TEYU Chiller, S&a Chiller's Industrial Chiller Systems

4 months ago, we received a call from a Korea client Mr. Mahn.


Mr. Mahn: Hello. I am from Korea and I just purchased 20 units of metal fiber laser welding machines from Japan. These metal fiber laser welding machines are all powered by 1500W fiber laser source. However, the machine supplier didn't sell the water cooling machines with them. I found you online and thought maybe your water cooling machines might suit. Can you provide a cooling proposal? Here are the parameters of my metal fiber laser welding machines.



S&A Teyu: Well, according to the parameters you provide, we recommend you our water cooling chiller CWFL-1500. It is suitable for cooling 1500W fiber laser source and what's more, it is very versatile, for it can cool the fiber laser source and the QBH connector/optics at the same time, which is cost & space saving. In addition, water cooling machine CWFL-1500 is characterized by ±0.5℃ temperature stability, showing excellent temperature control. Last but not least, water cooling machine CWFL-1500 is loaded with eco-friendly refrigerant and with the approval from CE, ROHS, REACH and ISO, so there is no pollution during its operation.



Mr. Mahn: That sounds good. But since this is the first time I contact you, I would like to see water cooling machine in person first. I know you have a service point in Korea and I will make my decision after checking the water cooling machine at the service point.



S&A Teyu: Sure. Our water cooling machine won't let you down.



Two days later, he made a purchasing order of 20 units of water cooling machines CWFL-1500 in this first purchase! And one month after he had used the chillers, he said,”Your water cooling machines are doing the cooling job so well!” We thanked him for his trust and we will keep doing our best to maintain the good product quality.

The liquid inside the water pressure gauge of S&A Teyu closed loop chiller CW-6000 is oil. In normal cases, the oil inside the water pressure gauge is more than half of the volume of the water pressure gauge. If the oil level is too low, that means oil leakage possibly happens, which will lead to incorrect reading of the water pressure gauge. In this case, users need to replace with a new water pressure gauge.





After 18-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization. With cooling capacity ranging from 0.6KW to 30KW, our water chillers are applicable to cool different laser sources,laser processing machines, CNC machines, medical instruments, laboratory equipment and so on.

In industrial cooling systems, water quality maintenance plays a vital role in ensuring stable and efficient operation. Clean cooling water not only extends the service life of equipment but also enhances productivity and reduces maintenance costs. As extended holidays approach, such as National Day, planning proper industrial chiller water maintenance becomes even more important to prevent downtime issues when production resumes.



Why Regular Water Replacement Matters


1. Protecting the Laser Source
For laser equipment, stable temperature control directly affects production quality. Poor water quality reduces heat transfer efficiency, causing the laser source to overheat, lose power, and even become damaged. Regularly replacing cooling water helps maintain proper flow and efficient heat dissipation, keeping the laser operating at peak performance.



2. Ensuring Accurate Flow Sensor Performance
Contaminated water often carries impurities and microorganisms that can accumulate on flow sensors, disrupting accurate readings and triggering system faults. Fresh, clean water keeps sensors sensitive and reliable, ensuring consistent chiller performance and effective temperature regulation.







Recommended Water Maintenance Before Long Holidays


1. Replace Cooling Water in Advance
If your equipment will be idle for 3–5 days, it's best to replace the cooling water beforehand. Fresh water minimizes bacterial growth, scale buildup, and pipe blockages. When replacing water, thoroughly clean the system's internal piping before refilling with new distilled or purified water.



2. Drain Water for Extended Shutdowns
If your system will be idle for more than a week, drain all water before shutdown. This prevents stagnant water from fostering microbial growth or clogging pipes. Make sure the entire system is fully emptied to maintain a clean internal environment.



3. Refill and Inspect After the Holiday
Once operations resume, check the cooling system for leaks and refill it with distilled or purified water to restore optimal operation.






Daily Water Quality Maintenance Tips


Keep the Cooling Circuit Clean: Regularly flush the system to remove scale, impurities, and biofilm. Replace cooling water approximately every three months to maintain system hygiene and efficiency.



Use the Right Type of Water: Always use distilled or purified water. Avoid tap water and mineral water, which can accelerate scaling and microbial growth.


Maintaining proper water quality is one of the simplest yet most effective ways to protect your industrial chiller and laser equipment. By following these guidelines, especially before and after long holidays, you can extend equipment lifespan, stabilize cooling performance, and ensure your production runs smoothly year-round.
