Water Cooled screw chiller
The water cooled screw chiller is a high-capacity industrial cooling system designed for
continuous operation and precise temperature control. It adopts a semi-hermetic screw compressor
combined with high-efficiency shell and tube heat exchangers, delivering stable performance,
excellent energy efficiency and long service life.
By using cooling water as the heat dissipation medium, the unit achieves higher heat exchange
efficiency compared to air-cooled systems, making it especially suitable for large industrial
applications with high cooling demand. Multi-step capacity control and intelligent control logic
ensure accurate temperature regulation under varying load conditions.
With a complete set of safety protections and industrial-grade components, the water cooled screw
chiller is ideal for factories and process systems that require long-term, reliable and energy-
efficient cooling Solutions.
Applications
- Plastic injection molding, extrusion and blow molding production lines
- Chemical, pharmaceutical and petrochemical process cooling
- Food & beverage processing, fermentation and cold storage systems
- Electronics manufacturing, semiconductor and precision equipment cooling
- Data centers, laboratories and centralized industrial cooling plants
- HVAC central cooling systems for factories and large commercial buildings
