LC-4000 Industrial General-Purpose China EDI stacks A Complete Guide to Parameters Cases and Maintenance

Many friends engaged in industrial ultrapure water preparation have recently asked me which EDI stacks are suitable for medium and large-scale capacity scenarios. Today, I'd like to talk about the LC-4000 - this industrial general-purpose China EDI stacks from LC PURE, which is particularly popular in the electronics, chemical industry and vehicle urea purification industries, with excellent cost-effectiveness and stability.

I. Core Parameters of LC-4000 China EDI stacks: A Must-Have for Medium and Large-Scale Capacity Needs

When choosing EDI stacks, it is essential to have a clear understanding of the parameters. As an industrial general-purpose model, the LC-4000 has parameters that are fully suitable for the continuous water demand of medium and large-scale factories. I have organized the specific data into a table for your easy reference:

The advantage of this China EDI stacks is obvious: unlike traditional mixed beds that require frequent acid-base regeneration, it operates fully automatically and can stably produce water, making it very suitable for factories pursuing high efficiency and environmental protection.

II. Practical Application Case of LC-4000 EDI stacks: Cost-Saving and Stable Water Quality

Just talking about parameters is not enough. Let me share a real case with you. A factory in Shenzhen that manufactures semiconductor components previously used traditional mixed beds to produce ultrapure water, but encountered many problems: it had to shut down twice a week to replace acid and alkali, the monthly wastewater treatment cost was nearly 15,000 yuan, and the water quality fluctuated, occasionally affecting the chip cleaning quality.

Later, they switched to the LC-4000 China EDI stacks, and the changes were remarkable:

1. Regeneration was no longer needed, saving a total of 22,000 yuan per month on acid-base procurement and wastewater treatment costs;

2. With fully automatic control, no dedicated personnel were required to monitor it, allowing maintenance staff to focus on other tasks;

3. The product water quality was stable at 16-18MΩ·CM, with no water quality fluctuations in half a year, and the chip yield rate even increased by 2%.

The factory director told me later: "If I had known that China EDI stacks are so easy to use, I shouldn't have hesitated for so long!"

III. Maintenance Tips for LC-4000 EDI stacks: Simple and Easy to Operate, Prolonging Service Life

Many friends are worried that EDI stacks are troublesome to maintain. In fact, the LC-4000 is very easy to maintain. Just remember these 4 points, and even beginners can handle it:

1. Don't neglect daily monitoring: 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 (keep the flow at 3.8-5.2m³/h) every day. If the readings are incorrect, just adjust the control valve;

2. Regular water quality monitoring is necessary: Use a conductivity meter to check the inlet water (≤5μS/cm) and product water resistance (≥15MΩ·CM) every week. If the standards are exceeded, shut down the machine for inspection immediately and do not force operation to avoid damaging the membrane stack;

3. Pay attention to power supply maintenance: Be sure to use a DC power supply with "one-to-one control". Check the current (2.5A) and voltage (0-550VDC) every month. In case of an alarm, cut off the power first before repairing;

4. Don't waste recycled concentrated water: Concentrated water can be recycled back to the RO inlet water tank for reuse, which can also reduce emissions. In addition, the security filter for pretreatment should be cleaned regularly to prevent oil and oxidizing substances from entering - this is the key to protecting China EDI stacks!

IV. Frequently Asked Questions about LC-4000 China EDI stacks

Q1: My factory needs 4.5 tons of ultrapure water per hour. Is the LC-4000 sufficient?

Yes! Its maximum water production flow can reach 5.2m³/h, so 4.5 tons is within its capacity. Moreover, it can output stably even during peak water demand, so there's no need to worry about insufficient supply.

Q2: What are the advantages of the LC-4000 compared with other EDI stacks?

It has 38 membrane pairs, so its ion removal efficiency is higher than that of small-sized models, and its operating cost is low. With a power of 3KW/H, it saves about 500 kWh of electricity per month compared with other equipment of the same capacity. In addition, it does not require treatment of waste acid and alkali, complying with environmental protection policies.

Q3: Do I need to modify the workshop pipelines to install the LC-4000?

No major modifications are needed! Its fresh water interface is DN25 PVC and the concentrated water interface is DN20 PVC, which are compatible with the industrial pipelines of most factories. Professional installers can complete the installation in one day.

V. What Do Customers Say About LC-4000 China EDI stacks?

• Engineer Zhang from a vehicle urea purification plant in Dongguan: "We have been using the LC-4000 for nearly a year, and the product water quality is stable at 17MΩ·CM, meeting the urea purity standard. Moreover, after the concentrated water is recycled, the water resource utilization rate has increased from 70% to 90%. China EDI stacks are really reliable!"

• Manager Li from a chemical enterprise in Suzhou: "I was worried that EDI stacks would be expensive at first, but after calculating the account, I found that the cost can be recovered in 3 months. Now, the money saved every month can be used to buy 2 more sets of equipment. It's really worth it!"
