Ionpure MX Series CEDI Modules

Ionpure MX Series modules are low-flow continuous electrodeionization (CEDI) modules for laboratory and smaller-scale applications. Five models, MX30, MX60, MX125, MX250 and MX500, cover a nominal flow of 30 to 500 L/h, which suits single-module installations. As Ionpure’s OEM partner in Turkey, Mikron Proses (Üsküdar, Istanbul) supplies replacement MX30, MX60, MX125, MX250 and MX500 modules, matches them with a DCR power supply and provides application consulting on chemical cleaning (CIP) and maintenance.

The MX series sits below the LX and VNX families in flow. For an overview of all Ionpure CEDI modules, see EDI / CEDI systems; for higher-flow industrial needs see the Ionpure LX series and the Ionpure VNX series.

Ionpure MX models compared

Model	Nominal flow (L/h)	Flow range (L/h)	Max. FCE (µS/cm)	Silica (SiO₂) removal	DC requirement (manual IP-MAN-MX, Table 2-1)
MX30	30	15 – 45	≤ 40	90 – 99%	0 – 27 VDC · 0 – 2.5 A
MX60	60	30 – 90	≤ 40	90 – 99%	0 – 53 VDC · 0 – 2.5 A
MX125	125	62.5 – 187	≤ 40	90 – 99%	0 – 106 VDC · 0 – 2.5 A
MX250	250	125 – 375	≤ 40	90 – 99%	0 – 213 VDC · 0 – 2.5 A
MX500	500	250 – 750	≤ 40	90 – 99%	0 – 426 VDC · 0 – 2.5 A

Note: FCE is the feed conductivity equivalent, including CO2 and silica. The datasheet (ION-MXLowFlow-DS-0818) groups the power supply sizing by module length at a maximum of 200, 400 or 600 VDC (2.5 A DC), while the manual gives each model’s own maximum DC voltage (27 to 426 VDC). The actual DC requirement depends on the application and can be calculated with the manufacturer’s projection software.

MX30 to MX500: from laboratory to smaller-scale systems

The five models cover the nominal flow range in steps, from the MX30 (nominal 30 L/h, minimum 15 and maximum 45 L/h) to the MX500 (nominal 500 L/h, minimum 250 and maximum 750 L/h). All models share the same diameter of 17.78 cm; only the length changes, from 18.41 cm for the MX30 to 62.96 cm for the MX500. A double O-ring seal and housing give a leak-free design. The proprietary all-filled concentrate compartments remove the need for a separate recirculation pump or brine injection, which keeps single-module installations simple.

The modules run continuously at up to 5 bar feed pressure and up to 45 °C, with product water resistivity above 16 MΩ·cm and silica removal of 90-99%, depending on the feed water. Recovery is up to 95%.

Electrical supply and power supply selection

Each MX module needs up to 2.5 A DC at 27 to 426 VDC, depending on the model (200, 400 or 600 VDC maximum in the datasheet grouping). The DCR power supply offers a selectable 0-2.5 A current range, and the G4 power controller offers the same range, which matches the MX requirement; both are designed for use with MX, LX and VNX modules. See Ionpure DC3, DCR and G4 power supplies.

Installation and feed water requirements

MX modules should be installed indoors, out of direct sunlight, at an ambient temperature of no more than 45 °C. The feed water must be RO permeate with a conductivity equivalent (including CO2 and silica) below 40 µS/cm, a pH of 4-11 and a total hardness below 1.0 ppm (as CaCO3). The modules are CE marked and manufactured in an ISO 9001 and ISO 14000 quality and environmental management system.
