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

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)
