite and hydrogen gas; hydrogen must be safely vented outside the building.

Models and construction variants
The NaOCl MC series is available in three nominal outputs: 30, 60 and 90 g Cl2/h. Each output can be supplied in two construction variants (I or II), which differ by salt tank capacity and finished-product tank capacity.

Application of sodium hypochlorite

• Disinfection of drinking water, food-industry water and bathing water;
• Reduction of bacterial load;
• Disinfection of cooling and circulating waters in chemical and paper industries, refineries, CHP and heating plants, and cooling towers;
• Washing and disinfection of fruits and vegetables;
• Protecting water supply networks against secondary microbiological contamination.

Characteristics / technical specifications

• Chemistry: sodium hypochlorite (NaOCl) — strong oxidizer; typical aqueous solutions up to 20%.
• Manufacture: brine electrolysis or chlorine dosing into caustic soda.
• Operation: brine flows through a reactor with anode and cathode; direct current applied to electrodes.
• By-product: hydrogen gas produced during electrolysis; requires safe external venting.
• Available outputs: 30 g Cl2/h, 60 g Cl2/h, 90 g Cl2/h.
• Construction variants: Variant I and Variant II differ by salt tank and finished-product tank capacities.
• Use case: on-site dosing for disinfection to reduce storage, dilution handling and ensure fresh disinfectant supply.
