TEYU Wins OFweek 2026 Technology Innovation Award for Advanced UV Laser Chiller Solution

UV lasers are widely used for applications such as PCB microvia drilling, wafer dicing, and precision marking, where processing accuracy and consistency are important. While the laser source gets most of the attention, its cooling system also plays an important role. Keeping the laser at a stable operating temperature can help maintain consistent performance during continuous operation.

This is one reason precision temperature control matters in UV laser cooling. A chiller is not simply there to remove heat; it needs to maintain the required temperature and respond to changes in the system.

A Compact Chiller for UV Laser Systems
TEYU’s CWUP-05THS is designed for UV laser systems that require precise temperature control in a compact package. It provides ±0.1°C temperature stability and uses PID temperature compensation to adjust cooling performance as operating conditions change.
The chiller also supports Modbus communication, allowing it to connect with the control and monitoring systems of laser equipment. Its compact design can be useful when installation space is limited.
These features recently helped the CWUP-05THS receive the Technology Innovation Award for Laser Equipment Supporting Products at the OFweek 2026 Laser Industry Annual Awards. The award was based on expert evaluation and public voting.

Why Does Chiller Selection Matter?
For a UV laser system, choosing a chiller based only on cooling capacity may not be enough. Temperature stability, cooling range, heat load, ambient conditions, communication interfaces, and available installation space can all affect whether a cooling system is suitable for the application.
The right cooling solution should therefore be matched to the laser source and the actual operating conditions of the equipment.
For TEYU, the CWUP-05THS award is also a reflection of its continued focus on industrial temperature control. Founded in 2002, TEYU has more than 700 employees, 66 authorized patents, and customers in over 100 countries and regions. Its chillers are used across laser processing, additive manufacturing, CNC machining, and other industrial applications. In 2025, the company shipped more than 230,000 units.
Ultimately, a laser chiller is only one part of a complete laser system, but stable thermal management can make a meaningful difference to equipment operation. For UV laser applications where temperature stability and integration are important, a compact precision chiller such as the CWUP-05THS is one option worth considering.

How Does a Fiber Laser Chiller Work? Here's What Actually Happens Inside

When people think about a fiber laser chiller, they often imagine it simply pumping cold water through a laser machine.

In reality, that's only part of the process. A fiber laser chiller doesn't just circulate water—it continuously collects heat, transfers it, and releases it to the surrounding air through a closed-loop refrigeration system. Understanding how this works helps explain why industrial chillers are essential for modern high-power laser cutting, welding, and cleaning systems.

Step 1: The Chiller Absorbs Heat from the Laser
A fiber laser generates heat not only from the laser source itself but also from optical components that guide and shape the beam.
That's why many industrial fiber laser chillers, including the TEYU CWFL Series, use dual independent water circuits: One circuit cools the laser source. The other cools the optics.
By separating these cooling loops, each part of the laser system receives the temperature control it requires, helping maintain stable laser output and beam quality during continuous operation.

Step 2: The Heat Is Transferred to the Refrigeration System
Once the cooling water absorbs heat from the laser, it returns to the chiller.
Instead of being cooled directly by the refrigerant, the water first passes through a plate heat exchanger. Here, heat moves from the water to the refrigerant while the two fluids remain completely separate.
This design improves heat transfer efficiency and helps keep the cooling water clean, making it well suited for long-term industrial operation.

Step 3: The Refrigeration System Releases the Heat
The refrigerant then circulates through a standard vapor-compression refrigeration cycle:
Compressors increase refrigerant pressure.
Condensers, assisted by cooling fans, release heat into the surrounding air.
Expansion (throttling) devices lower refrigerant pressure and temperature.
The cooled refrigerant returns to the heat exchanger to absorb heat again.
This continuous cycle allows the chiller to remove heat from the laser system rather than simply recirculating warm water.

Why Dual Cooling Circuits Matter
As fiber laser power increases—from a few kilowatts to 20kW, 40kW, or even higher—thermal management becomes increasingly important.
Using separate cooling circuits offers several advantages:
* More stable operating temperatures
* Better protection for the laser source and optics
* Improved processing consistency
* Reduced thermal stress during long production runs
For high-power laser equipment, cooling is no longer just an accessory—it is an integral part of overall system performance.

Final Thoughts
A fiber laser chiller is much more than a water pump. It combines independent water circulation with a closed-loop refrigeration system to remove heat continuously and maintain stable operating temperatures.
Whether you're selecting a chiller for a new laser machine or simply want to understand how these systems work, knowing the cooling principle makes it easier to appreciate the role thermal management plays in laser performance, reliability, and equipment longevity.
Manufacturers such as TEYU offer standardized fiber laser chillers covering applications from 1kW to 240kW, designed to provide stable temperature control for a wide range of industrial laser systems.
