Profile match
Air Liquide is a French industrial gases company founded in 1902 that supplies oxygen, nitrogen, hydrogen, argon and specialty gases to industry, healthcare and electronics manufacturers. Industrial gases is an unusually attractive business: gases are expensive to transport relative to their value, so suppliers build plants next to customers under contracts running fifteen years or more, which makes local positions close to unassailable. Headquartered in Paris and listed there, it is also one of the largest producers of hydrogen and supplies the ultra-pure gases semiconductor fabs consume in enormous quantities.

We are everywhere in your daily life and you don’t see it ! With our entity Air Liquide France Industrie, we participate of our customer's innovative development applications : the bubbles of your soda, the chip of your smartphone or the reduction of polluting emissions,

Air Liquide France Industrie brings together the production and marketing of industrial gases in France with four complementary business lines : Large Industry, Industrial Merchant, Electronics and Hydrogen. The subsidiary has 2,400 employees at 58 sites across the country and serves more than 200,000 customers, from the artisan to petrochemical manufacturers, from analytical laboratories to semiconductors and metallurgy.
