General Description
Grasys manufactures oxygen generation equipment based on well-proven (PSA) and (VPSA) technologies. The operating principle is based on the properties of adsorbing materials to selectively absorb molecules of nitrogen and impurity gases contained in atmospheric air, while allowing oxygen molecules to pass through. All the adsorbents used in the equipment are certified and approved in Russia, which guarantees the reliability of the systems and the high quality of the oxygen produced.
The use of air-separating adsorption oxygen generation plants can reduce the cost of the oxygen produced many times over. The undisputed advantage of these systems, apart from the economic benefits, is their ease of use and maintenance, as well as very high reliability.
Oxygen generation plants are used for a wide range of applications, the most popular being autogenous oxygen (except for automatic metal cutting). Oxygen generators are also used in the silicate,
Grasys offers a wide range of air separation units for oxygen generation, from small mobile units for metal cutting and welding to systems for independent filling of standard oxygen cylinders at 150 atm in the production facility.
Applications
- Raising the temperature in melting and glass furnaces
- Preparation of different chemical compounds
- Reducing sulphur deposits in refineries
- Gas welding, cutting, soldering of metals
- Reducing fry incubation time in fish farming
