OXYGEN GENERATORS

 

All systems are available at 95% or 99% purity levels.

Specifically designed to produce Low Pressure (50

- 70 PSI) Oxygen for a wide range of medical and 

industrial applications.

Models for every application, with gas flows from 20 SCFH

/0,5 m3/h to more than 3,000 SCFH/85 m3/h.

With the addition of an Oxygen High  Pressure 

Compressor and storage cylinders ("K" or "T")

Oxygen reserves can be created for

system backup and for distribution to other locations.     

Orion Oxygen Generation systems can pay for themselves

within months  by producing low-cost oxygen for use on site

combined with the sale of surplus oxygen to outside users                   99% Oxygen Generating System  with filling station

at competitive prices. 

PSA technology is especially effective for the producing of 

low cost Nitrogen and Oxygen on-site and on-demand.

 

The Generation of Oxygen using PSA Technology

 

The air we breathe contains roughly 78% nitrogen, 21 % oxygen, .9% argon.  The balance is comprised of other gases.  The oxygen is separated from the air using PSA Technology. 

The process centers around a molecular sieve known as Zeolite.   At high pressures the sieve adsorbs nitrogen, and at low pressures it desorbs or releases nitrogen. PSA  generators consist of two tanks filled with sieve. As high pressure air (about 70 psi) is introduced into the first tank, it passes through the sieve and nitrogen is adsorbed. The remaining oxygen and argon are piped to a buffer or storage tank.

Just before the first tank becomes completely saturated with nitrogen, the feed air is redirected to the second tank which then repeats the above process. While this is happening the first tank is then vented to atmosphere allowing the nitrogen to escape from the sieve. To complete the readiness of the first tank, a small amount of the oxygen is used to purge it.This process is repeated over and over again producing a continuous flow of oxygen. When clean and dry air is used and under otherwise normal conditions, the sieve will last indefinitely.

The production volume of a PSA generator is also dependent on the oxygen purity required. For example, a generator can produce significantly more oxygen at 90% purity than it can at 96%, with a relatively small increase in feed air. By means of a PLC or some other timing-based controller, the user may straightforwardly manage the swing cycles on any oxygen generator. Purity and flow levels can be selected and optimized to match requirements.

 

ADVANTAGES

1.     On-site oxygen production at lower cost – typically 25% to 33% of the cost of liquid Oxygen.

2.     Output oxygen is very dry with a dew point around -60°C

3.     Low running cost – OGI generators have low power requirements.

4.     Instant availability – Oxygen gas is produced immediately at start-up.

5.     Automatic control -  The OGI system works automatically upon start-up.

6.     Compact design. - The OGI system has a small footprint

7.     Oxygen is produced, on site and on demand.
