1. Laser technology

In laser systems, the laser source, beam controller, and electrical control cabinet may all require additional cooling. The chilled water temperature is typically maintained between 15 and 22°C, with temperature accuracy usually specified as ±1 K or ±2 K. Some equipment may demand even tighter tolerances of ±0.5 K, while others impose specific requirements regarding chilled water conductivity and corrosion resistance. During startup, laser systems often have precise water‑temperature specifications, necessitating electric heating in the water circuit. In certain configurations, the beam controller may require a dedicated cooling loop. For specialized applications within laser systems, industrial chillers can be custom‑designed to meet diverse performance criteria.

 

2. Welding

Electrodes, welding furnaces, and cutting tools all require cooling. For example, the electrodes and nozzles of large and medium‑sized welders, as well as the electric furnaces used in the processing of gold and silver jewelry, typically rely on small to medium‑sized chillers. These systems necessitate either an internal–external circulating water pump system or a closed‑tank system.

 

3. Machining

In many machining centers—such as machining centers, lathes, milling machines, and drilling machines—tools or spindles rotate at high speeds, generating heat, while the cutting process itself also produces substantial amounts of thermal energy. In these machine tools, cooling is typically required for components such as the spindle, cutting fluid, lubricating oil, hydraulic oil, and electrical control cabinets.

 

4. Non-cutting processes

Such as EDM machines, polishing machines, and grinding machines. When using a chiller, the water system is prone to clogging by metal chips; therefore, a filter must be installed. An internal–external circulation pump system or a closed‑tank system is required.
