Liquid Cylinders

 

GL Series - Gas and Liquid Withdrawal - Medium Pressure XL-45, XL-50, XL-55, XL-65, and XL-70
Liquid or Gaseous Nitrogen, Oxygen, Argon, 

These over-the-road transport cylinders feature automatic pressure-building and economizer circuits.  Low-loss holding capabilities help conserve gas during low demand periods.  These units are considered the workhorses of the industry.
