The AFS-01 is an automatic shut off liquid nitrogen dewar filling station for standard liquid cylinders.
The AFS-01 is designed to fill portable low pressure liquid nitrogen dewars from a pipe system or bulk tank. The AFS-01 uses a cryogenic sensor to detect a “full” condition. Once full, cryogenic valves shut off the fill cycle maintaining the fill pressure of the liquid cylinder. The liquid cylinder is ready for immediate use.
