Heat accumulation in industrial manufacturing not only impairs product quality but also severely constrains production efficiency. As the core equipment for removing thermal loads, refrigeration chillers precisely absorb heat from process circulating water using the principle of phase-change heat absorption by liquid refrigerants. In large-scale manufacturing bases and centralized cooling systems, large-scale chillers serve as essential infrastructure to ensure the continuous operation of entire production lines, with screw chillers commonly powering their core. The unique twin-rotor stepless regulation structure of screw compressors grants these units exceptional part-load efficiency and extremely low failure rates, making them the preferred solution for high-capacity, continuous cooling.

Installation conditions and safety standards for chillers differ significantly across industries. In environments characterized by poor water quality, water scarcity, or limited physical space, air-cooled chillers eliminate the need for cooling towers and cooling water pumps by discharging heat directly into the atmosphere via axial fans, significantly simplifying on-site piping layouts. In contrast, the severe heat release of reactors and corrosive media in the chemical industry impose stringent demands on equipment. Specialized chemical chillers utilize explosion-proof engineering, corrosion-resistant heat exchanger materials, and multiple safety interlock designs to effectively prevent media leakage and safety hazards, safeguarding chemical production.

Upgrades in industrial manufacturing technologies are driving refrigeration equipment to evolve deeper along two dimensions: "lower temperatures" and "more precise control." Under extreme working conditions such as pharmaceutical purification and gas-liquid separation, ultra-low temperature chillers rely on dedicated cascade refrigeration technology to operate stably in extreme temperature ranges from −40°C to −100°C, meeting the requirements of cryogenic processes. Simultaneously, during the coating process in semiconductor and precision optics fields, specialized coating chillers focus on micro-level temperature control of targets and vacuum chambers. This effectively prevents film cracking and uneven thickness caused by thermal expansion, demonstrating the indispensable value of specialized refrigeration equipment in high-end manufacturing.
