IONPURE MX Small Flow CEDI Module for RO EDI Water System and Compact Ultrapure Water System

　　IONPURE MX Series is a compact ultrapure water system integrating RO EDI water system technology for laboratory and small-demand applications.Nominal flow spans 30–500 L/h,delivering>16 MΩ·cm product water without chemical regeneration.Designed for analytical labs,general electronics,and food and beverage processing,it achieves 90–95%water recovery and continuous,stable resistivity.

　　What Is an RO EDI Water System?

　　An RO EDI water system combines reverse osmosis pretreatment with continuous electrodeionization polishing to produce high-purity water without periodic chemical regeneration.RO removes dissolved solids and organics,while the CEDI module strips residual ionizable contaminants using electric potential,ion-exchange membranes,and mixed-bed resin—delivering pure water continuously.

　　A compact ultrapure water system scales this technology down to laboratory and small process flows,typically 30 to 500 liters per hour.The Ionpure MX series exemplifies this category,offering plug-and-play CEDI modules designed for point-of-use polishing or small central loops where traditional mixed-bed cylinders and acid/caustic handling are impractical.

　　Technical Highlights

　　No acid,caustic,or chemical injection.The MX module continuously self-regenerates using DC voltage alone,removing the complexity,cost,and safety risk of regeneration chemicals.A common question—whether inline chemical dosing is required—is answered by the All-Fill concentrate compartment:the module operates without brine injection,preserving a compact footprint.

　　Double O-ring sealing ensures zero external leakage.Each cell stack is sealed with dual O-rings and a robust housing,permitting continuous operation at 5 bar and 45°C without seepage.This dry-exterior design protects nearby equipment and simplifies enclosure ventilation.

　　Variable production from 30 to 500 L/h with standard housings.Five model sizes share the same 17.78 cm height and mounting geometry,allowing users to select precisely the flow needed and upgrade capacity without redesigning the distribution loop.

　　High resistivity without batch cycling.The output resistivity holds>16 MΩ·cm with minimal fluctuation,unlike deionization bottles that decline toward exhaustion.This stability is essential for sensitive analytical instruments such as inductively coupled plasma mass spectrometers(ICP-MS)and ion chromatographs.

　　Applications

　　Analytical laboratory water polishing:Placed after a benchtop reverse osmosis unit,the MX module provides a continuous polish to>16 MΩ·cm Type I water for trace metal analysis,HPLC,and autoclave feed,eliminating multiple DI cartridge changes per week.

　　General electronics and small parts cleaning:Supplies high-purity rinse water for printed circuit board production and precision component cleaning,avoiding ionic residues that cause corrosion or short circuits.

　　Food and beverage quality testing:Laboratory-scale pure water for enzymatic analysis,sensory evaluation dilution,and cleaning of glassware,with Halal-certified materials meeting food-sector compliance requirements.

　　Pharmaceutical R&D and point-of-use purified water:Delivers compendial-compliant water for small-volume pilot batches,buffer preparation,and glasswasher feed without the chemical regeneration footprint of a central mixed-bed plant.

　　Clinical analyzer and steam sterilizer feed:Maintains ultra-low conductivity for automated chemistry analyzers and autoclaves,reducing maintenance cycles and preventing mineral scaling on heating elements.

　　Selection Guidance

　　Suitable for:

　　Point-of-use polishing for a single laboratory building,instrument room,or small production line requiring 30–500 L/h

　　Sites where chemical handling restrictions prohibit acid/caustic regeneration,such as mobile labs,cleanrooms,or food facilities

　　RO permeate feed with conductivity consistently below 40µS/cm and silica<1.0 ppm,typical of a single-pass RO with softening or anti-scalant

　　Systems needing unattended continuous flow—the MX maintains steady resistivity without operator intervention

　　Not suitable for:

　　Feed water conductivity exceeding 40µS/cm or hardness>1.0 ppm.If source supply fluctuates,a double-pass RO or an upstream softener should be added to protect the module.An alternative is the Ionpure VNX-CDIT which tolerates higher inlet conductivity.

　　Flow demands above 500 L/h when using a single module.Multiple MX units can be paralleled,but for flows exceeding 2 m³/h a larger-frame module such as the Ionpure VNX30-EX or VNX55-EX offers lower capital cost per liter.

　　Applications requiring>18 MΩ·cm water with sub-ppb silica and boron levels,as in advanced semiconductor fabs.The MX series guarantees>16 MΩ·cm and is not specified for ultra-trace boron removal typical of microelectronics polishing.

　　FAQ

　　1.How much does an Ionpure MX CEDI module cost?

　　The MX module price ranges from 4,500to12,000 USD depending on the flow model(033 to 500 L/h)and distribution channel.Prices fluctuate due to exchange rates,tariffs,and factory adjustments.For an accurate quotation including freight,contact Beijing Zhongping Technology directly.

　　2.What is the delivery time for the MX module?Are they in stock?

　　Standard lead time is 6 to 8 weeks ex-works.Regional distributors often hold inventory of the most common models,which can ship within 1 to 2 weeks.

　　3.What payment terms are available for this purchase?

　　We accept wire transfer(T/T)in advance,letter of credit(L/C),and for approved accounts,net 30 days after delivery.Contact Beijing Zhongping Technology to discuss your preferred payment method.

　　4.Can I run the MX module with a single-pass RO system,or do I need double-pass RO?

　　Single-pass RO is sufficient if permeate conductivity stays below 40µS/cm and silica<1.0 ppm.We recommend an online conductivity meter with alarm to ensure feed quality stays within spec to protect the module.

　　5.What is the difference between the IP-MXM030 and IP-MXM500 models?How do I choose?

　　The five models differ only in production flow capacity:30,60,125,250,or 500 liters per hour.Choose the model that matches your peak purified water demand;oversizing by more than 20%is unnecessary.For example,a lab consuming 100 L/day intermittently can use the MXM030,while a continuous small-part washer may require the MXM250.

　　6.Does the MX module require any consumables or maintenance?

　　No acid,caustic,or replacement resin cartridges are needed.Maintenance is limited to annual inspection of seals and electrical connections.The module has no consumable parts for the first 5–7 years of operation under normal conditions.

　　7.What warranty do you provide with the MX CEDI module?

　　We provide a 2-year limited warranty against material and workmanship defects.Extended warranty for up to 5 years is available for purchase.Performance under warranty requires adherence to feed water specs and operating conditions.

　　8.Can I install the MX module myself,or is professional commissioning required?

　　The module is supplied with a connection kit and installation manual,and qualified plant staff can complete the plumbing and wiring.Commissioning assistance from Beijing Zhongping Technology includes remote setup verification and is recommended for first-time CEDI users to ensure correct polarity and flow distribution.

　　9.What happens if feed water quality temporarily goes out of spec—will the module be damaged?

　　Short-term excursions(minutes to hours)above 40µS/cm conductivity or hardness will not cause permanent damage,but extended operation outside spec reduces resin lifetime and may require factory regeneration.An automatic divert valve on the product outlet is the standard protection method.

　　10.What pretreatment do I need before the RO feeding the MX module?

　　At minimum,a reverse osmosis system with a UV dechlorination unit(free chlorine<0.02 ppm)and a 5-micron pre-filter.If feed hardness exceeds 1.0 ppm as CaCO₃,add a water softener.For silty or high-SDI surface water,a multimedia filter and activated carbon pre-filtration are recommended.
