LCX-45H High-Temperature China EDI stacks High-Flow Ultra-Pure Water Solution for Large Factories
Recently, many clients from large-scale electronics factories, chemical plants, and photovoltaic component workshops have asked: "Which EDI stacks can handle 5m³/h water demand while enduring frequent high-temperature disinfection?" Today I’ll focus on the LCX-45H—this high-temperature China EDI stacks is a "workhorse" for large water consumption scenarios, solving the "unstable water quality + high maintenance cost" problem for many factories.
Let me share a story from a client that makes semiconductor wafers. They used to run three small EDI units in parallel to meet their 5m³/h ultra-pure water needs. But every time they did 85℃ high-temperature disinfection (required for wafer cleaning), at least one unit would fail—either the produced water resistivity dropped below 9MΩ·CM (failing to meet the 10MΩ·CM standard) or the membrane stack leaked. They had to stop production for repairs every 45 days, costing over 100,000 yuan in losses each time.
Then they switched to the LCX-45H China EDI stacks. For 20 months now, it’s run continuously at 56℃ inlet water temperature, with 145+ high-temperature disinfections. The produced water resistivity has stayed steady at 13-18MΩ·CM, and there’s been zero unplanned downtime. The factory’s water treatment supervisor said: "This one unit replaces three old ones, saves 40% of the equipment area, and cuts annual maintenance costs by 50%—this China EDI stacks is exactly what we needed for large-scale production."
What makes it so reliable? It’s tailor-made for high-flow, high-temperature scenarios: 4.8-5.3m³/h water output, 60℃ maximum inlet water tolerance, and 85℃ disinfection resistance—perfect for factories where "high flow + stable quality" is non-negotiable.
Choosing EDI stacks is all about "matching parameters to on-site needs." I’ve sorted the high-temperature inlet water requirements and operating parameters of LCX-45H into clear tables—you can print this for your on-site team to reference!
| Item | Requirement | Key Reminder |
|---|
| Water Source | Reverse Osmosis (RO) Product Water | Non-RO water will damage the ion exchange resin in 2-3 months |
| Inlet Conductivity | ≤10μs/cm (including CO₂ & Si) | Keep it ≤5μs/cm—this extends membrane life by 2-3 years |
| Temperature | 5-60℃ | The system shuts down automatically if over 60℃ to protect the membrane stack |
| Inlet Pressure | 0.1-0.3MPa | Unstable pressure reduces ion removal efficiency by up to 25% |
| Total Chlorine (Cl₂) | ＜0.02ppm | Chlorine oxidizes resin—even 0.03ppm causes resin discoloration and efficiency loss |
| Iron (Fe)/Manganese (Mn) | ＜0.01ppm each | Excess forms brown precipitates that block membrane pores |
| Sulfide (S²⁻) | ＜0.01ppm | Reacts with resin to form sticky substances, slowing water flow |
| pH Value | 7-8 | pH below 7 or above 8 slows desalination by 15-20% |
| Total Hardness (as CaCO₃) | ＜0.5ppm | Prevents white scale buildup in fresh water chambers |
| TOC (Organic Matter) | ＜0.5ppm (as C) | Organic matter clogs membranes—long-term excess causes irreversible damage |
| Silicon (as SiO₂) | ＜0.5ppm | Silicon precipitates at high temperatures, making produced water "cloudy" |
| Oxidizers/Oil/Fat | Not Detected | Even a tiny drop of oil breaks the membrane structure, rendering it useless |
| Item | Parameter | Practical Tip |
|---|
| Flow Range | 4.8-5.3m³/h | Don’t go below 4.8m³/h—low flow causes resin "idleness" and reduces service life |
| Operating Current | 2.5A (0-6A adjustable) | Stable current ensures consistent water quality (no sudden resistivity drops) |
| Operating Voltage | 0-550VDC | Auto-adapts to inlet water quality—no manual adjustment needed |
| Maximum Power | 3KW/H | 13% more energy-efficient than similar high-flow EDI stacks |
| Recovery Rate | 85-95% | Reuse concentrated water as RO inlet—saves 30% water annually |
| Max Inlet Temp | 60℃ | Safe for 24/7 continuous operation |
| Disinfection Temp | 85℃ | ≥150 disinfections without membrane replacement |
| Produced Water Resistivity | ≥10MΩ·CM | Typically 12-18MΩ·CM in real use (meets electronic/chemical industry standards) |
| Dimensions (H×W×L) | 605mm×315mm×945mm | Fits in most factory equipment areas—no need for extra expansion |
| Connections | Fresh water: 1-1/4″ PT internal thread; Concentrated water: 3/4″ PT internal thread | Matches common industrial pipes—installation takes 2-3 hours |
Many clients say "large EDI stacks are hard to maintain," but it’s just about daily small checks. For this LCX-45H China EDI stacks, your on-site technician can do these in 15 minutes a day:
Daily Pressure & Flow Check: Use the pressure gauge to ensure fresh water inlet/outlet pressure is 0.15MPa higher than concentrated water’s. If the flowmeter shows below 4.8m³/h, adjust the control valve immediately—don’t let it run "underloaded."
Water Quality Monitoring: Check inlet water conductivity every morning (only pass if ≤5μs/cm) and produced water resistivity every afternoon (shut down if <10MΩ·CM). If values are off, fix the RO system first—bad RO water is the No.1 killer of EDI stacks.
Post-Disinfection Inspection: After 85℃ disinfection, let the system cool to <50℃ before restarting. Wipe the anode/cathode junction boxes with a dry cloth (prevents short circuits) and check the membrane stack for leaks—small issues fixed early save tens of thousands in repair costs.
Concentrated Water Reuse Trick: Don’t drain concentrated water! Send it back to the RO tank, but add a 5μm filter first—this stops tiny impurities from clogging the EDI membrane (we’ve seen this extend membrane life by 1 year).
Q1: Can the LCX-45H China EDI stacks be used with a 2-stage RO system?
A1: Absolutely! A 2-stage RO system’s produced water (usually conductivity ≤3μs/cm) is perfect for LCX-45H. We helped a chemical plant pair them last year—their produced water resistivity has stayed at 15-18MΩ·CM, fully meeting the requirements for reactor cooling water.
Q2: What if the inlet water temp suddenly jumps to 62℃? Will the EDI be damaged?
A2: No, it has a safety protection function! The LCX-45H automatically shuts down when inlet temp exceeds 60℃. Just cool the RO produced water to 55-60℃, reset the system, and it will work normally again—no damage to the membrane stack.
Q3: How fast is after-sales support if something goes wrong?
A3: Super fast! Call +86-13646187144 or email [email protected]—engineers usually reply within 1 hour. A client once had a pressure alarm at 11 PM; the team guided them to fix it via video call in 20 minutes, so production wasn’t affected.
Mr. Li (Large Chemical Plant Manager): "We use LCX-45H for reactor feed water—needs 5m³/h and high purity. This China EDI stacks runs 24/7, and the water resistivity never drops below 14MΩ·CM. Way better than the imported EDI we used before, and 35% cheaper!"
Ms. Wang (Photovoltaic Component Factory Supervisor): "Our solar panel cleaning line needs stable ultra-pure water. The LCX-45H handles 5m³/h easily, and high-temperature disinfection is a breeze—no more stopping production to replace small EDI units. This EDI stacks has become a key part of our production line."
