Mobile oxygen stations

Grasys offers its customers serial mobile oxygen stations for cylinders filling with the rated throughput of 100 cylinders per day. Grasys also produces custom-designed oxygen stations according to customer’s technical assignment.

Mobile oxygen stations are containerized air separation complexes designed for 99% oxygen production from air and oxygen cylinders filling. Stations are installed in standard block containers with the dimensions of 2,500×2,500×6,000 mm which enables their simple installation on chassis and delivery to the target work location.

The station container is fitted with the positive ventilation system and the heating system. This ensures convenience of station operation in various climatic zones. No special foundation is required for station installation. The only requirement for station operation is the supply of 380 V electric power with no other utilities required for oxygen production.

Advantages of Grasys mobile oxygen stations

  • Quick deployments of oxygen production in cylinders
  • Advanced oxygen generator and improved adsorbent properties
  • Highly reliable imported compressors with the lifetime exceeding that of Russian analogs
  • High level of safety
  • Up-to-date ventilation and heating system
  • Low operating costs
  • State-of-the-art intelligent control system GRASYS Intelligent Control-7 with the manual, automatic and remote control options

General information

The undoubted advantage of Grasys oxygen stations is the system quick startup and shutdown which takes no more than 20 minutes. The prompt process stabilization enables the customer to arrange for oxygen production on an as-needed basis. This is a dramatic improvement as compared with cryogenic plants set to operate in the round-the-clock mode.

The array of applications of oxygen plants is extremely wide and includes such areas as autogenous oxygen production (apart from automated metal cutting); oxygen generators are also helpful in the silicate, pulp and paper, food and pharmaceutical industries, in fish farming, sewage treatment and ozonation plants feeding, solid waste incineration and in medicine.

Stations are intended for oxygen production from atmospheric air on the basis of the proven pressure swing adsorption (PSA) technology. Mobile oxygen stations have the superior performance characteristics — combining exceptional reliability and a moderate cost of product oxygen.

The principle of Grasys mobile oxygen stations operation is based on the adsorbent materials capability of selectively adsorbing nitrogen molecules and impurity gases contained in atmospheric air while allowing oxygen molecules to freely pass through. All adsorbents used in oxygen generators undergo certification and inspection in Russia which guarantees operating reliability of systems and high quality of the product.
