Collection: Ultra High Purity Demineralizer (DI) Systems

Commercial & Industrial Demineralizer

Crystal Quest® Commercial and Industrial Demineralizer (DI) Systems are designed and manufactured for industrial applications that use water low in mineral content. Deionized water is a type of purified water that has the mineral ions removed. Examples of these minerals include, but are not limited to sodium, calcium, iron, copper and chloride. Deionized water is obtained by exposing influent water to an electrically charged deionizing resin media bed that attracts and binds to the salts, removing them from the water. Because most of the impurities are removed from the water, deionized water is mostly pure, however it is not normally recommended for drinking purposes as some mineral salts are essential nutrients.


Deionized water has many applications, most of them scientific or industrial. Some of the ways deionized water is used include, but are not limited to: 

  • Microbiology experiments as a medium
  • Lead-acid batteries used in today's motor vehicles
  • Steam irons operated by dry cleaners ensuring well-ironed clothing without mineral residue
  • A medium or additive in many pharmaceutical and cosmetic products; it is desired for its low chemical reactivity
  • Manufacturing of electronic semiconductors as well as medical devices

And are used in Clinics, Pharmaceutical Industries, Electronics manufacturers, Breweries
