Note: The maximum filling capacity is calculated based on the boiling point of the liquid under normal atmospheric pressure. The actual filling capacity is affected by the liquid temperature and pressure inside the container, which is about 95% of the maximum theoretical filling capacity, and about 90% for natural gas.

Main Applications

1.to fill liquid oxygen for medical use, as an equipment for providing LO2;
2.to fill oxygen for the cutting, welding, and heating of metal in industry;
3.to fill liquid argon for argon-arc welding and other protection occasion of argon;
4.to fill liquid nitrogen for the protective use by high nitrogen, and the field of food, pharmaceutical, biotech, superconduction etc.
