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.
