GE MRI CSA-71A Shieldcooler Compressor–by Sumitomo: CSA-71A Unit (200VAC Type) P/N – 2166592

This is a high-performance, air-cooled helium compressor unit manufactured by Sumitomo and used in GE MRI systems. It functions by supplying high-pressure helium gas to the MRI’s cold head and re-compressing the returned low-pressure gas. The unit is designed for indoor use and is a crucial component for maintaining the cryogenic cooling of the magnet. It is compatible with various Sumitomo cold heads, including the RDK-408D2, RDK-415D, and others. The CSA-71A is a direct drop-in replacement for any model Sumitomo cold head.
