These plants are designed for production of liquid and/or gaseous oxygen, nitrogen and argon from atmospheric air based on the low-temperature rectification process.

The plants can be offered as

• Skid-mounted
• Containerised
• Individually assembled

and are designed for partly or fully automatic operation (control system SIEMENS SIMATIC).

The liquid and gaseous products have a very high purity and can be used for medical and industrial application.
