Hidden values
Gases have many different properties: they can speed up or slow down processes, heat, refrigerate, alter or preserve products. They are "invisible aid factors" developing services with an immeasurable value for human kind and for the environment: they keep food fresh, help people to breathe and are used to clean and improve the quality of water for creatures that live in aquatic environments.
They are constantly present in the maintenance of health and the improvement of quality of life.
