Product Description

EDI-Series Electrodeionization Water Purification Systems

EDI-Series Electrodeionization Systems provide superior ultrapure water production for demanding applications in power generation, pharmaceutical, and semiconductor industries. These advanced systems use electricity to continuously drive ions through deionization resins and ion-selective membranes, eliminating the need for chemical regeneration.

Key Advantages

Chemical-free operation with no regeneration requirements
Modular design for easy expansion and parallel arrangements
Continuous operation with consistent high-purity output
Four flow ranges available from 1 to 7 gallons per minute
