LCX-10H High-Temperature Disinfection Type China EDI stacks The First Choice for High-Temperature Ultrapure Water Preparation in Small and Medium-Capacity Scenarios

Recently, many friends in food processing and pharmaceutical intermediate production have been asking which EDI stacks are suitable for temperature-resistant needs in small and medium-capacity scenarios. Today, I must recommend the LCX-10H – this high-temperature disinfection type China EDI stacks from LC PURE. It can stably produce water at 5-60℃ and even withstand high-temperature disinfection at 85℃, making it extremely popular in small and medium-sized factories that require frequent sterilization. There’s no need to worry about the impact of temperature on the equipment at all.

I. Core Parameters of LCX-10H China EDI stacks: Accurate Matching for High-Temperature Scenarios with Small and Medium Capacity

When choosing high-temperature China EDI stacks, it’s essential to understand the parameters thoroughly, especially temperature resistance and water production capacity. I’ve organized the key parameters of the LCX-10H into a table, so you can easily check against your own needs:

High-Temperature EDI Inlet Water Quality Requirements

As a high-temperature-specific China EDI stacks, the LCX-10H has clear requirements for inlet water. Only when these requirements are met can the equipment’s service life and water production effect be guaranteed – never overlook this:

• Inlet Water Source: Must be reverse osmosis (RO) product water (substandard pretreatment will directly damage the membrane stack)

• Inlet Conductivity: ≤10μS/cm; ≤5μS/cm when containing CO₂ and silicon (the lower the conductivity, the smaller the membrane stack loss)

• Temperature Range: 5-60℃ (can reach 85℃ for a short time during disinfection, but cannot exceed 60℃ for long-term operation)

• Inlet Water Pressure: 0.1-0.3MPa (unstable pressure will cause uneven water flow distribution)

• Total Chlorine Content (Cl₂): ＜0.02ppm (chlorine oxidizes ion exchange resins and must be completely removed)

• Heavy Metals (Fe/Mn/S⁻): All ＜0.01ppm (prone to forming precipitates and clogging membrane pores at high temperatures)

• pH Value: 7-8 (neutral range to avoid equipment corrosion or silicon precipitation)

• Total Hardness (as CaCO₃): ＜0.5ppm (high hardness leads to scaling at high temperatures, affecting desalination efficiency)

• Total Organic Carbon (TOC): ＜0.5ppm (calculated as C, to prevent resin contamination from high-temperature decomposition)

• Silicon Content (as SiO₂): ＜0.5ppm (silicon is a "key area" for high-temperature scaling and must be strictly controlled)

• Oxidizing Substances/Oil/Fat: Not detected (oxidizing substances damage resins; oil/fat clogs membrane pores, directly causing equipment failure)

High-Temperature EDI Operating Parameters

After the inlet water meets the standards, setting operating parameters reasonably is essential to maximize the performance of the LCX-10H China EDI stacks. Remember these standards:

• Recovery Rate: 85-95% (it is recommended to control it at around 90%; concentrated water can be recycled to the RO inlet water tank for reuse without wasting water)

• Maximum Inlet Water Pressure: ≤0.5MPa (maintain 0.2-0.3MPa during daily operation; open the pressure relief valve when exceeding 0.4MPa)

• Pressure Drop at Normal Flow: 0.1-0.3MPa (abnormal pressure drop may indicate a clogged pipeline and requires timely inspection)

• Maximum Inlet Water Temperature: 60℃ (cannot exceed this for continuous operation; reduce the flow slightly when raising the temperature for a short time)

• Disinfection Temperature/Frequency: 85℃ (single disinfection), ≥150 times (disinfect 2-3 times a month, sufficient for the equipment’s warranty period)

• Maximum Inlet Conductivity: ≤5μS/cm (the system will automatically alarm and shut down if exceeded during operation; do not force startup)

• Minimum Product Water Quality: ≥10MΩ·CM (check the inlet water or membrane stack status if it is lower than this value)

II. Practical Case of LCX-10H EDI stacks: No More Worries About High-Temperature Disinfection in Food Factories

Let me share a real case. A food factory in Jiangsu that produces fruit juice concentrates previously used ordinary EDI stacks to treat high-temperature cleaning water, but encountered many problems: water production became unstable when the temperature exceeded 35℃; the equipment had to be disassembled for manual disinfection every month, which was time-consuming and prone to contamination; and the wastewater treatment cost was high.

