(EDI) is to cleanse water quality by electro-deionization, which is an electrochemistry continuously purify water quality through ion exchange resin and current function: The ion exchange resin of E-Cell module exchange positive and negative foreign current function and consistently regenerating resin in order for high-quality water.

EDI equipment is divided into normal temperature and high temperature systems, the normal temperature(=35° C) sytem is used for wider occasion of biology requirement while the high temperature system is used for strict occasions, including injection solution and biological preparation of pharmaceutical industry.
