How It Works?

The adsorbent container filled with zeolite preferably adsorbs Nitrogen and CO2; here oxygen is not adsorbed by the Zeolite due to its larger molecular size and passes through the absorber into the feed containers. 

Based on the prescribed time interval, the online adsorber goes into regeneration mode and the adsorbed gas from the Zeolite is expelled into the atmosphere. 

During this process, the oxygen analyzer monitors the oxygen concentration and allows the oxygen gas to be stored. 

If the oxygen concentration is lower than the preset value, the PLC changes the aeration value and clears the gas until it reaches the required purity level.

Working Technology

All pipes of our oxygen generators are made of selective materials such as oil-free medical device copper tubing to ASTM B819 / BSEN 13348. All components and parts that come into contact with oxygen are highly clean in accordance with NFPA 99 / HTM02-01. 

Oxygen generators should be operated in a completely clean and heated environment. BAROTECH series generators can operate between 5 and 45°C (41 to 113°F) but provide the best performance between 20 and 35°C (68 – 95°F). The installation is very easy for the user according to the “Plug and Play” principle. 

The most important factor affecting the performance of O2 generators is clean and dry air.



O2XYRATOR branded oxygen generators are prepared with the experience of BAROTECH engineers. 

The system works on the principle of Pressure Swing Adsorption, commonly called PSA. This conventional gas separation technology is used to separate oxygen from compressed air. 

Main components include:

  • Adsorbent containers, 
  • Balancing tank, 
  • Switching valves, 
  • PLC, 
  • Oxygen analyzer

The main components of the Cryogenic Oxygen Stations are liquid oxygen (LOX) storage tanks and evaporation systems.


BAROTECH LOX tanks are specially designed and manufactured according to 2014/68/EU Pressure Equipment Directive (PED) EN 13445 Annex C for long-term storage of cryogenic liquified gases under pressure.

Ambient air vaporizers require no external source of energy and enable vaporization through the exchange of heat with the surrounding air. The liquefied gas is vaporized and warmed to almost the surrounding temperature, and finally led to the users in its gaseous state. The vaporizers are for: Oxygen, Nitrogen, Argon, Carbon Dioxide, LNG, Nitrous Oxide.
