E-Cell* MK-3Mini Stack
Electrodeionization (EDI) Stacks for Low Flow Applications
E-Cell* MK-3Mini is designed to:
 Provide Ultrapure Water for industrial applica-
tions including Power, Semiconductor, and
General Industry.
 Produce Mixed Bed quality water on a contin-
uous basis.
 Require no caustic or acid for regeneration of
mixed bed resin within the stack.
 Be leak free, guaranteed
 Eliminate brine injection and concentrate recircu-
lation, simplifying system design.
Description and Use
MK-3Mini E-Cell stacks are Electrodeionization
(EDI) stacks which use electrical current to deion-
ize and polish reverse osmosis (RO) permeate wa-
ter. The product water for the MK-3Mini is at an
Ultrapure level required in today’s most demand-
ing applications.
Typical Applications
 Pharmaceutical
 Laboratory
 Semiconductor/Microelectronics
 General Industry
Quality Assurance
 CE, UL & CSA marked
 Manufactured in a ISO 9001:2000 facility
