The Sumitomo F50 is a mid-sized, water-cooled, three-phase compressor from SHI’s Freedom® series, widely used in critical applications such as Magnetic Resonance Imaging (MRI) systems. It operates on the Gifford-McMahon cycle, using helium gas to provide cooling capacity. The compressor works with a cold head—the unit that provides the actual refrigeration—by supplying it with high-pressure helium gas. Key physical and operational parameters of the F50 are:
