Dewar Fill / Switchers

CryoWorks supplies Manual or Automatic Dewar Fill Stations. These stations fill portable liquid nitrogen cylinders with low-pressure liquid from either a piping system or bulk tank. With our automatic option, you can avoid overfills, a risk to your employees, and the wasted time that is otherwise used to fill your nitrogen cylinder. This automated system uses a cryogenic sensor and control valve to stop filling when the container is full.
