Water Cooled Screw Low Temperature Chiller
The water cooled screw low temperature chiller is specially designed for large-capacity industrial
cooling applications operating under sub-zero temperature conditions. With stable performance,
high efficiency and reliable operation, it is widely used in continuous industrial processes
requiring precise low temperature control.
This series adopts semi-hermetic screw compressors with multi-stage capacity control, combined
with high efficiency shell and tube evaporators and condensers. The optimized refrigeration system
ensures excellent heat exchange performance, reduced energy consumption and long service life.
Designed for glycol water systems, the unit can operate reliably at -10℃, -20℃ and -30℃ chilled
water outlet temperatures, making it an ideal solution for demanding industrial low temperature
applications.
Applications
- Chemical and petrochemical low temperature processes
- Pharmaceutical production and reaction cooling
- Battery manufacturing, testing and formation cooling
- Food processing, freezing and cold storage systems
- Material testing laboratories and environmental chambers
- Large-scale industrial glycol cooling systems
