Use of nitrogen is growing due to its wide variety of applications creating inert atmosphere, carrier gas, blanketing, purging, packing, filling, plastic moulding, etc) covering a broad spectrum of industry & research laboratories. It is also used in tank farms, mobile tankers & containers, agricultural products storages, tyre filling, etc.

In most applications, the N2 pressure required is less than 6 bar. Despite this, high pressure N2 cylinders are commonly used as source of N2, whose handling is quite hazardous & risky. A better option would be to produce your own low pressure N2

How do I produce my own N2 ?

Low pressure N2 can be produced by separating oxygen and nitrogen in air by using the pressure swing adsorption (PSA) process. Dry & oil-free compressed air produced in our Compressed Air System enters the PSA Nitrogen Generator and is first stored in the Dry Air Receiver from where it enters the PSA System. Here the oxygen is adsorbed by the Carbon Molecular Sieves and nitrogen comes out as a product gas. The N2 enters the Surge Vessel where its purity is stabilized before it is sent to the Nitrogen Vessel and then drawn for use. Necessary measurement and control devices are incorporated to make the N2 Generator fully automatic as well as to ensure that only pure N2 goes to your User equipment.

What are the benefits of producing your own N2 ?

(a) You save lot of money – cost of N2 from Generator is just 20% to 40% of N2
     from cylinder.

(b) It gives N2 of better and consistent purity than that available from cylinders, which are
     known to have O2 varying from 0.5% to 4% ( actual measurements taken by us). In our
     Generator, continuous online O2 measurement is available.
(c) Elimination of accident risk likely due to handling of N2 cylinders as well as possibility of
     excess O2 in cylinders.
(d) Tax savings due to depreciation.

What size of N2 Generator should I use ?

To work out the capacity of N2 Generator best suited to your needs, please provide following information:

1. No. of cylinders used / day (please indicate working hours / day )
2. If the usage is intermittent, please give details.
3. Landed cost per cylinder (required to carry out an accurate cost-benefit analysis)
4. Brief description of applications.

Some of the applications where our N2 from our Generator has proved to be economical and beneficial: 

Analytical Instruments used for Research & QC such as LCMS, Turbo Vaporizer (sample concentrator), GC, Mass Spectroscopy, etc.	Blanketing, purging, filling, transfer, cleaning, micronizing, packing, etc in manufacture & storage of chemicals, bulk drugs, APIs, food products, etc. *
Inert atmosphere for soldering, brazing, melting, heat treatment, etc.	Inert atmosphere in food containers, tankers, fruit & vegetable storage, etc
Tyre filling
