IP-VNXHH-2

Summary

Product identification

The IONPURE® VNX55-HH series consists of High Hardness Continuous Electrodeionization (CEDI) Modules. These modules utilize proven Ionpure® CEDI technology to produce high purity water, optimized to handle high feed water hardness while delivering ultrapure water quality at high flow rates, particularly for the power industry.

Key features include:

• Typically > 16 MΩ-cm product water resistivity
• 2 ppm (as CaCO₃) max feed water hardness
• Can often operate on single-pass RO permeate
• Resin, membrane, and module construction are optimized for feed water hardness tolerance
• Eliminates the need for acid/caustic, neutralization systems, or tank exchanges
• Offers significantly lower operating cost compared to conventional ion exchange systems
• Robust, leak-free sealing with through-port gasket
• Continuous production of consistent quality
• Junction box for convenient and safe power connections

Combining multiple VNX55-HH modules allows for simplified system design for high flow rate applications up to and greater than 1,000 gpm.
