Product Features

1. Full Automation

All systems are designed for un-attended operation and automatic Nitrogen demand adjustment.

2. Lower Space Requirement

The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory.

3. Fast Start-up

Start-up time is about 30 minutes to get desired Nitrogen purity. So these units can be switched ON & OFF as per Nitrogen demand changes.

4. High Reliability

It’s very reliable for continuous and steady operation with constant Nitrogen purity. Plant availability time is better than 99% always.

5. Molecular Sieves Life

Expected Molecular sieves life is more than 10-years i.e. whole life time of Nitrogen plant. So no replacement costs.

6. Low investment and energy consumption

7. Simple operation and maintenance

The normal purity Nitrogen system (97%~99.999%) is consisted of equipment as followings:

(according to user different requirements, may has changes)

It has 2-vessels filled with Molecular sieves. Clean compressed air at 30º C temp is passed through

1-vessel and nitrogen comes out as product gas. The other vessel is depressurized to atmospheric

pressure and purged with little quantity of Nitrogen coming out from other vessel. This regenerates

Molecular sieves for use in next cycle. Thus 2-vessels keep cycling alternately in Nitrogen

production and Regeneration making Nitrogen gas available continuously. These units are designed

and supplied for 98% to 99.999% (Max) Nitrogen purity.

• From PSA design Nitrogen pressure is available directly up to 5 Bar (A) without need of booster

compressor. So this design is preferred for Low and medium pressure Nitrogen requirements.

• It’s very simple in construction and very easy in maintenance and more popular for most

Oxygen requirements.
