PRISM® Nitrogen Membrane Systems
High-Capacity Series
Air Products’ family of High-Capacity Membrane Nitrogen Systems meets the needs of
large-volume customers. The systems use a
proprietary high-capacity membrane fiber
developed to minimize 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 highvolume requirements up to 70,000 scfh with a
range of purities up to 99.9%.
Technology at Work the World
Over
The heart of Air Products’ 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 fiber membranes
that selectively remove oxygen, water vapor,
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.
Large-volume users can benefit from the ability of the High-Capacity
Series to significantly reduce overall power and nitrogen costs
compared to traditional systems.
