Product Details

    CANGAS® on-site oxygen generator/plant, continuously generate high quality oxygen gas meeting requirements of medical respiratory oxygen.

    It ends days when medical institutions rely on traditional costly liquid oxygen and cylinder oxygen. They have passed People’s Republic Of China Registration Certification.

    It wins good reputation from clients from China Mainland, Kazakhstan, Cyprus, Indonesia, Bangladesh, Thailand, Nepal, Angola, etc out of its reliability, economy, convenience, and proven applications in medical industry.

Contrast of three medical oxygen generation methods

   PSA oxygen generation technology is popular globally, which has partly substituted oxygen cylinder method and cryogenic method, and become an important part of modernized hospitals.

   Calculated as cylinder oxygen consumption of 1500 cylinders, it will save USD81,415 than liquid oxygen in three years, and save USD206,030 than cylinder oxygen(as liquid oxygen USD230.8/Ton, cylinder oxygen USD4.6/cylinder)

CAPO Series & CFS Series&&CAPO-HP Series

    CANGAS CAPO series oxygen machines generate 93±3% purity oxygen. This purity is the most applicable in lots of industries, with its unique advantage of cost. Generally 1~1.5kw per cubic meter oxygen. Much more economical than buying liquid oxygen in cylinders.

    CANGAS CFS Series (Oxygen cylinder Filling System), an self-serviced oxygen generation and cylinder filling system. With oxygen generation system it fills generated oxygen into cylinders. The system is an ideal choice if the end users for oxygen are in mountains or mines/oilfield. Hospitals require it for standby of oxygen once breakdown or blackout.

    CANGAS CAPO-HP Series high purity oxygen machine generates high purity oxygen at 98±1%. It is an unique technology developed by CANGAS. This purity is specially used for steel cutting, medical and other high fields requiring high purity oxygen.

PSA Oxygen Principles

  The principles of Pressure Swing Adsorption (PSA) oxygen generator are adsorption and desorption.

  Each gas has a characteristic adsorption rate that when adsorbed by Zeolite Molecular Sieve (ZMS).

 ZMS has large surface area containing a mass volume of micro pores and passageways. Nitrogen has a higher adsorption rate than oxygen when delivered to the ZMS bed after pressurized. When compressed air enters ZMS, oxygen molecules are able to pass through this large surface, and nitrogen molecules are adsorbed to the surface area.

  Adsorption and desorption/diffusion are the general principles of the PSA system since each gas has a characteristic adsorption rate that is a function of its ability to be adsorbed by a molecular sieve. The adsorption process can produce a range of gas with purities more than 90% oxygen.

 The different capacities that ZMS adsorbing O2 molecule and N2 molecule can be shown by the adsorption balance curve below.

As the ZMS is saturated with nitrogen, it should be depressurized to regenerate for next cycle. We use two adsorption vessels filled with ZMS to produce a continuous stream of oxygen.

 During depressurization, the oxygen of lower purity than required is transferred to another vessel first, which is called pressure equalization. Pressure equalization donates to higher efficiency and less energy consumption. Then the adsorption and desorption/regeneration processes switch in the two adsorption towers.
