High purity water is essential to industries such as aquariums, car washes, food manufacturing and pharmaceuticals, and laboratory and industrial facilities. Often known as “DI systems,” Portable Exchange Deionization and Demineralization systems generate the high purity water these businesses require by removing ions from water, eliminating copper, iron, sodium, and sulfate.

DI High Purity Tanks and parts.

Portable DI tanks run from 0.5 to 45 cubic feet in capacity and often incorporate different ion exchange resin types and tank sizes.

We carry exchange tanks, heads and fittings, including in/out heads with and without fill ports, stainless steel bands, threaded connections, instrumentation and monitoring components, cartridge systems, replacement filters and parts, and complete distributor assemblies and quick disconnect fittings.