After switching to the LCX-10H China EDI stacks, the changes were particularly obvious:

1. It can stably produce water at 5-60℃, so the fruit juice production line no longer needs to shut down due to water temperature fluctuations, increasing production efficiency by 12%;

2. High-temperature disinfection at 85℃ can be performed directly, with 3 disinfections per month without disassembling the equipment. This saves 2 maintenance working hours and avoids the risk of manual contamination;

3. Concentrated water is recycled to the RO system, increasing the water resource utilization rate from 72% to 91% and saving over 6,000 yuan in monthly wastewater treatment costs.

The factory director told me: "If I had known that high-temperature China EDI stacks are so worry-free, I wouldn’t have struggled with ordinary equipment before. It was both costly and affected production!"

III. Maintenance Tips for LCX-10H EDI stacks: Easy Maintenance Even Under High-Temperature Conditions

Many friends are worried that EDI stacks are difficult to maintain under high-temperature conditions. In fact, the LCX-10H is very easy to maintain. Just remember these 5 small tips, and even beginners can handle it:

1. Keep an Eye on Inlet Water Quality: Before starting the machine each time, check the inlet water temperature (do not exceed 60℃) and conductivity (≤5μS/cm). If the standards are exceeded, treat the RO product water first to prevent unqualified water from entering the membrane stack;

2. Standardize Disinfection Operations: During disinfection at 85℃, first reduce the flow to 0.6m³/h. After disinfection, slowly cool down to below 60℃ before restoring the normal flow to avoid damaging the membrane due to excessive temperature difference;

3. Regularly Check Pressure and Flow: Check the pressure gauge (the pressure at the fresh water inlet and outlet should be 0.15MPa higher than that at the concentrated water inlet and outlet) and flowmeter (maintain 0.8-1.2m³/h) every day. If the values are incorrect, adjust the control valve – it only takes a few minutes;

4. Don’t Neglect Power Supply Maintenance: Be sure to use a DC power supply with "one-to-one control". Check the current (2.5A) and voltage (0-200VDC) every month, and do not let the power supply overload in high-temperature environments;

5. Inspect Connector Sealing: Threaded connectors are prone to loosening at high temperatures. Gently tighten the fresh water and concentrated water connectors with a wrench every month to ensure no liquid leakage and avoid safety hazards caused by high-temperature water leakage.

IV. Frequently Asked Questions About LCX-10H China EDI stacks

Q1: Our factory needs 1 ton of high-temperature purified water per hour. Can the LCX-10H meet this requirement?

Absolutely! Its flow range is 0.8-1.2m³/h, so 1 ton is right in the middle. Even if the short-term peak reaches 1.2 tons, it can handle it, and there’s no need to add additional equipment.

Q2: How much more expensive is the LCX-10H compared to ordinary EDI stacks? Is it worth buying?

The initial investment is slightly higher than that of ordinary models, but it’s more cost-effective in the long run: ordinary EDI requires frequent acid-base replacement and manual disinfection, with monthly maintenance costs of over 3,000 yuan; the LCX-10H does not require regeneration and saves trouble in disinfection, with monthly maintenance costs of only about 800 yuan. The price difference can be recovered in 3 months.

Q3: Do we need to modify the workshop pipelines to install the LCX-10H?

No major modifications are needed! Its fresh water interface is 1-1/4″PT female thread, and the concentrated water interface is 3/4″PT female thread, which can be directly connected to the high-temperature pipelines of most factories. Professional installers can complete the installation in one day without delaying production.

V. What Do Customers Say About LCX-10H China EDI stacks?

• Engineer Liu from a food processing factory in Shandong: "We use the LCX-10H to treat 45℃ cleaning water, and the product water quality is stably maintained at 11MΩ·CM. High-temperature disinfection at 85℃ is very convenient without disassembling the equipment. China EDI stacks are much more reliable than ordinary high-temperature equipment!"

• Manager Wang from a pharmaceutical factory in Zhejiang: "Previously, ordinary EDI had problems at 38℃.
