As an excellent inert gas, nitrogen is used more and more widely in many fields. At present, there are many nitrogen making technologies adopted in the world. This is a compressed air purification treatment, using nitrogen and oxygen molecules are not the same in the state of motion of polymer hollow fiber tube they separated device to make the nitrogen concentration to use certain requirements for storage or for direct use. Nitrogen purity not less than 97%.
Nitrogen making machine is mainly used for large ships, oil tankers, liquefied gas vessels, chemical tankers, refrigerated transport vessels and other types of ships, drilling platform explosion suppression, anti-burning anti corrosion and storage; for oxygen and chemical explosion; smelting, mechanical and electrical for oxygen barrier protection for gas storage and warehouse.
