The Hanzhong water-cooled chiller adopts an efficient and reliable Hanzhong screw compressor (optional from well-known brands such as Germany's Bizer or Italy's Lefcon) as the core component, which has the characteristics of smooth operation, low vibration, low noise, energy saving and high efficiency, and easy maintenance. The unit can provide cold water at room temperature ranging from 5 ℃ to 25 ℃, or customize special working conditions according to demand (such as ethylene glycol solution at 0 ℃ to -4 ℃ or large temperature difference cold water), widely used in industries such as central air conditioning, steel, chemical, food, and medicine. It is equipped with an intelligent PLC control system that supports remote monitoring, automatic energy regulation (multi-stage capacity control), and multiple safety protection functions (such as high and low voltage protection, antifreeze protection, etc.) to ensure stable operation of the unit. Some models can also use environmentally friendly refrigerants or heat recovery designs to meet diverse industrial needs.
