Introducing: the New IW Reverse Osmosis System

A completely flexible solution for high-purity water in half the time.

The new Culligan IW Reverse Osmosis system enables maximum cost-effectiveness by using some of the most innovative industrial technology in the industry and American-made design.

Its configurable layout allows for as many as 100 design variations and features to create the perfect industrial RO system to match your facility. This variety of modular configurations can cover flow requirements for industrial applications from 22 to 200* GPM.
