Get Instant QuoteProduct Details



Industrial cooling system CWFL-20000 is designed to offer advanced features while also making 20KW fiber laser cooling easier and more efficient. With dual refrigeration circuit, this recirculating water chiller system has enough capacity to cool the fiber laser and the optics independently and simultaneously. All of the components are carefully selected to ensure reliable operation. A smart temperature controller is installed with advanced software to optimize the chiller’s performance. The refrigerant circuit system adopts solenoid valve bypass technology to avoid frequent start and stop of the compressor to prolong its service life. RS-485 interface is provided for communication with the fiber laser system.

Product Details
Dual temperature control

The intelligent control panel offers two independent temperature control systems. One is for controlling the temperature of the fiber laser and the other is for controlling the temperature of the optics.
Dual water inlet and water outlet

Water inlets and water outlets are made from stainless steel to prevent potential corrosion or water leakage.
Easy drain port with valve

Draining process can be controlled very easily.

FAQ
What is the recommended water used in the industrial water chiller?
The ideal water should be deionised water, distilled water or purified water.
How often should I change out the water?
Generally speaking, the water changing frequency is 3 months. It can also depend on the actual working environment of the recirculating water chillers. For example, if the working environment is too inferior, the changing frequency is suggested to be 1 month or shorter.
What is the ideal room temperature for the chiller?
The working environment of the industrial water chiller should be well ventilated and the room temperature should not be higher than 45degree C.
How to prevent my chiller from freezing?
For users living in high latitude areas especially in winter, they often face the frozen water problem. To prevent the chiller from freezing, they can add an optional heater or add anti-freezer in the chiller. For detailed use of the anti-freezer, it is suggested to contact our customer support team (info@whcstek.top) first.
