Air Separation Unit

BDM Cryofusion & Mandressi Italia is engage in manufacturing and supplying a wide range of technologically advanced air separation units. We supply standardized packaged air separation units with Argon, which find application in typical process industries and gas supply chain distribution requirements. The units incorporate the latest centrifugal air compressors and are designed and developed as per the Low pressure Cryofusion & Mandressi process leading to high yield and optimum performance. The device mainly designed to fulfill the pre-cleaning of agro seeds at modern processing plants.

Key features of our air separation units include:

  • Argon recovery with 5 PPM purity
  • Fully automatic operation
  • Energy efficient
  • Nitrogen output at high purity up to 3 PPM
  • CE certified product
  • Durable and reliable

(Leak proof Column)

Cryogenic type completed with support and connected pipes and internal connections.

Supplied as packed units comprising of:

Outer Steel Casing: Manufactured with frame for mounting exchangers and separation column, control, etc.

Main Heat Exchanger: In air circuit in alloy coiled type-multi pass with high heat transfer coefficient. Argon welded stainless steel casing and tubes expanded for leak proof.

Liquefier: In air circuit in alloy coiled type-multi pass with high heat transfer coefficient. Argon welded stainless steel casing and tubes expanded for leak proof.

Bottom Column: Made out of Argon welded stainless steel with flanged ends for easy maintenance/repair with distillation trays of high efficiency with working pressure of 5 kg/cm2. The trays are dies fitted into the outer casing, which is Argon, welded.

Top Column: Made out of Argon welded stainless steel with flanged ends for easy maintenance/repair with distillation trays of high efficiency with working pressure of 0.4 kg/cm2. Large interspaced between trays for entertainment. The trays are dies fitted into the outer casing, which is Argon, welded.

Sub-Cooler: For liquid Nitrogen and liquid Oxygen made of special alloy.

Liquid oxygen & nitrogen filter: In stainless steel alloy containing absorption material and fine mesh filter complete with connection for regeneration.

Instrumentation: Complete instrumentation for control of liquid levels/pressure and analysis valves. The digital electronic temperature is an indicator with scanner and accurate PT-100 sensor. The expansion valves are manual control with long stem type with pointer and index. For liquid level measurement accurate DP Guage Manometer, Panel Mounted is provided. Pressure gauges are German-Feibig.

Cold Pipe Lines: All alloy in interconnecting equipments inside cold box.

Insulation Materials: The perlite is of sufficient quantity to insulate the cold box completely.
