IP-VNX50E-2

Summary

Product identification

The Ionpure VNX50E-2 (or VNX50-E) is a Continuous Electrodeionization (CEDI) module designed to produce high purity water. It is optimized for high recovery and the ultrapure water demands of the microelectronics industry.

Key features include:

• Guaranteed 18 megohm-cm product Resistivity, optimized for microelectronics and UPW systems
• Silica and Boron removal ≥95%
• Sodium and Chloride removal ≥99.8%
• 98.5-99% recovery for loop usage and high water savings
• No need for acid/caustic, neutralization systems or tank exchanges
• Significantly lower operating cost compared to conventional ion exchange systems
• Robust, guaranteed leak free operation
• Continuous production of consistent quality
• Low operating costs and compact footprint
• 50mm butt weld natural Polypropylene or PVDF connection kits and drawings available
• Each module has a nominal flow rate of 50.0 gpm (11.4 m3/hr). Multiple 50 gpm modules provide for system designs with flow rates up to, and greater than 1000 gpm.

The module part number for ordering (for vertical or horizontal installation) is IP-VNX50E-2. Each VNX module has four process connections: Feed, Concentrate Feed, Product, and Reject.
