EDI E-Cell 3X Stack

Summary

Product identification

The E-Cell-3X Stack is an industrial electrodeionization (EDI) stack, part of the E-Cell product line. It is designed to use electrical current to provide ultrapure water.

Key features include:

• Delivers premium performance with high product water quality and low energy consumption.
• Minimizes cleaning requirements at higher feed water hardness levels using counter-current operation.
• Guaranteed leak-free with a standard 3-year prorated warranty.
• Operates continuously and requires no caustic or acid for regeneration of ion exchange resin.
• Requires no brine injection or concentrate recirculation.

Typical Applications:

• Ultrapure water for rinsing of semiconductor chips, solar panels, and other microelectronics.
• Demineralized boiler feed water for high-pressure boilers.
• Ultrapure water for electrolyzer green hydrogen generation.

Quality Assurance

• CE, RoHS, CSA & EAC marked.
• Manufactured in an ISO 9001 and ISO 14001 facility.
• Certified with UKCA.
• Halal certified by the Islamic Food and Nutrition Council of America (IFANCA®).
