BDM Cryofusion & Mandressi ITALIA is one of the Leading Manufacturers of Air Separation Plants with Société Générale de Surveillance (SGS) quality approval and ISO 9001:2000 certification.

High Purity Gas Generators


Process Description

STEP I: Atmospheric Air enters into the first tower and passes through the adsorbent layer.
STEP II: The other Tower is in the process of regeneration of Oxygen
STEP III: Nitrogen and the vapors are adsorbed by molecular sieve letting the oxygen to pass by.
STEP IV: Oxygen flows through the tower and gathers at the top of it. Ultimately the Oxygen gas releases as the output.

Salient Features:

Full Automation
All systems are designed for un-attended operation and automatic Oxygen demand adjustment. Lower Space Requirement and Short installation period The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory. Installation is very easy and convenient

High Reliability
Very reliable for continuous and steady operation with constant Oxygen purity. Plant availability time is better than 99% always.

Fast Start up
Start-up time is about 30 minutes to get desired Oxygen purity. So these units can be switched ON & OFF as per Oxygen demand changes.

Molecular Sieves Life
Expected Molecular sieves life is more than 10-years i.e. whole life time of Oxygen plant. So no replacement costs.

Applications:

  • Water Process
  • Ferrous Metallurgy
  • Non-ferrous Metal Refinery
  • Coal mines
  • Pharmacy
  • Others: Chemical industry production, solid garbage burning, concrete production, glass manufacturing, medical oxygen, etc.
