Oxygen Generators
To supply oxygen gas separated from compressed air. Main features:
- Compressed air pressure: min.
6 bar
- Purity of produced oxygen: 90-95 %. The remaining gas is argon.
- Pressure of produced oxygen: 4-5 bar.
- Volume of oxygen produced:
- with a single pair of adsorbers: from 0,5 m3/hour
to 6 m3/hour
- with more, than one adsorber pairs: up to 120 m3/hour.
This case, adsorber pairs are connectedd paralelly to increase the
capacity of the generator.

Automatic operation
Generators are controlled by Siemens microprocessor based controllers
(PLC). Control circuitry operates with 24 V DC. Its power consumption
is only 40 W.
Generators automatically stop and start, based on the pressure of
oxygen buffer tank. If the generator was not in operation for a longer
period of time, the generator performs a self-cleaning cycle at
startup.
Maintenance means only periodical check of compressed air filters - or,
if the pressure drop is too high on the filter, the filter cartridge
shall be replaced. The pressure drop is shown by a differencial
pressure indicator.
Modular design - possibility to
further expansion
Oxygen generators are
designed as modular systems. The electronic and pneumatic control of
each generator (from O-2 and larger modules) can operate with more than
a single pair of adsorbers. Thus, if the need for oxygen gas
increases after the installation of a oxygen generator, the produced
volume can be simply increased by adding new pair(s) of adsorbers at
modest costs. The old and new adsorbers will operate paralelly after
the expansion.
It shall be considered, that only that adsorber module can be
used at expansion, that has been installed previously. For
example, a O-4 generator can be expanded by adding an additonal O-4
pair of adsorber, reaching 8 m3/hour production volume.

Oxygen
generators are frequently used for high temperature flame - for
welding, flame-cutting, glass melting and for many other
applications.
