Commercial Water Deionizers

Culligan deionization products reduce total dissolved solids (TDS) from water by means of ion exchange resins. This complex process results in high-purity water from a system that is easy to use and maintain.

Deionization solutions can be customized to your exact business needs. Individual models are designed for easy operation and provide a cost-efficient supply of high-purity water to your business.

Portable Exchange Deionization

Portable DI systems deliver a constant supply of quality water to operations large and small, without a capital investment. Regeneration or exchange is provided by a Culligan Dealer. This system reduces on-site labor and regenerant chemical handling.

Automatic Deionization

Premier Series DI offers automatic deionization and regeneration of depleted resins.
