IP-VNX28-2

Summary

Product Identification

The Ionpure® VNX28-2 is a Mid-Range Flow Continuous Electrodeionization (CEDI) Module. It is designed with proven CEDI technology to produce high purity water.

Key features:

• Generates mixed bed deionized water without the use of chemicals
• No need for acid/caustic, neutralization system or exchangeable DI tanks
• Consistent continuous production instead of batch cycle variability
• Most compact footprint in the industry
• Can be operated in both horizontal and vertical configuration
• Significantly lower operating costs than conventional ion exchange
• Robust leak free sealing with through-port gasket
• Large flow modules reduce system cost and simplify skid design
• Connection fittings are included
• On-board junction box

The nominal flow rate is 27.5 GPM (6.2 m³/hr). The module can be used in single or multiple module arrangements. Proprietary Flexmount™ connectors create a support system, eliminating the need for a skid.
