Fact Sheet
E-Cell-3X Stack
Industrial Electrodeionization (EDI) Stacks
E-Cell*-3X is designed to:
 Provide Ultrapure
Water for industrial
applications includ-
ing Power, Semicon-
ductor, 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 recir-
culation, 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
