If you are using bottled nitrogen, you can calculate the amount of nitrogen used per hour based on the amount of bottled nitrogen used. When purchasing a nitrogen generator, you can increase the flow rate appropriately to ensure that there is a margin. If you don’t use bottled nitrogen, you can also purchase it first and make an experimental calculation.

If you are using liquid nitrogen, you can also calculate the amount of nitrogen required per hour based on the amount of liquid nitrogen used, and on this basis, you can select the model of the nitrogen generator by adding some margin. If the box is filled with nitrogen or has space, the approximate amount of nitrogen used can also be calculated based on the volume of the box, the space of the article and other factors.
