High-flow module, designed to produce high-purity water for the microelectronics industry

Discontinued product


The VNX55-E high flow module is designed with proven Ionpure® continuous electrodeionization (CEDI) technology to produce high purity water. Performance has been optimized for high recovery and the ultrapure water demands of the microelectronics industry.

Each VNX55-E industrial module has a nominal flow rate of 55 gpm (12.5 m³/h).

Multiple 55 gpm modules provide for simplified system design with flow rates up to, and greater than 1,000 gpm
