Laser chillers are currently widely used in the laser production and processing industry, such as various types of lasers and laser equipment with various powers. They are powerful assistants for lasers and laser equipment.

Many friends in the laser industry may have a headache selecting the water chiller used in the laser industry, after all, choosing a water chiller that matches the laser cutting machine you use can greatly improve the service life and processing accuracy of the laser water chiller, and maximize the performance of the laser equipment. This is also what we often refer to as a laser chiller. So, what are the considerations when choosing a laser chiller?


1、 The cooling capacity of the chiller should be considered: as the name suggests, it refers to the actual cooling capacity of the chiller. The heat absorbed by the chiller from the equipment that needs to be cooled per unit time during operation is an indicator that measures the cooling capacity of the chiller. It is also an indicator for the selection of laser chillers.


2、 We need to determine the cooling water volume of the chiller based on the usage of the laser cutting machine: many customers generally pay attention to the cooling capacity and often overlook the indicator of cooling water volume. The refrigeration capacity represents the cooling capacity provided by the compressor, while the chilled water volume represents the ability of the chiller to carry away heat.


3、 Understanding thermal efficiency and water tank capacity: The above two concepts lead to the concepts of chiller thermal efficiency and water tank capacity, which are the two indicators of the compressor's working throttling control method and water tank size. Generally, the larger the water tank, the better, but different compressor control methods (capillary or thermal expansion valve) may vary greatly in design. This is the same compression mechanism cooling capacity and water tank capacity, and the operation control method with PID feedback function will greatly improve the overall cooling capacity of the system.

4、 Temperature control accuracy: This indicator comes from the requirements of the laser. For semiconductor lasers, the temperature control accuracy should be ± 0.1 ℃, which requires the compressor to predict temperature changes and adapt to load changes. Generally, a chiller with an integrated temperature control module cannot achieve this. Of course, for CO2 lasers, the temperature requirement is between ± 2 ℃ and ± 5 ℃, which can be achieved by most specialized chillers on the market.


5、 The comprehensive indicators of water quality requirements, water filtration, and water circulation system materials are often overlooked, but they are very important and directly affect the lifespan of laser chillers. Therefore, during the installation of the laser chiller, water treatment operations can be carried out on the water quality or filters can be installed to prevent various impurities from entering the pipeline and affecting the operation of the chiller.
