Air Cooled Screw Low Temperature Chiller
The air cooled screw low temperature chiller is designed for large-scale industrial applications
requiring stable and continuous cooling under sub-zero conditions. With a wide cooling capacity
range and high system reliability, it is especially suitable for long-term operation in demanding
industrial environments.
This series adopts semi-hermetic screw compressors with multi-stage capacity control, combined
with high efficiency air cooled condensers and shell and tube or stainless steel plate evaporators.
The system ensures excellent performance, precise temperature control and high energy efficiency
under low temperature working conditions.
Equipped with comprehensive safety protections and intelligent control, the air cooled screw
low temperature chiller is an ideal solution for industrial glycol cooling systems and
low temperature process cooling.
Applications
- Chemical and petrochemical low temperature processes
- Pharmaceutical production and low temperature reactions
- Battery manufacturing, testing and formation cooling
- Food processing, freezing and cold storage systems
- Material testing, environmental simulation chambers
- Large-scale industrial glycol water cooling systems
