| Proven Technology
Balston Monobed and Dual Bed Nitrogen Generators
produce up to 99.99% pure, compressed nitrogen at
dewpoints to -70°F (-21°C) from nearly any compressed
air supply. The generators are designed to continually
transform standard compressed air into nitrogen at safe,
regulated pressures without operator attention.
How the Technology Works
Balston PSA Nitrogen Generators utilize a combination of
filtration and pressure swing adsorption technologies.
High efficiency prefiltration pretreats the compressed air
to remove all contaminants down to 0.1 micron. Air
entering the generator consists of 21% oxygen and 78%
nitrogen. The gas separation process preferentially
adsorbs oxygen over nitrogen using carbon molecular
sieve (CMS). At high pressures the CMS has a greater
affinity for oxygen, carbon dioxide, and water vapor than
it does at low pressures. By raising and lowering the
pressure within the CMS bed, all contaminants are
captured and released, leaving the CMS unchanged.
This process allows the nitrogen to pass through as a
product gas at pressure. The depressurization phase of
the CMS releases the absorbed oxygen and other
contaminant gases to the atmosphere.

| Savings and Convenience |  |
|
| The Balston PSA Nitrogen Generators completely eliminate the inconvenience and the high costs of nitrogen Dewars, bulk nitrogen supplies, and cylinders. There is no need to depend on outside vendors for your nitrogen gas supplies. The hassles of changing dangerous, high pressure cylinders, and interruption of gas supplies are completely eliminated. The Balston PSA Nitrogen Generators offer long term cost stability eliminating uncontrollable vendor price increases, contract negotiations, long term commitments, and tank rentals. Once the Generator is installed, a continuous nitrogen supply of consistent purity is available within minutes from start-up. | ||

Easy to Operate and Maintain
Installation consists of simply connecting a standard compressed air line to the inlet and connecting the outlet to a nitrogen line. Plug the electrical cord into a wall outlet, and the unit is ready for trouble-free operation. This system is designed to operate 24 hours per day, 7 days per week. Once the system is operating, it requires little monitoring. The only maintenance involves changing the coalescing prefilter cartridges and final sterile air filter periodically. The PSA towers do not require any maintenance. An oxygen monitor to measure the oxygen concentration of the nitrogen stream is available as an option. An audible alarm signals high or low oxygen concentrations (determined by the application). The oxygen analyzer is supplied with alarm relay outputs which may by used to signal a remote alarm, open a backup supply or the process stream, or close the process flow for protection of downstream equipment or processes. | |
