OXYGEN is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element and oxidizing agent that readily forms compounds (notably oxides) with most elements.
By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standardized conditions for temperature and pressure, two atoms of the element bind to form dioxygen, a diatomic gas that is colorless, odorless, and tasteless, with the formula O
There are basic Three Production technologies for Oxygen Production

Cryogenic Oxygen Nitrogen Plant

A cryogenic plant uses fractional distillation of liquid air technique to separate Oxygen and Nitrogen due to their boiling point difference. The Oxygen and Nitrogen thus obtained is directly filled to a cylinder with the help of  Separate pumps.

PSA Based Oxygen Plant

PSA Oxygen Plant use pressures swing adsorption method for separating oxygen from air.the system operates at ambient temperature with working pressure up to 215 bars(G).

VPSA Based Oxygen Plant

VPSA Oxygen Plant uses Vacuum Pressures swing adsorption method for separating oxygen from the air.The system operates over ambient temperature with working pressure up to 1 bars(G), higher pressure is available with separate compressor

Military Grade PSA Based Oxygen Plant

Oxygen Plant based on pressure swing adsorption (PSA) Technology used for charging cylinders/bottles up to a high pressure of 2900 PSI for MIlitary Defense & first responders.

Medical Oxygen Generator

Medical Oxygen generator uses Raw free atmospheric air to produce medical grade oxygen, available in various capacities ranging from 1Nm3/hr to 500Nm3/hr
