A reliable chiller is essential for maintaining the performance, cutting quality, and service life of a CO2 laser tube. Whether you're running a small engraving machine or a high-power laser cutter, selecting the right cooling solution helps prevent overheating and ensures stable operation.
For CO2 laser engraving and cutting applications, the TEYU CW-3000, CW-5000, CW-5200, CW-6000, and CW-6200 are among the most widely used cooling solutions. Here's a quick guide to help you choose the right model for your laser tube power.
Selection Guide
Actual cooling requirements may vary depending on ambient temperature, operating hours, and machine configuration.
1. CW-3000 for CO2 Lasers up to 80W
The CW-3000 is a compact water cooling solution widely used with 40W, 60W, and other low-power CO2 laser engraving machines.
Its compact design, easy installation, and cost-effective operation make it a popular choice for hobbyists, educational users, and small workshops. It is commonly used for engraving wood, acrylic, leather, and other non-metal materials.
2. CW-5000 for 80W–120W CO2 Laser Tubes
For higher-power engraving and cutting applications, the CW-5000 provides active refrigeration and stable temperature control.
It is frequently paired with 80W to 120W CO2 laser tubes used in sign making, advertising production, and light industrial processing. Compared with basic cooling solutions, it offers improved temperature stability for longer operating cycles.
3. CW-5200 for 100W–130W CO2 Laser Systems
The CW-5200 is one of the most popular industrial chillers for CO2 laser applications worldwide.
Designed for 100W to 130W laser tubes, it is also used by some customers for 150W applications under suitable operating conditions. Its balanced cooling performance, compact footprint, and reliable operation have made it a long-time favorite in the laser industry.
4. CW-6000 for CO2 Lasers up to 300W
As laser power increases, cooling demand rises significantly. The CW-6000 is designed for higher-power CO2 laser cutting and engraving systems requiring greater cooling capacity.
It is commonly used in industrial production environments where machines operate for extended periods and stable temperature control is critical to maintaining cutting quality and productivity.
5. CW-6200 for CO2 Lasers up to 600W
The CW-6200 provides even greater cooling capacity for high-power CO2 laser applications.
Suitable for laser tubes up to 600W, it is often selected for demanding industrial processing tasks and continuous production operations. Its powerful refrigeration system helps maintain stable performance even under heavier thermal loads.
What Temperature Is Recommended for a CO2 Laser Tube?
For most CO2 laser applications, cooling water temperatures between 18°C and 22°C are generally recommended.
Excessive temperatures may affect laser output stability and accelerate tube aging, while temperatures that are too low can increase condensation risks. Many users choose to set their chiller around 20°C for daily operation.
Final Thoughts
Choosing the right CO2 laser chiller starts with matching the cooling capacity to your laser tube power.
From the compact CW-3000 for small engraving machines to the high-capacity CW-6200 for industrial CO2 laser systems, TEYU offers cooling solutions for a wide range of engraving and cutting applications. Proper cooling helps improve processing consistency, reduce downtime, and extend the service life of your CO2 laser tube.
