High-Efficiency Air Cooled and Water Cooled Screw Chillers for Industrial Process Cooling Applications.
A screw chiller is a high-capacity industrial cooling system that uses a screw compressor to provide stable and energy-efficient temperature control. Compared with scroll chillers, screw chillers offer higher cooling capacities and are widely used in plastic processing, laser systems, chemical plants, pharmaceutical manufacturing, food processing, and large-scale industrial cooling projects.

A screw chiller is a very effective refrigeration system that produces chilled water for big commercial HVAC systems or industrial applications. It uses a specialized rotary screw compressor to pressurize the refrigerant and power the continuous heat-exchange operation in a continuous vapor compression cycle.
Industrial screw chillers are widely used because of their superior cooling performance and operational reliability.
Screw chillers are suitable for medium to large industrial cooling applications, offering cooling capacities from 100KW to over 3000KW.
Advanced screw compressor technology helps reduce energy consumption and operating costs, especially during long-term continuous operation.
Maintain precise process temperatures to improve product quality and production efficiency.
Designed for continuous industrial production environments with minimal downtime.
Available in air cooled and water cooled configurations to meet different installation requirements.
Industrial-grade components ensure durability and low maintenance costs.
| Feature | Screw Chiller | Scroll Chiller |
| Cooling Capacity | Large | Small to Medium |
| Energy Efficiency | Higher at large loads | Suitable for smaller systems |
| Maintenance | Easier for large systems | Simple structure |
| Service Life | Longer | Moderate |
| Industrial Applications | Heavy-duty industrial cooling | Commercial & light industrial |
Scroll chillers are often suitable for small commercial or light industrial applications. However, for large-scale industrial cooling projects such as plastic injection molding, pharmaceutical manufacturing, chemical processing, and laser cooling systems, screw chillers offer better efficiency, higher cooling capacities, and more reliable long-term operation.
| Feature | Screw | Centrifugal |
| Capacity | Medium-Large | Very Large |
| Initial Cost | Lower | Higher |
| Part Load Efficiency | Better | Better at Full Load |
| Maintenance | Easier | More Complex |

What is a screw chiller and how does it work?
A screw cooled chiller is an industrial cooling system that uses a screw compressor to remove heat from water or process fluids. It works through a vapor-compression cycle: the refrigerant is compressed, condensed, expanded, and evaporated to continuously absorb and release heat, achieving stable cooling performance for industrial applications.
What are the advantages of a screw chiller?
Screw cooled chillers offer high efficiency, stable operation, and strong cooling capacity. Compared with other types of chillers, they feature lower vibration, longer service life, and better performance under continuous heavy-load conditions, making them ideal for industrial production environments.
What industries use screw cooled chillers?
Screw chillers are widely used in plastics processing, chemical production, food processing, pharmaceuticals, data centers, and large industrial manufacturing plants. They are suitable for any process requiring precise and continuous temperature control.
What certifications do your screw cooled chillers have?
Our screw cooled chillers are manufactured under strict quality standards and comply with CE certification and ISO 9001 quality management system, ensuring reliable performance, safety, and international compliance.
Can screw cooled chillers be customized?
Yes, screw chilled systems can be customized based on cooling capacity, temperature requirements, application industry, and installation environment to meet specific project needs.
