4KGM Freezer Machine [Manufactured by Sumitomo Heavy Industries] [Authorized Dealer]
The 4K-GM ultra-low temperature refrigeration system at Sumitomo Heavy Industries is highly reliable and orientation-free, making it suitable for a wide range of applications.
It is used for reducing helium evaporation (such as in MRI), cooling superconducting magnets, and cooling sensors. With the price of liquid helium skyrocketing and its availability becoming extremely difficult, it is recommended as an alternative to liquid helium. ● You can download the "comprehensive catalog" that includes this product.
