Oxygen or nitrogen can be produced from compressed air on the customer’s site using on-site generators or systems.
Systems based on PSA, VSA or membrane technology (known as oxygen and/or nitrogen generators) are the most practical option when you need large volumes of gas, and high purity levels are less important.
On-site systems are also used by the food industry to produce small amounts of UHP gas, for example to produce nitrogen for food packaging.
PSA = Pressure Swing Adsorption
VSA = Vacuum Swing Adsorption
