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.

  • Quickly create a tailored RO solution with the configurator tool for maximum cost-effectiveness.
  • Reduce startup time with worldwide technical support for installation.
  • Save on utilities with low-energy membranes featured on the IW RO system that require smaller pumps.
  • American-made construction allows for a Culligan® quality guarantee. 


  • Galvanized steel frame mount with anti-corrosion paint coating.
  • 5 micron pre-filtration with PVC housing.
  • Multi-stage high-pressure pump with high-grade AISI 316 Stainless Steel, dry running protection, and low-noise/high-efficiency IE3 motor.
  • Ultra-low-pressure, high-rejection 8" membranes.
  • Culligan® Smart Controller automates operation with digital flow meters, pressure transducers, and conductivity measurements, along with other advanced functionality more commonly found in PLC controls.
