High Purity Nitrogen Generator / Nitrogen Generator Unit Used In Aero Space Industry

Product Description:

1)General features of the unit:

·The equipment consists of air compressor, buffer tank, refrigerator dryer, pre-filter units, activated carbon filter, PSA towers , buffer tanks and its electrical control cabinet. Each unit is connected by pipes, and assembled in one steel pallet.

· The purity of N₂ can reach 99.9% - 99.99%.

2)Excellent operation performance:

· The equipment has the perfect function, for instance, recording the nitrogen purity and flowrate and alarm history etc.

· The unit can automatically running, no need extra labour force.

3) High Quality:

· Company has the culture of quality first.

· Adopting decent quality spare parts always. For instance, we choose high quality valve and its service life reach up to one million times.

· Quality inspection activities is carried out in the whole manufacture process.

· We always test every equipment and carefully adjust every elements in a good condition before shipping.

Air is composed of 78% Nitrogen and 21% Oxygen. PSA Nitrogen generation technology works on the principle of air separation by adsorbing Oxygen for getting Nitrogen.
Pressure Swing Adsorption (PSA Nitrogen) process comprises of 2 tanks filled with Carbon Molecular Sieves (CMS). (see image below).
Step 1: Adsorption
Pre filtered compressed air is passed through one CMS filled tank. Oxygen is adsorbed by the CMS and nitrogen comes out as the product gas. After some time of operation, the CMS inside this tank gets saturated with Oxygen and can no longer adsorb.
Step 2: Desorption
When the CMS is saturation in the one tank, the unit automatically switches nitrogen generation to the other tank. The waste gas (oxygen, carbon dioxide, etc.) is discharged into atmosphere.
Step 3: Renew
In order to regenerate the CMS in the tank, part of the Nitrogen produced by the other tank is purged into this tank. This makes quick CMS regeneration and make it available for produce nitrogen in the next cycle.
The above process cycle ensures continous supply of the Nitrogen.
