1. Electronic control system: including PLC, circuit system, external type, valve, etc.

2. Air tank buffer device: it is composed of air tank and air valve, which is mainly used to ensure the smooth use of air tank.

3. Nitrogen buffer tank: including nitrogen buffer tank, valve, used for nitrogen storage, first to ensure the stability of gas.

4. Nitrogen generator: it includes two adsorption towers filled with carbon molecular sieve, and automatic control valve which can be said to be the core of nitrogen making machine.

5. Air filter system: mainly composed of the air cooler, filter, oil remover, etc., mainly used to clean air and dust and remove oil.

Nitrogen is an indispensable gas in our laboratory and industrial production. It has many uses and a large amount of consumption. At present, there are many air separation equipment manufacturers in the market, and there are many ways of nitrogen supply. Traditional liquid nitrogen tank and nitrogen supply of liquid nitrogen tower are classic, but they are in danger of death.
