AGC Chemicals (Thailand) Co. Ltd (ACTH) produces caustic soda and chlorine with old ion exchange membrane (IEM) electrolyzers in their Phrapradaeng factory. In this project, the old electrolyzers are replaced by the latest, i.e. the most advanced, IEM electrolyzers with the newest membrane in order to reduce power consumption largely, which leads to the reduction of environmental burden and production cost.

Compared to currently most used IEM electrolyzers, the latest electrolyzers have multiple improvements in electrodes, inner structures and membrane and these improvements contribute to lowering the resistance and power consumption.
