Oxair’s nitrogen membrane systems supply a range of volume requirements up to 5,000 M3/hr (170,000 SCFH with a range of purities up to 99.9%), delivering a constant flow of high purity nitrogen gas.

The Australian-based company has released its new PRISM® membrane system, which suits larger nitrogen demands, especially in remote locations such as oil platforms and chemical plants.

The technology can be used directly by the end user on demand, eliminating the need for cylinders, dewars or tanks.

“Companies have different demands but need to adapt to a dynamic marketplace and squeeze every cent out of production processes. Ensuring a constant supply of nitrogen is a crucial requirement for many industry sectors. Nitrogen membrane generators can safeguard supplies and help operators become self-sufficient in this important gas,” said James Newell, CEO of Oxair.

Generating nitrogen on site offers a flexible, stable supply line and is more environmentally friendly, making redundant the needs to swap full for empty cylinders, as well as providing other benefits such as easy installation, fast start-up, unattended operation and cost savings.

Suitable for a range of industry sectors, onsite nitrogen membrane generators from Oxair can be customised to provide an efficient supply for a variety of volumes, purity requirements and usage patterns, especially if the demand fluctuates.

Onsite gas generation, involving membrane technology, use compressed air forced through a polymeric hollow fibre to selectively permeate oxygen, water vapour, and other impurities out of its side walls while allowing nitrogen to flow through its centre and emerge as high purity nitrogen gas.
