Product Details

The industrial air-cooled screw chiller has many outstanding features. The unit adopts an efficient screw compressor, which runs smoothly and energy-saving, and can adapt to long-term high-intensity work requirements. The air-cooled design eliminates complex water cooling installation and only requires external power supply and ventilation conditions, which is convenient and fast, greatly reducing the initial infrastructure cost.
It is equipped with a large-area finned condenser with extremely high heat transfer efficiency. The precise temperature control system can control the water temperature within a very small fluctuation range, meeting the strict requirements of industrial production for cooling water temperature stability. The intelligent control system realizes remote monitoring and automated operation, with timely fault warning function to remind maintenance and ensure continuous and efficient production. It is widely used in fields such as chemical, plastic, and food processing.
