standard oxygen cylinder filling

95% Pure Oxygen Generator with Cylinder Filling: Hi-Tech has a wide range of Oxygen filling stations used for filling cylinders of any size up to 200 bar. The filling capacity ranges from 2 to 200 cylinders per day.

The system can be set up to fill the hospital pipeline directly and use the filling ramp as a backup system. Oxygen cylinders can be filled simultaneously or during hours with low consumption.


  • No Raw Material
    There is no Raw Material Required to produce Industrial/Medical grade Oxygen, as plant uses air from atmosphere to separate oxygen from Processed air
  • Quality & Durability
    Each Generator is Analyzed & Tested over Latest CFD Software for dynamic loading in order to ensure Quality product with SMART Productivity of Oxygen Gas.
  • Oxygen on demand
    Production of oxygen at the specified flow and purity for a short time of demand by simple push button.
  • Energy efficiency
    The PSA process is characterized by low specific energy consumption. Easy partial load operation PSA Generators are fully automatically adjusted to the actual product flow requirements and operate in an energy-saving partial load mode.
  • Platform Mounted
    Generator is supplied Pre-piped over a platform in order to cuts down installation time, only to connect compressor line and plant is ready to use
  • High availability
    PSA Generator provide supreme availability by using reliable components such as Screw Compressors proprietary switching valves.
  • Fully automatic operation
    The PLC based control system with its sophisticated software controls purity and flow by adjusting the cycle time automatically.
