Oxygen generators belong to a type of air separation equipment (referred to as air separation equipment). According to different classification methods, the types of oxygen generators will also be different.
1. According to product purity
● High-purity oxygen equipment: devices that produce oxygen with a purity of more than 99.2%;
● Low-purity oxygen equipment: devices that produce oxygen purity below 90%;
2. By product type
● Single-height product equipment: only producing high-purity oxygen;
● Full extraction equipment: with a device for extracting rare gases.
3. By product output
● Small equipment: equipment below 800 cubic meters per hour;
● Medium-sized equipment: 1000-6000 cubic meters per hour;
● Large equipment: equipment above 10,000 cubic meters per hour.
4. According to the separation principle
● cryogenic distillation;
● Molecular sieve adsorption method
● Membrane penetration method.
5. According to the working pressure
● High-pressure device: a device with a working pressure of 10.0 to 20.0 MPa;
● Medium pressure device: a device with a working pressure of 1.0 to 5.0 MPa;
● Full low pressure device: a device with a working pressure of 0.5 to 0.6 MPa.
No matter which classification method is used, it represents a certain characteristic of the product, so that people can quickly understand whether the product is suitable for their own needs. The above classifications are some of the more common classifications, and there may be other classification methods, which are not listed here.
