Air Separation Plant

Air separation plants are usually big plants meant to generate oxygen and nitrogen in both formats liquids as well as gases. The machines are tested several times by customer care executives before making them available for shipment. Manufacturing process is also supervised by seniors to bring products without error. Quality and testing team runs the plant and ensures that every part of it performs exceptionally well. Once the management gets approval from different concerned departments, it approves shipping and sanctions engineer for commissioning, erection and installation at client site.

Air separation plants, alike other plants of our organization; come in different sizes ranging from 50 m3/hr to 10000 m3/hr. And the purity of each plant is same, which is upto 99.7% oxygen and 99.99% nitrogen. Such a purity is sufficient for different medical and industrial applications. Components of our organization are also taken from reputed and known companies to ensure smooth performance for long time. However, warranty and guarantee services are also provided. Our machines do not carry reciprocating parts so no need to change spare parts on regular basis.

Features of our air separation machines and equipment :

  • Cost effective
  • Latest technology
  • No reciprocating parts
  • Minimum electricity
  • Smooth performance
  • Ready to install
  • Easy to run
Air Separation Plant

Cost of an air separation unit depends upon company to company. Our plants are cost effective and technologically very advanced. On the other hand, components of our company are also reliable and long lasting as we take them from reputed companies. Sometimes we also offer discount in order to finish our buffer stock. The discount may range from 10 to 40% depending upon the number of plants we have in buffer stock. Our payment terms are also very easy and client friendly. We ask them to make the advance payment of 40% on the time of booking and rest 60% on the time of shipping.

If you want more information about the plant like how does an air separation plants/units work, etc. You should contact our customer care executives. Even they can provide you technical quotation as per your particular capacity demand. You can also see the air separation unit process flow diagram to understand functioning process. Once they are installed, they perform smoothly for years without malfunctioning. Our engineers have years of experience in the field of designing, manufacturing, commissioning, erection and installation of plants.

Generation process of oxygen and nitrogen through air separation plants :


Compression of atmospheric air by air compressor : Atmospheric air is sucked through air compressors. The air can be compressed at such low pressure only by advanced and rotary compressor.

Cooling of air at pre cooling system : In the pre cooling system, the compressed air needs to be cooled down to around 12 degree centigrade. Thereafter, it is sent for the purifier.

Purification of air by purifier : The air goes inside a purifier comprising of twin molecular sieve driers, working alternatively. The molecular sieves alleviate the carbon dioxide & moisture from the processed air before the air enters air separation unit.

Cooling of air by turbo (expander) :The air has to be cooled to sub zero temperatures for liquification & the cryogenic refrigeration. The cooling is offered by highly efficient turbo expander, which cools the air to temperature almost below -165 degree centigrade to-170 degree centigrade.

Filling of oxygen/nitrogen in the cylinders :The final product in the form compressed oxygen/nitrogen goes to the high pressure oxygen cylinders at 150 bar or upto higher as required.
