Oxygen generator/oxygen plant for room and clinic

The principles of pressure swing adsorption (PSA) Oxygen generator are adsorption and diffusion. Each gas has a characteristic adsorption rate that when adsorbed by Zeolite Molecular Sieve (ZMS). ZMS has large surface area containing volume of micro pores and passageways. Nitrogen has a higher adsorption rate than oxygen. When compressed air enters ZMS, oxygen molecules are able to pass through this large surface. And nitrogen molecules are adsorbed to the surface area. As the ZMS is saturated with nitrogen, it should be depressurized to regenerate for next cycle. We use two towers filled with ZMS to produce a continuous stream of nitrogen. During depressurization, the oxygen of lower purity than required is transferred to another tower, which is called pressure equalization. Pressure equalization donates to higher efficiency and less energy consumption.

Air compressor

Its function is to compress ambient air to a certain pressure for subsequent steps use.

To guarantee its quality of air source, we bought the air compressor from world well-known companies, for example, Atlas.

Filters

Filter will remove the oil, dust and some water in the compressor to ensure the performance of the molecular sieve in the oxygen generator.

Dryer 

The most moisture in the compressed air will be removed by the dryer.

The compressed air is very hot before going into the dryer, and will be cooled down after going into the dryer, meanwhile water will become liquid and then drain to outside.

Oxygen generator

The oxygen generator has two adsorption tanks, one conduct adsorption, at the same time the other one conduct regeneration, this will ensure continuous oxygen supply.
