How Do Ultrafast and UV Laser Chillers Work?

To maintain the precision and reliability of ultrafast and UV laser systems, an efficient cooling solution is essential. TEYU CWUL & CWUP & RMUP series industrial chillers are specifically designed to meet this need. Each unit is equipped with a high-quality compressor, condenser, evaporator, throttling valve, water pump, and more, ensuring stable and accurate temperature control. But how exactly does the cooling process work? Let's break it down.

Closed-Loop Water Circulation System
At the heart of the chiller is a closed-loop water circulation system. The refrigeration system cools the circulating water, which is pumped to the laser equipment. As the laser operates, it generates heat that is absorbed by the water. The now-warm water returns to the chiller, where it is cooled again before being recirculated. This continuous cycle helps maintain optimal temperature, protects the laser components, and extends the system's lifespan.

Refrigerant Circulation System
The refrigerant circulation system plays a crucial role in heat exchange. Within the evaporator, the refrigerant absorbs heat from the returning water and evaporates into a low-pressure vapor. This vapor is then compressed by the compressor into a high-temperature, high-pressure gas. The gas flows into the condenser, where it releases heat and transforms into a high-pressure liquid with the aid of a fan. The liquid then passes through a throttling device, which lowers the pressure, allowing the refrigerant to re-enter the evaporator and repeat the cycle.

Precision Temperature Control for Laser Stability

Users can easily set and monitor the water temperature through a digital thermostat, ensuring precise control. This precision minimizes temperature fluctuations, preventing laser beam drift and reducing the risk of defects in laser processing. As a result, TEYU industrial chillers help maintain operational stability and improve product quality in high-precision laser applications.

Whether you are using ultrafast lasers for micromachining or UV lasers for fine marking, a reliable chiller solution is essential for performance and longevity. TEYU laser chillers are your trusted solution for consistent and efficient cooling.

How to Choose the Right Laser and Cooling Solution for Industrial Applications?

In industrial manufacturing, selecting the appropriate laser system, alongside a reliable cooling solution, is key to maximizing efficiency and maintaining equipment stability. Fiber lasers and CO₂ lasers are two of the most common types, each with unique advantages and cooling requirements.

Fiber lasers utilize solid-state fiber as the gain medium and are widely used for cutting metal due to their high electro-optical conversion efficiency (25–30%). They deliver fast cutting speeds, precise performance, and lower long-term maintenance needs. Though the initial investment is higher, fiber lasers are ideal for high-volume production environments that demand long-term reliability.

CO₂ lasers, which use gas as the gain medium, are versatile for cutting and engraving non-metallic materials such as wood, acrylic, glass, and ceramics, as well as some thin metals. Their lower upfront cost makes them suitable for small businesses and hobbyists. However, they require more frequent maintenance, such as gas refills and laser tube replacements, which may result in higher ongoing costs.

To meet the distinct cooling demands of each laser type, TEYU Chiller Manufacturer provides specialized chiller solutions.

TEYU CWFL series industrial chillers are engineered for fiber lasers, offering dual-circuit refrigeration to support 1kW–240kW laser equipment for cutting, welding, and engraving.

TEYU CW series industrial chillers are tailored for CO₂ lasers, delivering cooling capacities from 600W to 42kW and precision temperature control (±0.3°C, ±0.5°C, or ±1°C). They're suitable for 80W–600W glass CO₂ laser tubes and 30W–1000W RF CO₂ lasers.

Whether you're running a high-power fiber laser or a precision CO₂ laser setup, TEYU Chiller Manufacturer offers reliable, efficient, and application-matched cooling solutions to keep your operations running smoothly.

Spring and Summer Maintenance Guide for TEYU Water Chillers

As temperatures rise and spring transitions into summer, industrial environments become more challenging for cooling systems. At TEYU S&A, we recommend targeted seasonal maintenance to ensure your 

 

1. Maintain Adequate Clearance for Efficient Heat Dissipation

Proper clearance around the chiller is critical to maintaining effective airflow and preventing heat buildup. The requirements vary based on the industrial chiller’s power:

❆ Low-power chiller models: Ensure at least 1.5 meters of clearance above the top air outlet and 1 meter around the side air inlets.

