Evaperative screw chiller is an integrated refrigeration system designed to achieve directional heat transfer through mechanical cycling. Its core function is to efficiently transfer heat from low-temperature environments to high-temperature environments. The equipment comprises a closed-loop system integrating key components such as compressors, condensers, expansion valves, and evaporators, which utilize the phase-change cycle of refrigerants. The system is widely applied across industries, including: New Energy, Industrial Manufacturing, Aerospace Testing, Pharmaceuticals, Automotive & Die-Casting.
Aligned with carbon neutrality objectives, refrigeration units leverage continuous technological innovation to ensure reliable civil cold chain operations and industrial production support. They are emerging as pivotal infrastructure for advancing green low-carbon development.
