TEYU CWFL Series Fiber Laser Chillers Ensure Stable Cooling for High Power Laser Systems

As global laser manufacturing continues to advance toward higher power, precision, and intelligence, temperature control stability has become a key factor determining laser equipment performance and lifespan. With over two decades of expertise in industrial laser refrigeration, TEYU has developed the CWFL Series Fiber Laser Chillers, offering a comprehensive cooling solution covering 1000W to 240,000W, ensuring precise temperature management for fiber lasers worldwide.

The CWFL Series is engineered with the core principles of full power coverage, dual temperature control, intelligent operation, and industrial-grade reliability, making it one of the most versatile cooling systems for fiber laser equipment on the market.

1. Full Power Range Support
From 500W to 240,000W, CWFL fiber laser chillers are compatible with major global fiber laser brands. Whether for small-scale micromachining or heavy-duty thick plate cutting, users can find a perfectly matched cooling solution within the CWFL family. A unified design platform ensures consistency in performance, interfaces, and operation across all models.

2. Dual-Temperature, Dual-Control System
Featuring independent dual water circuits, CWFL fiber laser chillers separately cool the laser source and laser head, one high-temperature circuit and one low-temperature circuit.
This innovation meets the distinct thermal demands of different components, ensuring beam stability and minimizing thermal drift caused by temperature fluctuations.

3. Intelligent Temperature Control
Each CWFL unit offers two temperature control modes: intelligent and constant.
In intelligent mode, the chiller automatically adjusts the water temperature based on ambient conditions (typically 2°C below room temperature) to prevent condensation.
In constant mode, users can set a fixed temperature for specific process needs. This flexibility allows the CWFL Series to perform reliably in diverse industrial environments.

4. Industrial Stability and Smart Communication
CWFL fiber laser chillers (above the CWFL-3000 model) support the ModBus-485 communication protocol, enabling real-time data interaction with laser equipment or factory automation systems.
With built-in safety features such as compressor delay protection, overcurrent protection, flow alarms, and high/low temperature warnings, CWFL fiber laser chillers deliver 24/7 reliable performance in demanding applications.

•Low-Power Models (CWFL-1000 to CWFL-2000)
Designed for 500W–2000W fiber lasers, these compact chillers feature ±0.5°C temperature stability, space-saving structures, and dust-resistant designs—ideal for small workshops and precision applications.

•Mid-to-High Power Models (CWFL-3000 to CWFL-12000)
Models such as the CWFL-3000 deliver up to 8500W of cooling capacity and feature dual-loop systems with communication support.
For 8–12kW fiber lasers, the CWFL-8000 and CWFL-12000 models offer enhanced cooling efficiency for continuous industrial production, ensuring stable laser output and minimal temperature deviation.

•High-Power Models (CWFL-20000 to CWFL-120000)
For large-scale laser cutting and welding, TEYU's high-power lineup — including the CWFL-30000 — offers ±1.5°C control precision, a 5°C–35°C temperature range, and eco-friendly refrigerants (R-32/R-410A).
Equipped with large water tanks and powerful pumps, these chillers guarantee stable operation during long, high-load processes.

In July 2025, TEYU launched the CWFL-240000, the world's first 240kW fiber laser chiller, marking a major leap in high-power laser thermal management.

The CWFL-240000 ensures stable cooling even under extreme loads, thanks to optimized heat exchange design and enhanced core components. Its smart adaptive refrigeration system adjusts compressor output based on laser load, achieving efficient, energy-saving performance.

Through ModBus-485 connectivity, users can perform remote monitoring and parameter control to optimize smart production lines.
The CWFL-240000 was honored with the "OFweek 2025 Technology Innovation Award".

The TEYU CWFL Series is trusted across industries such as metal processing, automotive manufacturing, aerospace, shipbuilding, and rail equipment.
Metal cutting – Keeps beam energy stable for smoother, higher-quality edges.
Automotive welding – Maintains consistent weld seams and minimizes thermal distortion.
Heavy industry – Models like CWFL-240000 ensure reliable performance in high-power laser cutting and welding operations.

From kilowatt-level precision machining to 240kW ultra-high-power cutting, the TEYU CWFL Series safeguards every laser beam with accurate temperature control and unmatched reliability.

With a commitment to Integrity, Practicality, and Innovation, TEYU continues to drive the future of laser manufacturing toward higher power, higher precision, and higher efficiency.