❆ High-power chiller models: Provide at least 3.5 meters of clearance above and 1 meter at the sides to prevent hot air recirculation and performance degradation.

Always install the unit on a level surface with no obstruction to airflow. Avoid tight corners or confined spaces that restrict ventilation.

2. Avoid Installing in Harsh Environments

Avoid Chillers should be kept away from areas with the following risks:

❆ Corrosive or flammable gases

❆ Heavy dust, oil mist, or conductive particles

❆ High humidity or extreme temperatures

❆ Strong magnetic fields

❆ Direct exposure to sunlight

These factors may severely affect performance or shorten the equipment's lifespan. Choose a stable environment that meets the chiller's ambient temperature and humidity requirements.

3. Smart Placement: What to Do & What to Avoid

❆ Do place the chiller:

     On flat, stable ground

     In well-ventilated areas with sufficient space around all sides

❆ Don't:

     Suspend the chiller without support

     Place it near heat-generating equipment

     Install in unventilated attics, narrow rooms, or under direct sunlight

Proper positioning reduces thermal load, enhances cooling performance, and supports long-term reliability.

3. Keep Air Filters & Condensers Clean

Spring often brings increased airborne particles such as dust and plant fibers. These can accumulate on filters and condenser fins, obstructing airflow and reducing cooling efficiency.

Clean Daily in Dusty Conditions: We recommend daily cleaning of the air filter and condenser during dusty seasons.

⚠ Use Caution: When cleaning with an air gun, keep the nozzle about 15 cm from the fins and blow perpendicularly to avoid damage.

Routine cleaning helps prevent over-temperature alarms and unplanned downtime, ensuring stable cooling throughout the season.

Why Spring & Summer Maintenance Matters

A well-maintained TEYU water chiller not only ensures consistent cooling but also helps prevent unnecessary wear and energy loss. With smart placement, dust control, and environmental awareness, your equipment stays in optimal condition, supporting continuous productivity and extending service life.

 

Spring & Summer Reminder:

During spring and summer maintenance, prioritize tasks such as ensuring adequate ventilation, regularly cleaning air filters and condenser fins, monitoring ambient temperature, and checking water quality. These proactive steps help maintain stable chiller performance under warmer conditions.

How to Prevent Heat-Induced Deformation in Laser Machining

Laser processing of highly reflective materials—such as copper, gold, and aluminum—presents unique challenges due to their high thermal conductivity. Heat is quickly dispersed throughout the material, enlarging the heat-affected zone (HAZ), altering mechanical properties, and often resulting in edge burrs and thermal deformation. These issues can compromise precision and overall product quality. However, several strategies can effectively mitigate these thermal challenges.

1. Optimize Laser Parameters

Adopting short-pulse lasers, such as picosecond or femtosecond lasers, can significantly reduce thermal impact. These ultra-short pulses act like precision scalpels, delivering energy in concentrated bursts that limit heat diffusion. However, determining the ideal combination of laser power and scanning speed requires thorough experimentation. Excessive power or slow scanning may still cause heat accumulation. Careful calibration of parameters ensures better control over the process, reducing unwanted thermal effects.

2. Apply Supporting Techniques

Local Cooling: Using industrial laser chillers for localized cooling can rapidly dissipate surface heat and limit heat spread. Alternatively, air cooling offers a gentler and contamination-free solution, especially for delicate materials.

Sealed Chamber Processing: Conducting high-precision laser machining in vacuum or inert gas environments within a sealed chamber reduces thermal conduction and prevents oxidation, further stabilizing the process.

Pre-Cooling Treatment: Lowering the material's initial temperature before processing helps absorb some of the heat input without exceeding thermal deformation thresholds. This technique minimizes heat diffusion and improves machining accuracy.

By combining laser parameter optimization with advanced cooling and processing strategies, manufacturers can effectively reduce thermal deformation in highly reflective materials. These measures not only enhance laser processing quality but also extend equipment longevity and improve production reliability.

Does Your Press Brake Need an Industrial Chiller?

