Ionpure CEDI (EDI) Modules and Power Supplies — Continuous Deionization
Ionpure VNX, LX and MX series CEDI (EDI) modules and DC3, DCR and G4 power supplies for chemical-free, continuous deionization, lab to industrial scale.
EDI (electrodeionization) removes the ions that remain in water after reverse osmosis using resin, ion-selective membranes and a continuous electric current. Because the resin regenerates itself with the current, no acid or caustic regeneration is needed and production does not stop. In purified water (PW) lines the typical chain is RO + EDI + UV + UF; in ultrapure water, 185 nm UV, polishing and final filtration are added.
Ionpure CEDI modules are used in power generation and boiler feed water, microelectronics, pharmaceutical and biotechnology, food and beverage, general industrial and laboratory applications. Mikron Proses includes Ionpure CEDI modules in the RO + EDI water treatment systems it designs, and selects the module and power supply together with you from the RO permeate quality, the target water class and the flow rate.
Module selection by flow rate
Values are taken from Ionpure datasheets.
| Series | Flow rate | Notable | Typical application |
|---|---|---|---|
| MX (MX30-MX500) | 30-500 l/h | 75 psi (5 bar), up to 45 °C; 90-95% recovery, 90-99% silica removal | Laboratory, small-scale RO systems |
| LX-Z / LX-X | LX-Z 0.22-10 m³/h, LX-X 0.22-7.67 m³/h | Plate-and-frame construction | Power, general electronics, food and beverage, laboratory |
| LX-HI | 0.22-7.67 m³/h | 85 °C hot water sanitization (about 1.5 hours); cGMP, USP, Ph. Eur. compatible | Pharmaceutical, biotechnology, medical |
| VNX (VNX-Max / Mini / Ultra) | Up to 22.7 m³/h (single module) | Silica and boron removal above 95% for VNX-Max/Mini, at least 99.8% for VNX-Ultra | Power generation, boiler feed water, microelectronics |
Power supplies
EDI modules run on a DC power supply. The Ionpure DC3 is a three-phase switch-mode supply with 0-600 VDC / 0-15 A output and MODBUS TCP-Ethernet. The DCR is a single-phase DC rectifier with 5 selectable current ranges. The G4 is a new-generation single-phase DC controller with electrical resistance logging and a cleaning alert.

Frequently Asked Questions about Ionpure
Common questions about Ionpure products and Mikron Proses services.
What is EDI (electrodeionization)?
EDI is a purification technology that continuously removes ions from water by using ion exchange resin and ion-selective membranes together with an electric current. The resin regenerates itself with the continuous electric current, so no chemical regeneration with acid and caustic is needed and production is uninterrupted. CEDI (continuous electrodeionization) is another name for the same technology.
What is the difference between EDI and resin-based deionization?
Resin-based systems have a low investment cost but require periodic chemical regeneration. EDI regenerates with a continuous electric current; it eliminates chemical use, provides uninterrupted production and lowers operating cost. EDI is recommended for pharmaceutical and high-purity applications.
What is needed before EDI?
The EDI module is fed with reverse osmosis (RO) permeate; the typical chain in purified water lines is RO + EDI + UV + UF.
Which Ionpure EDI module should be selected?
By flow rate: the MX series for laboratory and small systems (30-500 l/h), LX-Z (0.22-10 m³/h) and LX-X (0.22-7.67 m³/h) for medium volumes, and VNX (up to 22.7 m³/h) for high volumes. If hot water sanitization is required in pharmaceuticals and biotechnology, LX-HI (85 °C).
Can an EDI module be sanitized with hot water?
Yes. LX-HI modules are sanitized with 85 °C hot water; the duration is about 1.5 hours (about 3 hours for staged HWS modules). They are intended for applications that require microbial control in pharmaceuticals, biotechnology and food and beverage.
How is an EDI module powered?
The EDI module runs on a DC power supply. The Ionpure DC3 is three-phase with 0-600 VDC / 0-15 A output and MODBUS TCP-Ethernet; the DCR is single-phase with 5 selectable current ranges; the G4 is a new-generation single-phase controller with electrical resistance logging and a cleaning alert.
