Nitrogen, as a convenient and inexpensive inert gas, is colorless and odorless; in the pharmaceutical industry, it has extensive application value.

Industrial oxygen is a gas used in industrial production and product processing. The quality of the gas is lower than that of medical oxygen, and it may contain impurities harmful to the human body such as carbon monoxide, carbon dioxide, and acetylene.

The pipeline of the medical center oxygen supply system is a part of the gas transmission between the hospital oxygen source and the hospital ward. In terms of design and installation, it should be safe, leak-free, durable, and free of secondary pollution during the transmission process. In general, a set of qualified oxygen supply pipelines can support a powerful oxygen supply and utilization system to ensure the safety and efficiency of medical oxygen use.

As the sustained development of domestic air separation industry, PSA nitrogen generation system or oxygen generation system has also begun to introduce the concept of modularity in the field of design and manufacturing. For nitrogen generation system or oxygen generation system, the use of modularization is of great significance;

​The so-called heat treatment refers to the process of heating and cooling the metal material properly to adjust the metal crystal form. Usually it includes quenching, annealing, tempering, normalization and other treatments. It is a work to change the mechanical properties of metals.

Pressure swing adsorption PSA nitrogen production method and membrane separation nitrogen production method are two normal temperature nitrogen production methods, the difference between the two is:

The central oxygen supply system is an important equipment for medical oxygen supply in hospitals, and is used for patient treatment and diagnosis.

The complete equipment of PSA nitrogen generator is composed of air compressor, compressed air filtration system, PSA nitrogen generator host, automatic control system and air nitrogen buffer tank etc. Among them, the selection of air compressor is very important, it is very important to the performance and stable operation of the whole nitrogen making system.

Nitrogen fresh-keeping is a modified atmosphere fresh-keeping method that prolongs the storage period of products and maintains the original flavor of products. Among them, the nitrogen used can be produced by the PSA nitrogen generator;

​In modern medicine, the quality of the oxygen supply system in the medical center is directly related to the health and even the life of the patient. Therefore, the requirements for the mainstream medical gas supply should be safe, reliable, easy to manage, and low in cost; and the three should be met at the same time.
