The CECHLO® MS system is an ion exchange membrane electrolyzer. This patented technology generates sodium hypochlorite at a high strength of 12% using the typical process for generating bulk gas or liquid chlorine but with a scaled-down technology that safely produces chlorine on site.

The robust CECHLO® MS poses none of the risks associated with the delivery or storage of hazardous chemicals and requires no special staff training or qualifications. It has low production and operational costs and is energy efficient. The proprietary DSA® electrode ensures reliable high performance.


  • Safely and economically produces chlorine gas (Cl2), sodium hydroxide (NaOH) and high-strength 12% sodium hypochlorite (NaClO) without the risks associated with delivery or storage of hazardous chemicals such as high-pressure chlorine 
  • More than 40 years of experience and improvement of ion exchange membrane electrolysis technology 
  • Long, stable operation and easy maintenance, with world-proven ion exchange membrane electrolyzer 
  • Used for water and wastewater treatment disinfection; bleach manufacturing; and wholesale chemical production
