French army uses PSA systems, which concentrates the content of oxygen in the air, especially for OBOGS (On Board Oxygen System) to provide oxygen to the pilots of fighter jets or the crews of military transport aircraft. Next purpose of this technology, developed by Oxymat and Air Liquide Advanced Technologies, can now fulfill a new need: that of military field hospitals for the autonomous production of oxygen for medical use.
For the army, oxygen is essential to the intensive care and anesthesia of the wounded in combat and it is needed in large quantities and consistent quality. In emergency situations, the use of bottled oxygen is not the best solution because the quantities are quickly depleted and logical delivery is restrictive. That is why French Military Health Service has long been looking for alternative solutions to supply gas cylinders. One of them is to independently produce unlimited oxygen on site, in field hospitals.
History of project started in 2006 when French army decided to launch a tender for oxygen generation modules. Our solution applied and won.
A total of three years was required for competitive dialogue, the design and manufacture. Consecutive tests in extreme temperatures (from -32°C to +55°C), humidity (from 40 to 90% of humidity), altitude (2,200 m at the Alpe d'Huez) and of course other special conditions prepared by army.
Head of project add: “It was a substantial challenge. The module had to withstand the toughest of conditions: sand storms, extreme weather, air, sea and off-road transport, etc. It also has to meet strict security requirements”.
French army is equipped with three Oxymat/Air Liquide Advanced Technologies containers at this moment. First of them is deployed in real operational situation - based in field hospital in Afghanistan.
Following containers, with serial numbers 4 and 5 are finished in our production facilities and will be handed over in few weeks.

Essential parameters:
- 2x 7,5 m3/h - two complete and independent lines, i.e. 2x O60x2 3-column PSA system
- Purity 93% ± 1%
- Housing in standard 20-foot ISO container (6,1 m)
Container PSA solution for so demanding customer like French army is, was such a remarkable technological challenge. A challenge, which should also address many of the humanitarian needs of international NGOs…
