Typical Applications

In plastics processing, water-cooled scroll chillers cool molds during injection molding, extrusion, and blow molding, helping to reduce deformation, improve surface quality, and maintain high production efficiency.
Chemical and pharmaceutical operations use scroll chillers for precise temperature control in reaction vessels, stable cooling during drug synthesis, and steady fermentation tank conditions that keep processes consistent and product quality reliable.
In food production, they handle rapid cooling after sterilization, manage temperatures for dairy pasteurization and beer fermentation, and provide pre-cooling in cold storage environments.
For metalworking and machinery, water-cooled scroll chillers lower the temperature of cutting fluids, welding units, and machine tool hydraulic systems, minimizing thermal distortion and extending tool life.
Electronics and electroplating benefit from consistent cooling for semiconductor manufacturing equipment and plating baths, ensuring stable performance of components and a high-quality finish on coatings.
In hospitals and laboratories, chillers help maintain the temperature under control in operating rooms, medical imaging systems such as MRI scanners are properly cooled, and precision instruments in labs operate under stable conditions.

What type of chiller is most suitable for data centers?

Data centers require cooling equipment that can operate year-round, deliver precise temperature control, and maximize energy efficiency. Variable-frequency centrifugal chillers and magnetic bearing centrifugal chillers are the best options fo data centers, as they can maintain stable room temperatures with a precision of ±0.5 °C while offering superior energy-saving performance.

Which type of chiller is recommended for factories in cold regions?

For facilities located in cold climates that require cooling throughout the year, free cooling screw chillers are a suitable choice. These cooling systems take advantage of natural ambient cold to lower the chilled water temperature, significantly reducing energy consumption.

Which cooling systems are suitable for environments where noise levels must be kept low?

Magnetic bearing centrifugal chillers are often the preferred choice in noise-sensitive environments. Their design eliminates mechanical friction during operation, which significantly reduces noise while ensuring stable and efficient performance.
