A laser chiller is a refrigeration-based cooling unit that produces a cooling effect for laser processing, configured to circulate chilled water around the laser tube and release heat from the system.

Laser chillers are equipped with condensers, evaporators, rotary or piston compressors, heat exchangers, expansion valves, temperature alarms, coolant filters, protection devices, temperature controllers, and power supplies for efficient working.

Laser chillers are known for their many advantages in different fields, as follows; During laser processing, high temperatures are generated, which affects the wavelength of the laser, and thus the optical efficiency. Laser chillers regulate the laser temperature through chilled water circulation and PLC based temperature controllers.

Laser processing is used for metal cutting by generating heat that can damage machine components. Laser chillers prevent heat loss from the coils around the laser machine by heat exchange through the cooling effect. Laser chillers ensure highly reliable performance by installing protection devices that preemptively observe fluctuations in coolant flow, temperature and pressure flow and either adjust at set points or simply stop the unit.

Laser chillers are equipped with air filters to ensure that the compressor works properly and efficiently to achieve stable pressure and to remove dust particles from the coolant and prevent blockage flow in. Instead of installing multiple refrigeration circuits, the laser chiller is equipped with a hot gas bypass valve that allows the refrigeration circuit to be adjusted to handle multiple applications at once. The laser chiller has a compact design and small footprint with fixed casters for easy installation. Laser chillers produce cooling and are used in a large number of laser applications such as:

Drilling, Lithography, Laser Cutting, Fiber Optics, Laser Measurement Systems, Engraving, Laser Bonding, Spectroscopy, Bio-Optics, Laser Printing, Plastic Welding, Inspection and Imaging.
