Integrating pretreatment filer (quartz sand and activated carbon), double stage reverse osmosis membrane, EDI module, 150 liters buffer tank (for 1st stage RO water), 250 liters stainless steel tank (SUS304, for Edi water), pure water supplying and tube circulation system into one body, Central R2E 250/500´s output ranges from 250 to 500 liters/hour.

The Edi / deionized water´s resistivity is more than 15 MΩ.cm, in the low running cost. It meets the requirements of pure water for mass production and lab central water supply.
