Mpure 36

Summary

Product identification

The RALEX® EDI STACK MPure™ 36 is an electrodeionization (EDI) module used for the production of high purity water in the power, semiconductor, and chemical industries. This technology replaces mixed bed ion exchange, offering continuous high-purity water production without hazardous regeneration chemicals.

MPure™ stacks incorporate RALEX® ion exchange membranes developed by MEGA. The MPure™ 36 produces 16 to 18 MΩ·cm product water quality at very high recovery. These stacks are designed to replace mixed bed ion exchange at flow rates from 5 to 500 m³/h (20 to 2000 gpm) and beyond.

Key features include:

• Stack interconnection capability for low cost system construction
• High flow rate blocks, flows up to 45 m³/h (200 gpm) per block
• High deionization with recovery up to 97.5 %
• Robust design: no internal or external leaks
• Small footprint: ideal for operation inside containers
• Voltage stability
• Effective replacement for competing EDI technology
• Complete OEM engineering package
