Oxygen Gas Plants

Our Oxygen Gas Plants are engineered to be safe, economical, and exceptionally
power-efficient — making them ideal for continuous industrial operation.

Key Features

Medium Operating Pressure Medium Operating Pressure Oxygen Plants operate at just 32–35 kg/cm², significantly reducing energy consumption
Cryogenic Liquid Oxygen Pump Enables seamless cylinder filling of dry gaseous oxygen at desired pressure of up to 200 kg/cm²g (Bar)
Integrated Molecular Sieve Dryer Removes moisture, CO₂, acetylene, hydrocarbons, and other impurities.
Fast Start-Up Requires only ~8 hours to resume production after the defrost cycle.
Dual Production Capability Simultaneously produces high-purity Oxygen (up to 99.6%) & up to 99.9999% Nitrogen without additional cost.
Compact Layout Complete plant and cylinder filling station can be accommodated within a compact footprint.

Performance Advantages

1.0 kWh per m³ of oxygen for 250 cu.m/hr capacity and above, under normal continuous operation — one of the lowest energy profiles in the industry.

Output typically exceeds rated capacity due to efficient design and high-quality materials

Super-efficient expansion engine ensures rapid cooling, reduced startup time, and long-term power savings.

How It Works (Cryogenic Air Separation)

Atmospheric air is compressed, cooled, purified through molecular sieves, and passed through heat exchangers. A portion flows through an expansion engine to generate refrigeration. Liquefied air then enters distillation columns for separation, where oxygen and nitrogen split based on boiling points. Waste nitrogen and product oxygen are routed through heat exchangers for energy recovery before final delivery or cylinder filling.

Benefits of Oxygen Gas Plants

99.6% purity suitable for medical & industrial use
Long-term cost savings with superior ROI
Power-efficient cryogenic processing
Independence from external LOX/LIN supply chains
Highly customizable capacities (40 to 1500+ m³/hr)
