Our Oxygen Gas Plants are engineered to be safe, economical, and exceptionally
power-efficient — making them ideal for continuous industrial operation.
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.
The plant is very versatile and can be set for a cycle to produce any one of the following alternatives:

We design and manufacture Oxygen and Nitrogen plants tailored to:
An Oxygen Gas Plant produces high-purity oxygen — up to 99.6%, suitable for both medical and industrial use — for industries such as healthcare, steel, pharmaceuticals, and fabrication. A Nitrogen Gas Plant generates nitrogen up to 99.9999% purity for applications including food packaging, electronics, chemical processing, laser cutting, and oil & gas. Both plants use cryogenic air separation technology, and Sanghi Overseas's design can produce both gases simultaneously from a single system without additional cost.
Sanghi Overseas is an ISO 9001:2015-certified manufacturer with over 1,100 installations across 90+ countries. Its Oxygen and Nitrogen Gas Plants run on cryogenic air separation technology built for power efficiency — as low as 1.0 kWh per m³ of oxygen at 250 cu.m/hr capacity and above — with medium operating pressure (32-35 kg/cm²) that reduces energy consumption compared to higher-pressure alternatives. The company provides complete engineering support from design through commissioning, for both domestic and export projects.
Industries that commonly install Oxygen Gas Plants and Nitrogen Gas Plants include steel, pharmaceuticals, hospitals, chemicals, food processing, electronics, glass manufacturing, fabrication, oil & gas, laboratories, and engineering industries where a continuous supply of industrial gases is essential.
An on-site Oxygen Gas Plant reduces dependence on gas cylinders and removes reliance on external LOX supply chains, lowers operating costs through power-efficient cryogenic processing, provides a continuous oxygen supply at up to 99.6% purity, and can restart in as little as 8 hours after a defrost cycle. Capacities range from 80 to 1,500+ m³/hr, so plants can be sized to actual daily consumption rather than over- or under-building.
A Nitrogen Gas Plant provides an uninterrupted nitrogen supply at purities from 99.9% up to 99.9999% depending on application needs, reduces transportation costs versus cylinder delivery, and is built for stable continuous industrial duty rather than intermittent operation. Sanghi Overseas's design allows nitrogen to be produced alongside oxygen from the same plant at no additional cost, which lowers the total investment for facilities that need both gases.
Yes. Sanghi Overseas manufactures cryogenic air separation plants with dual production capability — simultaneously producing oxygen up to 99.6% purity and nitrogen up to 99.9999% purity from the same system at no additional cost. This integrated design is ideal for industries requiring both gases while maximizing efficiency and reducing operating costs.
Sanghi Overseas offers Oxygen and Nitrogen Gas Plants across a wide capacity range, from 80 to 1,500+ m³/hr, with models available at multiple fixed capacity points in between. Capacities can be customized according to gas purity requirements, production volume, industry application, and future expansion plans.
The plants utilize cryogenic air separation technology: ambient air is compressed, cooled, and purified through molecular sieve dryers to remove moisture, CO₂, acetylene, and hydrocarbons; a portion is routed through an expansion engine to generate refrigeration; and the liquefied air is separated by boiling point in distillation columns. Heat exchangers recover energy from the outgoing waste nitrogen and product oxygen streams before final delivery or cylinder filling, supported by automated control systems throughout.
Yes. Sanghi Overseas offers complete project support, including engineering, installation supervision, commissioning, operator training, and technical assistance to ensure the long-term performance of every Oxygen Gas Plant and Nitrogen Gas Plant.
Choosing the right plant depends on required gas purity, production capacity, daily consumption, industry application, available utilities, installation space, and future expansion requirements. Sanghi Overseas's engineering team works through this directly with each customer — starting with a market and feasibility study, then technology and capacity selection, infrastructure and site planning, and equipment supply through to commissioning and operator training — to deliver a plant sized correctly the first time.
Yes. Sanghi Overseas is an ISO 9001:2015-certified company, and its Oxygen and Nitrogen Gas Plants are engineered to meet international quality and safety requirements for industrial and export projects.
