HeRL02-RM
Bluefors announces the Cryomech HeRL02-RM – a new helium reliquefier designed specifically for helium recovery from a single nuclear magnetic resonance (NMR) unit. Helium reliquefiers help to conserve the use of valuable helium, safeguarding users against helium supply issues and protecting against helium price fluctuations. The system creates a closed-loop, zero-boil-off system for NMR magnets. Boiled-off helium is passed through a vapor return line to the pulse tube cryocooler-powered reliquefier, which instantly liquefies the boil-off and returns it to the magnet’s helium bath. The new helium reliquefier model utilizes a remote motor to minimize vibrations that might otherwise interfere with sensitive NMR spectroscopy. The HeRL02-RM has been field tested on multiple units of varying magnet strength with no effect on the results. The Cryomech HeRL02-RM can be easily installed through an existing fill port, and operates reliably and safely 24 hours a day, seven days a week. For facilities with greater helium boil off, Bluefors continues to offer full scale helium recovery solutions.
