Automatic Dewar Filling Station
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.
Eliminate overfilling and loss of LN2.
Create a safer work environment with fill shut off timer, vent safety interlock, and emergency stop.
Eliminate wasted labor and downtime.
Save money by eliminating the need for dewar deliveries.
