Fact Sheet
E-Cell-3X Stack
Industrial Electrodeionization (EDI) Stacks
E-Cell*-3X is designed to:
Provide Ultrapure Water for industrial applications including Power, Semiconductor, and General Industry.
Produce Mixed Bed quality water on a continuous basis.
Require no caustic or acid for regeneration of ion exchange resin within the stack.
Be leak free, guaranteed.
Eliminate brine injection and concentrate recirculation, simplifying system design.
Description and Use
E-Cell-3X stacks are electrodeionization (EDI) stacks which use electrical current to deionize and polish reverse osmosis (RO) permeate water. The product water for the E-Cell-3X is at an Ultrapure level required in today’s demanding applications.
Typical Applications
Microelectronics
Power Generation (NOx, Boiler Feed)
General Industry
Quality Assurance
CE, UL & CSA marked
Manufactured in a ISO 9001:2000 facility
