TEYU High Power Fiber Laser Cooling System CWFL-40000 is a high-performance laser chiller specially designed for 40kW high power fiber laser cutting machine, which offers advanced features while also making cooling easier and more efficient. With dual cooling loops, this recirculating water chiller has enough capacity to cool the fiber laser and the optics independently and simultaneously. The refrigerant circuit system adopts solenoid valve bypass technology to avoid the compressor's frequent start/stop to prolong its service life. All of the components are carefully selected to ensure reliable operation. Fiber Laser Chiller CWFL-40000 provides an RS-485 interface for communication with the high power fiber lasers. A smart temperature controller is installed with advanced software to optimize the water chiller's performance. A variety of built-in alarm devices to further protect the chiller and laser equipment. In compliance with CE, RoHS and REACH approval. Customization is available.
