Introduction to ASU
Air Separation Unit (ASU) is a crucial industrial equipment that separates atmospheric air into its primary components, such as nitrogen, oxygen, and argon, through various processes like cryogenic distillation. These separated gases have a wide range of applications in multiple industries. Oxygen is widely used in steelmaking, chemical production, and medical treatment. Nitrogen is utilized for inerting, food preservation, and electronics manufacturing. Argon is essential in the welding and metalworking industries. In China, with the rapid development of industries such as steel, chemical, and electronics, the demand for ASU has been increasing steadily, leading to the emergence of many excellent ASU suppliers.
