Request Information
Designed to meet the needs of the most demanding industrial and municipal applications.

Available in a variety of configurations to cover flow requirements from 22 to 200 GPM with salinity levels up to 3000ppm of TDS. Using an innovative modular design, Culligan® is able to offer the highest quality construction and speedy delivery times at very competitive pricing.

Low-pressure membrane technology can remove over 99% of contaminants such as dissolved minerals, bacteria, and other impurities; producing water suitable for high-purity applications like boiler feed and ingredient water for food and beverage production.

All units are assembled and tested in Culligan®'s Commercial & Industrial facility in Libertyville, Illinois and shipped skid-mounted for simple installation and easy start-up.
