◆PSA NITROGEN GENERATORS

A PSA (Pressure Swing Adsorption) nitrogen generator is an apparatus than gains pure oxygen from the air.
Compressed outside air is brought into one of the two vessels. In here the oxygen will be adsorbed bye the carbon molecules, and nitrogen leaves the vessel. While one vessel is used for adsorption, the second vessel is regenerated by reducing the pressure in a controlled manner. Hereby the adsorbed oxygen molecules are discharged to the air. When the first vessel is saturated, the process direction is switched. Now the first vessel is regenerated, while the second one is adsorbing. This principle is called Pressure Swing Adsorption (PSA).

The advantages of a PSA nitrogen generator are:
• Reliable operation:a relatively simple process and thus reliable. A technology
  that has proven itself.
• Production of pure nitrogen with less rest-oxygen.
•Energy efficient. The only system with a pull down from 97 ~ 99.99% oxygen as
 well as very economical in relation to energy consumption.


The PSA nitrogen generator is standard equipped with a PLC operating system, but can also be equipped with a microprocessor. The microprocessor type can be operated by the control panel on the front of the PSA, but can also be operated by PC if an analysing system is connected.
