Specifically designed to produce Low Pressure (50 - 70 PSI) Oxygen (choice of 95% or 99% purities) for a wide range of medical and industrial applications. All operations are simple and optimized for maximum system operation. All models are available in 95% or 99% Oxygen purities. 

With the addition of an Oxygen High Pressure Compressor and storage cylinders ("K" or "T") you can create Oxygen reserves for system backup or for distribution to other locations. Oxygen Production systems can easily pay for the cost of the entire Oxygen Generator system within months by allowing you the opportunity to sell off excessive Oxygen to outside users at very attractive prices

PSA technology is especially effective in producing low cost Nitrogen and Oxygen on-site and on-demand.  For example lets look at generating oxygen using PSA techniques. The air we breathe contains roughly 78% nitrogen, 21 % oxygen, .9% argon and the balance is 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, feed air is redirected to the second tank which then repeats the above process. The first tank is then vented to atmosphere which allows the nitrogen to desorb or release from the sieve. To complete the regeneration of the first tank, a small amount of the oxygen is used to purge it. This process is completed over and over again until the demand for oxygen is met. Under normal operating conditions, which includes the use of clean dry air for separation, the sieve will last indefinitely. Productivity of a PSA generator is dependent on the oxygen purity required. A generator can produce significantly more oxygen at 90% purity than it can at 95.4%, with a relatively small increase in feed air. By means of a PLC or some other timing based controller, it is practical on larger generators for the user to change the swing cycles. Purity and flow levels can be selected and optimized based on changing demand variables.
