E-Cell* MK-3 Stack

Industrial Electrodeionization (EDI) Stacks

E-Cell* MK-3 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-3 E-Cell stacks are electrodeionization (EDI)

stacks which use electrical current to deionize and

polish reverse osmosis (RO) permeate water. The

product water for the MK-3 is at an Ultrapure level

required in today’s most demanding applications.

Typical Applications

 Semiconductor

 Microelectronics

 Power Generation (NOx, Boiler Feed)

 General Industry

Quality Assurance

 CE, UL & CSA marked

 Manufactured in a ISO 9001:2000 facility
