The Sodium Hypochlorite Generating Device is engineered to maintain a consistent concentration even when facing fluctuating inflow conditions. This efficiency is achieved through the incorporation of a two-stage cooling water inflow method, which enhances cooling efficiency during the generation of sodium hypochlorite. The system operates on the principle of on-site production, yielding a sodium hypochlorite solution with a concentration ranging between 0.8 and 1.0% NaOCl. The generator's composition and operation are optimized to ensure reliability and effectiveness for users seeking a stable supply of sodium hypochlorite. Users will benefit from the generator's adaptability to varying input conditions and its capability to consistently deliver the necessary chemical concentration, making it suitable for various industrial and sanitation applications.
