Liquid oxygen plants

We are famous for manufacturing high quality liquid oxygen plants in technical collaboration with Felice Mandressi Italia. Mandressi is known all over the world for its latest cutting-edge technology and world-class designing. Our plants are fabricated in compliance with international standards using the components that are sourced only from the approved vendors. From time to time, our engineers are sent to the Italian company for getting the nuances of the latest technologies and designing. Our engineers with their mastery of the latest Italian technology and designing fabricate liquid oxygen machines that are at par with best. Our plants are unmatched in terms of performance, innovation and pricing. We use the designs of the famous Italian company in the manufacturing of plants and machinery at our factory in New Delhi. We have made our name by delivering machines that are reliable, durable and high quality. Our premium quality liquid oxygen plants come in all sizes ranging from 50 Liter/hour to 20,000 Liter/hour. Our plants guarantee generation of oxygen with purity up to 99.7%, which is considered ideal for medical and other medical applications.

Manufacturing industrial gas plants in compliance with international quality standards, we have become a well-known name in the engineering sector. Having been certified by a number of acclaimed quality assurance companies such as Societe Generale de Surveillance (SGS), ISO 9001:2008 and CE, we are reputed for manufacturing and supplying the best plants and equipment. Since our establishment, we have sold over 360 plants to our clients in over 40 countries including Saudi Arabia, Qatar, Kuwait, Iraq, Iran, Afghanistan, South Africa, Yemen, Sudan, Peru, etc. Our clients are happy with the performance of the plants as well as after sales service.

Liquid Oxygen Plant
Basic principle

Our oxygen plants taps oxygen and nitrogen from the atmosphere air. Feed air is entered into the molecular sieve purification system to separate the moisture and CO2 from the process air. Afterward, it is liquefied by cryogenic cooling using the latest plate and fin, high efficiency heat exchangers and expanders. Liquid air is separated into oxygen and inert gases in the air separation column. Liquid oxygen is stored in a liquid storage tank.

Oxygen Plant
Scope and Supply :
Air compressor
Air is compressed at a low pressure of 5-7 bar using the latest compressor (screw/centrifugal type).
Pre Cooling System
In the second stage, a refrigerant is used for pre-cooling the process air to temperature around 12 degrees Celsius before it enters the purifier.
Purification of Air by Purifier
The air enters a purifier, which is made up of twin molecular Sieve driers that function alternatively. The Molecular Sieve separates the carbon dioxide & moisture from the process air before the air reaches at air separation Unit.
Cryogenic Cooling of Air by Expander
The air must be cooled to sub zero temperatures for liquefaction. The cryogenic refrigeration and cooling is provided by a highly efficient turbo expander, which cools the air to temperature below -165 to-170 deg C.
Separation If Liquid Air into Oxygen and Nitrogen by Air Separation Column
Air that goes inside the low pressure plate fin type heat exchanger is cleaned of moisture, oil and carbon dioxide. It is cooled inside the heat exchanger below sub zero temperatures by air expansion process in the expander. It is expected that we achieve a difference delta as low as 2 degree Celsius at the warm end of exchangers. Air gets liquefied when it reaches at the air separation column and is separated into oxygen and nitrogen by the process of rectification.
Liquid oxygen is stored in a liquid storage tank
Liquid oxygen from the cryogenic storage tank is compressed to high pressure in a cryogenic liquid pump. Gaseous oxygen is obtained after vaporizing liquid oxygen in an ambient air evaporator. The high pressure gas is, then, directed into cylinders or customer’s pipelines.
