Flooded Screw Water Chiller
The flooded screw water chiller is a high-efficiency industrial cooling system designed for
medium and large cooling capacity applications. It adopts a semi-hermetic twin-screw compressor
combined with a high-efficiency shell-and-tube flooded evaporator, delivering superior heat
transfer performance, stable operation and excellent energy efficiency.
In a flooded evaporator design, the heat exchange tubes are fully immersed in liquid refrigerant,
maximizing the effective heat transfer area and significantly improving system COP. This design
is especially suitable for long-term continuous operation with high load stability requirements.
With multi-step or stepless capacity control, industrial-grade electrical components and a full
range of safety protections, the flooded screw chiller is widely used in industrial process
cooling, central cooling plants and large HVAC systems.
Applications
- Plastic injection molding, extrusion and blow molding industries
- Chemical, pharmaceutical and fine chemical process cooling
- Food & beverage processing, fermentation and cold storage systems
- Electronics manufacturing, battery and semiconductor cooling
- Central cooling systems for industrial plants and large commercial buildings
- Energy stations, district cooling and centralized HVAC systems
