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.

How to Manage Heat in Laser Systems and Electrical Cabinets?

Heat management is a critical factor in modern industrial manufacturing. For laser systems, automation equipment, and precision machinery, excessive heat can affect processing accuracy, equipment stability, and component lifetime.

However, heat does not come from only one source. Laser sources, optical components, power supplies, and electrical control systems all generate heat during operation. Effective thermal management requires different cooling approaches for different heat loads.

Two Major Thermal Challenges in Industrial Equipment

1. Cooling Laser Sources and Optical Components

High-power fiber and CO₂ lasers generate continuous heat during operation. Temperature fluctuations may affect:

* Laser output stability

* Beam quality

* Processing consistency

* Equipment reliability

Industrial laser chillers use closed-loop cooling to maintain stable temperatures and remove heat efficiently.

For example:

* CW Series is designed for CO₂ lasers, CNC machines, and general industrial processing equipment.

* CWFL Series features dual-circuit cooling for fiber lasers, with separate cooling circuits for the laser source and optical components.

* RMUP/CWUP Series provides compact and precision cooling solutions for UV lasers, ultrafast lasers, and laboratory applications.

2. Managing Heat Inside Electrical Cabinets

Electrical cabinets contain sensitive components such as PLCs, servo drives, and power modules. In enclosed environments, heat can quickly accumulate and reduce component reliability.

Unlike laser cooling, electrical cabinet cooling focuses on maintaining a stable internal cabinet environment.

TEYU provides:

* ECU Series industrial enclosure air conditioners for removing heat from electrical cabinets and control systems.

* CHE Series cabinet heat exchangers for energy-efficient heat transfer in applications with moderate heat loads.

Why Different Cooling Solutions Are Needed

A laser chiller and an electrical cabinet cooling system solve different thermal problems.

Laser chillers focus on:

* Precise temperature control

* Stable laser performance

* Consistent processing quality

Cabinet cooling solutions focus on:

* Protecting electronic components

* Preventing overheating

* Improving system uptime

Using the right cooling method for each heat source helps manufacturers improve production stability and reduce maintenance issues.

Applications of Industrial Thermal Management

TEYU industrial cooling solutions are widely used in:

* Laser cutting and welding

Why Does Your Industrial Chiller Keep Alarming in Summer?

Summer is one of the toughest seasons for industrial chillers. Higher ambient temperatures, increased production loads, dust buildup, and unstable power supplies can all make a chiller work harder than usual.

If your industrial chiller starts displaying frequent alarms during hot weather, don't assume it's a sign of equipment failure. In many cases, these alarms are built-in protection mechanisms that help prevent overheating and protect key refrigeration components.

Here are six common causes—and what you can do to reduce unnecessary alarms.

1. Make Sure the Chiller Has Enough Ventilation

Poor airflow is one of the most common reasons for summer overheating.

For most TEYU air-cooled chillers, the recommended installation clearance is:

* Low-power models: At least 1.5 m above the air outlet and 1 m around the air inlet.

* High-power models: At least 3.5 m above the air outlet and 1 m around the air inlet.

Adequate clearance prevents hot exhaust air from circulating back into the condenser, helping the chiller maintain stable cooling performance.

2. Check the Power Supply

Summer often brings heavier electrical loads, which can cause voltage fluctuations.

TEYU recommends keeping the supply voltage within ±5% of the rated input voltage. If power is unstable, using a properly sized voltage stabilizer can help prevent unnecessary alarms and improve compressor reliability.

3. Keep the Ambient Temperature Under Control

Even a properly functioning chiller has limits.

For most TEYU industrial chillers, the recommended ambient operating temperature is 20°C–30°C (68°F–86°F). If the surrounding temperature remains above 40°C (104°F), the chiller's high-temperature protection may be triggered.

Improving workshop ventilation or adding auxiliary cooling can help maintain stable operation during extreme heat.

4. Clean the Condenser Regularly

Dust buildup reduces airflow and heat dissipation, forcing the refrigeration system to work harder.

Clean the condenser and air filter regularly using compressed air. In dusty workshops, more frequent cleaning is recommended to maintain cooling efficiency and reduce energy consumption.

5. Replace Cooling Water Periodically

Over time, circulating cooling water can become contaminated, reducing heat transfer efficiency and increasing the risk of corrosion.

TEYU recommends replacing the cooling water approximately every three months, using distilled or purified water, and cleaning the water tank during water replacement.

6. Inspect the Water Filter

A clogged filter can restrict water flow and reduce cooling performance.

Regularly clean the filter screen and replace the filter element according to the manufacturer's maintenance recommendations to keep the cooling system operating efficiently.

An Alarm Doesn't Always Mean Something Is Broken

Many users assume a high-temperature alarm indicates equipment failure. In reality, industrial chillers are designed to protect themselves when operating conditions become unfavorable.

Simple maintenance, such as ensuring proper ventilation, cleaning the condenser, maintaining stable power, and replacing cooling water regularly, can significantly reduce summer alarms and improve long-term reliability.

If alarms continue after routine maintenance, it's best to contact the equipment manufacturer or service team for further troubleshooting.

Why this matters

Preventive maintenance takes far less time and cost than unexpected downtime. Spending a few minutes checking ventilation, water quality, and cleanliness can help your industrial chiller operate more reliably throughout the hottest months of the year.
