No limits for water quality at any quantity.

No limits for your water quality regardless of quantity - the Culligan® G3 Reverse Osmosis system processes water to help meet your most demanding and exacting industrial requirements. The durable reverse osmosis membrane processes large volumes while reducing water waste; you can manage the system using a touch panel electronic controller. Better quality water improves industrial processes by reducing contaminants (Contaminants may not necessarily be in your water.) that corrode and clog equipment, so your investment in the Culligan® G3 RO benefits your operations for years to come.
