Why N2 Generator?

itrogen is an odorless and colorless gas used as a key ingredient of fertilizer. Liquefied nitrogen is also used for quick freezing in regeneration technology, medicine and research. Unlike oxygen, nitrogen does not have any reactivity so that it is one of the most commonly used industrial gases.
Nitrogen is leased or provided by a third party through a nitrogen tank or small high-pressure container or internally produced and used, using compressed air. GSA N2 Generator adopting pressure swing adsorption (PSA) technology is the best choice to use high-quality nitrogen anytime in a stable fashion at the lowest costs.

Applications

• Electricity and electronics

• Food and beverage packaging

• Pharmaceuticals

• Chemical processing

• Power plant

• Laboratory

• Heat treatment

• Blazing

• Fire prevention

• Oil refining

• Metal working

• Laser cutting

Positive Effect

Installed on the site and immediately produces nitrogen from compressed air
No production setbacks from an issue in nitrogen refill, delivery or supply
Reduction of operating and maintenance costs
Able to design diverse purity according to customer needs (95% to 99.999%)

N2 Generator

The N2 generator is operated under the following mechanism: Nitrogen is supplied by separating oxygen from compressed air, using desiccants filled in two absorption towers.

Compressed air including both nitrogen and oxygen supplies nitrogen by adsorbing oxygen while passing through a carbon molecular sieve (CMS) layer which has micro pores filled in the absorption towers.

The two absorption towers repeat pressurizing, absorption, depressurizing and cleaning by taking turns and supply nitrogen consecutively.
GSA’s pressure swing adsorption (PSA)-based N2 generator has a specially designed distributor at the bottom of the absorption towers so that it is able to supply high-quality nitrogen which meets customer needs in a continuous and stable manner. In addition, the use of durable valves enables stable operation. Since diverse features needed to control the system are supported, settings and operations which meet user needs are enabled.
