IONPURE VNX-MAX and VNX-MINI are high-flow CEDI(Continuous Electrodeionization)modules designed as an edi module water treatment solution for producing ultrapure deionized water equipment.The VNX-MAX delivers nominal 15 m³/h(66 gpm)and the VNX-MINI 12 m³/h(52.8 gpm),achieving>17 MΩ·cm resistivity at up to 95%recovery.These modules serve power generation boiler feedwater,semiconductor rinse water,and pharmaceutical purified water systems.
What Is a CEDI Module?
A CEDI(Continuous Electrodeionization)module is a water purification device that combines ion exchange resins,ion-selective membranes,and a DC electric field to continuously remove ionized and ionizable species from water without chemical regeneration.It replaces conventional mixed-bed deionizers,eliminating the need for acid and caustic handling while producing high-resistivity water directly from reverse osmosis permeate.
The IONPURE VNX platform represents large-flow CEDI technology,with VNX-MAX and VNX-MINI modules scaling the proven stack-and-frame design to single-module flows suitable for high-capacity industrial systems.They transform RO permeate into ultrapure water(typically>17 MΩ·cm)for applications demanding low total organic carbon(TOC),low silica,and consistent water quality.

Technical Highlights
Single-module high flow minimizes system footprint and capital cost.The VNX-MAX delivers 15 m³/h from one module,reducing the number of parallel modules and associated piping compared to traditional CEDI stacks.The VNX-MINI’s compact 168 cm height achieves 12 m³/h,further shrinking skid dimensions in space-constrained facilities.
Flexmount end-connector system enables tool-free stacking and hydraulic linking.Modules connect directly without intermediate piping manifolds,cutting installation time and leak points while maintaining alignment.This design feature directly addresses the question"How do I connect multiple VNX modules hydraulically?"—the answer is built into the stack.
Integrated terminal box simplifies field wiring.The on-board wiring enclosure accepts power and signal cables directly at the module,eliminating the need for separate junction boxes and reducing commissioning labor.
Wide hardness tolerance reduces RO pre-treatment burden.With a feed water hardness specification of≤1.0 ppm as CaCO₃,the VNX modules accept RO permeate from softening-free systems in many municipal water sources,provided silica and CO₂are controlled.
Applications
High-pressure boiler feedwater polishing:Produces ultrapure makeup water for subcritical and supercritical boilers in power plants.The>17 MΩ·cm resistivity and low silica specification meet stringent turbine manufacturer requirements,directly extending steam cycle life and reducing blowdown frequency.
Semiconductor and microelectronics rinse water:Generates deionized water with consistent resistivity and low TOC for wafer cleaning and etching processes.The 95%recovery rate reduces overall facility water consumption,a critical metric in fabs facing water scarcity constraints.
Pharmaceutical purified water(PW)and water for injection(WFI)pretreatment:Serves as the final polishing step post-RO to reliably meet USP and EP conductivity standards for Purified Water without chemical regenerants.Validation support documentation is available through the manufacturer.
Chemical and petrochemical process water:Delivers high-purity water for catalyst makeup,process dilution,and steam generation in refineries and chemical plants.The module’s corrosion-resistant PVC construction and chemical-free operation align with facilities targeting reduced hazardous material handling.
Large-scale industrial demineralized water systems:Replaces conventional mixed-bed ion exchange in central utility plants supplying factories with 10–100 m³/h deionized water demand.The modular Flexmount design allows phased capacity expansion without major piping rework.
Selection Guidance
Suitable applications:
Systems requiring a single CEDI module with flow between 10 and 20 m³/h(44–88 gpm)
Replacement or upgrade of aging mixed-bed demineralizers to eliminate acid/caustic handling and neutralization waste
New-build power,semiconductor,or pharmaceutical water systems with indoor space for vertical module installation(minimum ceiling height 2.2 m for VNX-MAX)
Projects utilizing the IONPURE DC3+rectifier(IP-DC3PH600V-M1),which is fully compatible and eliminates the need for an isolation transformer
Not recommended for:
Feed water with hardness consistently exceeding 1.0 ppm as CaCO₃.Install a softener upstream or select a CEDI module rated for higher hardness tolerance.
Outdoor installation without weather protection.These modules carry an IP rating suitable for indoor use only;protect from direct sunlight and precipitation.
Applications requiring intrinsic pharmaceutical validatability(e.g.,direct WFI generation without distillation).For hot-sanitizable CEDI,consult alternative IONPURE products.
Flows above 22.7 m³/h from a single module.Parallel multiple VNX-MAX modules using the Flexmount system;system design is simplified compared to older multi-stack approaches.
