Sujing Busch's air-cooled oil-free variable-frequency chiller is a highly efficient and energy-saving refrigeration device. It combines the advantages of an air-cooled system, an oil-free compressor, and variable-frequency technology, offering many benefits that are very popular in industrial and commercial refrigeration applications. Through variable-frequency technology, the chiller can automatically adjust the operating speed of the compressor according to changes in the cooling load, reducing energy consumption and achieving high energy efficiency. The oil-free compressor does not use lubricating oil, reducing the risk of oil pollution and being environmentally friendly. Since no lubricating oil is used in the oil-free compressor, the costs and labor associated with oil maintenance an
