Gelen, and D. Bolusse In 1980, the firm of Thermodyne began to take up new technologies for making centrifugal compressors that incorpo- rated units that did not require lubrication. Users considered that 70% of the problems arising with centrifugal compressors are related to the oil systems used to lubricate the bearings and seals at the ends of the shafts. Also, the size and mass of these oil systems as made in accordance with API 614 standards were comparable with the parameters of the machines themselves. Research was done on two technologies that allow one to avoid using oil in centrifugal compressors: dry gas seals and magnetic bearings, and from these the firm of Thermodyne devised machines that combine these technologies. When such machines were operated in various branches of industry, good results were obtained and valuable experience was accumulated. During the design and manufacture of centrifugal compressors based on oil-free technology, the main developments occurred in machines equipped with dry gas seals. Four compressors of that type were equipped with active magnetic bearings AMB, and
