The Silex deionizers are an convenient and economical choice for producing deionized water. These units are ideal for spotfree rinse applications or wherever deionized water is needed. The silex housing contains a pack of ion exchange resin that is easily exchanged when the system has become exhausted. Multiple DI columns can be added for larger capacity applications. Optional components such as digital megohm meter, recirculation pump and sub-micron filters are available for the system as well.  The certificate exchange program makes exchanging resin packs very  simple.