Hydraulic press brakes generate substantial heat during operation, mainly from the hydraulic system. While many machines include built-in air-cooled radiators, these are not always sufficient under demanding conditions. In high-intensity or high-temperature environments, an 

When Does a Press Brake Need a Chiller?

High-Intensity, Continuous Operation: Long hours of processing thick or high-strength materials like stainless steel can cause excessive heat buildup.

High Ambient Temperatures: Poorly ventilated workshops or hot summer months can significantly reduce the efficiency of internal air cooling.

Precision and Stability Requirements: Rising oil temperatures reduce viscosity, destabilizing system pressure and increasing internal leakage, directly impacting bending angle and dimensional accuracy. A chiller keeps hydraulic oil at an optimal, stable temperature.

Inadequate Built-in Cooling: If the oil temperature regularly exceeds 55°C or even 60°C, or if precision and pressure fluctuations occur after long operation, an external chiller is likely necessary.

Why an Industrial Chiller Adds Value

Consistent Oil Temperature: Maintains bending accuracy and repeatability across production runs.

Enhanced Equipment Reliability: Prevents overheating-related failures, such as damaged hydraulic components, degraded seals, and oil oxidation, minimizing downtime.

Extended Equipment Lifespan: Protects the hydraulic system's core components from thermal stress and wear.

Higher Productivity: Enables stable, full-load operation over extended periods without compromising performance.

While small, intermittently used press brakes may function well with internal cooling, mid-to-large hydraulic press brakes used in continuous, high-load applications or high-temperature settings will benefit greatly from an industrial chiller. It's not just a helpful add-on—it's a smart investment in performance, longevity, and production efficiency. Always monitor your machine's oil temperature and operational behavior to make an informed decision.

How to Keep Your Water Chiller Cool and Steady Through the Summer?

When summer hits, even water chillers start to "fear the heat"! Inadequate heat dissipation, unstable voltage, frequent high-temperature alarms... Are these hot-weather headaches troubling you? Don't worry—TEYU S&A engineers offer some practical cooling tips to help your 

1. Optimize the Operating Environment for Chillers

* Place It Properly—Create a "Comfort Zone" for Your Chiller

To ensure effective heat dissipation, the chiller should be positioned with enough space around it:

For low-power chiller models: Allow ≥1.5m of clearance above the top air outlet, and maintain ≥1m distance from side air inlets to any obstacles. This ensures smooth airflow circulation.

For high-power chiller models: Increase the top clearance to ≥3.5m while keeping side air inlets ≥1m away to prevent hot air recirculation and efficiency loss.

* Keep Voltage Stable – Prevent Unexpected Shutdowns

Install a voltage stabilizer or use a power source with voltage stabilization, which helps avoid the abnormal chiller operation caused by unstable voltage during summer peak hours. It is recommended that the electric power of the voltage stabilizer be at least 1.5 times greater than that of the chiller.

* Control Ambient Temperature – Boost Cooling Performance

If the operating ambient temperature of the chiller exceeds 40°C, it may trigger a high-temperature alarm and cause the chiller to shut down. To avoid this, keep the ambient temperature between 20°C and 30°C, which is the optimal range.

If the workshop temperature is high and affects the equipment's normal use, consider physical cooling methods such as using water-cooled fans or water curtains to lower the temperature.

2. Perform Regular Chiller Maintenance, Keep the System Efficient Over Time

* Regular Dust Removal

Regularly use an air gun to clean the dust and impurities from the dust filter and condenser surface of the chiller. Accumulated dust can impair heat dissipation, potentially triggering high-temperature alarms. (The higher the chiller power, the more frequently dusting is required.)

Note: When using an air gun, maintain a safe distance of about 10cm from the condenser fins and blow vertically toward the condenser.

* Cooling Water Replacement

Replace the cooling water regularly, ideally every quarter, with distilled or purified water. Also, clean the water tank and pipes to prevent deterioration of water quality, which can affect cooling efficiency and equipment lifespan.

* Change Filter Elements—Let the Chiller "Breathe" Freely

Filter cartridge and screen are prone to accumulating dirt in chillers, so they require regular cleaning. If they are excessively dirty, replace them promptly to ensure stable water flow in the chiller.
