Oxair Gases’ family of High-Capacity Membrane Nitrogen Systems meets the needs of
large-volume customers. The systems use a proprietary high-capacity membrane fibre
developed to minimise your electrical power consumption. Engineered for fast installation,
low maintenance, and simple operation, these systems are an ideal supply alternative for a
wide range of applications, with significant operational savings over liquid nitrogen
tanks. Models are available to supply your high-volume requirements up to 70,000 scfh with
a range of purities up to 99.9%.
Technology at Work the World Over
The heart of Oxair Gases’ High-Capacity Systems is the unique membrane technology
pioneered by Permea, Inc., a wholly-owned subsidiary of Air Products and a leading
innovator in gas separation technologies.
These systems’ specially-engineered separation modules contain hollow fibre membranes
that selectively remove oxygen, water vapour, and carbon dioxide from compressed air to
efficiently produce nitrogen. Purity and flow rate can be adjusted to suit individual
requirements. Thousands of systems using our proprietary membrane technology are in
operation at sites around the world. Membrane systems generate nitrogen at significant
savings over liquid nitrogen. The PRISM High-Capacity Systems can optimise costs over
traditional membrane systems.
Designed to Meet Your Needs
- Nitrogen purity adjustable from 95.0 to 99.9% for greatest flexibility and cost savings.
- Expansion capability allows system to accommodate increased volume requirements.
- Compact, weatherproof housing allows operation at low ambient temperatures.
- Floor-mounted configuration requires no special foundations.
- Removable panels provide easy internal access for system maintenance.
- Simple design with few moving parts means easy operation, minimal maintenance, maximum
reliability.
- Advanced PLC control system enables remote operation and monitoring through optional
telemetry (Series 5000).
- Internal heating facilitates easy on/off.
- Automatic shutdown during low demand saves power.
- High-spec construction available for demanding environments.
