GRASYS is the CIS leader and one of the European largest manufacturers of industrial plants designed for gas production and separation. GRASYS offers equipment based on all the three existing technologies of gas separation: membrane, adsorption, and cryogenic ones.

GRASYS is involved in the development and manufacture of high-technology nitrogen and oxygen production systems — nitrogen and oxygen plants, nitrogen and oxygen mobile stations, nitrogen generators and oxygen generators, as well as other types of equipment.

GRASYS also implements an «on-site» scheme of gas marketing, where a plant, owned and maintained by the Company, is installed at a Customer site.

The invariably high quality of products, integration of the most advanced technologies and  individual approach to each customer are the key principles underlining the development of our Company. Over a several-year span, GRASYS, adhering to its principles, has managed to become the CIS leading manufacturer of air separation plants and stations for nitrogen and oxygen production, nitrogen fire-fighting plants and other gas separation complexes. Today, GRASYS is a high-tech company focused on a continuous improvement of the equipment produced and services rendered.
