• the device comprises equipment requiring maintenance and / or manipulation arranged in front;
• the device comprises a gas inlet 10 to a first adsorber and an outlet 9 of gas from a second adsorber located on the same side of the device.
• Pe size refers to the outside diameter of pipes without considering equipment, such as valves, that can be incorporated into pipes.
• the equipment is arranged in front “means that the equipment is arranged facing the user in such a way that he can easily access it.
• Equipment requiring maintenance and / or handling is of the type valves, valves, valves, instrumentation, pressure reducer, ...
• the present invention also relates to the use of the purification device according to the invention for producing air supplying a cryogenic air separation unit.

• the purification device according to the invention allows the reduction of manufacturing costs, minimizes the development time of new work implementing a purification device, and provides greater flexibility of adaptation to new materials and / or new regulations.
• the standardization of the purification device simplifies the understanding of the processes and reduces the number of components.
• the purification device according to the invention can adapt to different regulations and building codes of countries in the world.
• the purification device according to the invention also significantly reduces the installation time, currently, with a purification device comprising a skid. Indeed, there is more connection between the bottle and the skid to achieve: the purification device according to the invention is a pre-assembled subassembly ready to be connected. Access to equipment for maintenance facilitates on-site interventions. All valves, valves and pipe elements are aligned front to minimize handling and associated risks. On a purification device comprising a skid, the replacement time of a valve may exceed the day due to access difficulties.
