Liquid Oxygen Plants

BDM Cryofusion & Mandressi Italia is a reputed and known company for manufacturing and exporting liquid oxygen plants, which are fabricated under the guidelines of 'Felice Mandressi' of Italy. We have acquired complete technology along with drawings and designs of liquid oxygen generating plant in order to meet all the international standards and specifications of European and American pharmacopeia for liquid oxygen. Apart from optimum performance, the products are acknowledged worldwide for working efficiency, low upkeep expenses and longevity.

Backed by well qualified engineers and international technology, our liquid oxygen production units of our company take raw materials from CE certified vendors in order to make the plants perform exceptionally in terms of reliability, longevity and functionality. In order to fabricate the plants in compliance with the international standard, our company forms an R&D department that analyzes the market and adds the newest technologies in our product range. Our liquid oxygen plants find application for a wide range of industries and are designed to perfection. Over the period of past 28 years, we have been serving a number of clients all over the world including Africa, Middle East and South East Asia.

Process Description

STEP I : Air is sucked by a multi stage air compressor and passed through the following stages.

STEP II : COMPRESSION OF AIR

This is performed by the multistage highly efficient air compressor.

STEP III : PURIFICATION OF AIR

This is performed by the Process Skid.

STEP IV : COOLING & LIQUIFICATION OF AIR

This is performed by a highly efficient expansion engine and also by a refrigeration unit (for 100% liquid output).

STEP V : AIR SEPARATION (RECTIFICATION)

This is performed by the special AIR SEPARATION UNIT consisting of upper column, lower column and special exchangers. The separation air is by the CRYOGENIC PROCESS. The final product from a liquid Oxygen/Nitrogen goes to the storage tank.

STEP VI : CRYOGENIC STORAGE TANKS

Cryogenic Vessels are developed for storage and carry liquid gases at sub-zero temperatures. Manufacturing of such cryogenic tanks requires special technical knowhow and sophisticated fabrication techniques. We have developed the necessary technology to manufacture cryogenic vessels.
