More companies are becoming aware of the
huge savings being made from generating
nitrogen over expensive bottled and bulk stored
liquid nitrogen. PCM offers two technologies:
HOLLOW FIBRE MEMBRANE
Hollow fibre membrane technology – used
for the generation of nitrogen or oxygen
enriched gas from compressed air. Membrane
technology is efficient for high volume lower
purity applications. The basis of the technology
is thousands of hollow fibres. The walls of these
fibres selectively diffuse oxygen.
PCM offers nitrogen generator solutions that
produce up to 99.5% pure, commercially sterile
nitrogen at dew points to -50°C from any
compressed air supply.
With flow rates up
to 11,400 scfh, this
the need for costly
gas cylinders and
liquid storage tanks.
A complete package
with pre-filters, carbon
filter and O2 analyser
is available as standard.
We can eliminate
due to ‘bad’ or empty
cylinders and offer a
safe and reliable supply.
We offer a design, installation and maintenance
package unique to your application. This
technology is becoming increasingly used
for industrial fire suppression, high pressure
product testing, plasma and laser cutters, food
packaging and chemical blanketing.
PCM offers the know-how in the design and
manufacturing of nitrogen generation plants by
Pressure Swing Adsorption (PSA).
We are in the forefront of this technology and
have the flexibility to provide the right packages
to meet all customer requirements.
The PSA systems produce nitrogen to capacities
of up to 99.999% and ideally suited for the
higher purity, high output demands.
How it works: These are PSA (Pressure Swing
Adsorption) nitrogen generating systems. Each
unit has two adsorber beds filled with a carbon
molecular sieve (CMS). Compressed air enters
one end of a bed. While the smaller oxygen
molecules are adsorbed by the CMS, the larger
nitrogen molecules pass through the sieve and
are stored. Once the tube is saturated with
oxygen, the first adsorber releases the gas, and
the second adsorber starts the process over
