1. Air Compressor: Air is compressed at a low pressure of 5-7 bar (0.5-0.7mpa)
2. Pre Cooling System: Cooling the temperature of air to around 12 deg C.
3. Purification of Air By Purifier: Twin molecular Sieve driers
4. Cryogenic Cooling of Air by Expander: Turbo expander cools the temperature of air below -165 to-170 deg C.
5. Separation of Liquid Air into Oxygen and Nitrogen by Air Separation Column
6. Liquid Oxygen/Nitrogen is stored in a Liquid Storage Tank
