Air Separation Machine

Supported by a well equipped R&D unit and internationally approved Italian technology, BDM Cryofusion & Mandressi Italia has become able to fabricate Air Separation Plants in accordance with the ISO parameters and CE standards. The machines generate both oxygen as well as nitrogen with purity upto 99.97% and 99.99% respectively. The capacity of the systems is ranging from 50 m3/hr up to 5000 m3/hr. Our company designs and manufactures the air separation plants that produce oxygen and nitrogen from air through the process of compression, cooling, liquefaction and distillation of air.

Our company in collaboration with Cryofusion & Mandressi Italia manufactures the machines that are unparalleled in the industry in terms of reliability, functionality and maintenance. Before being shipped, a machine has to pass through our multi layer quality testing procedures. After passing all the procedures, it is put for packaging and shipping. With the systems, we send well trained and skilled engineer to commission, erection and install it. After running the plant successfully and providing training to the operators, the engineer would leave the site.

liquid oxygen plant Benefits of our air separation plants

  • Low Working Pressure
  • Low Operating Cost
  • Sturdy Design
  • Low Maintenance Cost
  • Trouble Free Operation

We systems come up with the latest technology so that stand out among our competitors in the industry. The life span of our plants is minimum 35 years; however they are smoothly performing for more than that. Professionally designed and manufactured, the products are available in different capacities and operate at a working pressure of 6 to 8 bar. There is an R&D team, which is responsible for analyzing the industry requirement and updates our products accordingly. We are not only an ISO certified company, but also have got CE approval for quality.

Scope of Supply

Air Compressor

The air compressor is a multi stage, heavy duty water-cooled air compressor for round the clock operation, which horizontal type complete with fly wheel inter cooler, foundation bolts, motor pulley, motor, v belt, guard and slide rails. This is employed to compress atmospheric air.

Air purifier/process skid

Since the compressed air carries impurities like CO2 and moisture, they should be alleviated as quickly as possible. To alleviate the impurities, the air purifier is employed.

Expansion Engine

Complete with branded motor/starter of Siemens/ABB world class quality. Expansion Engine is complete with hydraulic valve control, bursting disc for safety, complete with fly wheel pressure gauge, motor pulley V belt, Belt guard, slide rails inter connected pipes (inlet and outlet)

Air Separation Column - Cold Box

This comprises of the complete cold box (outer steel casing) complete with top column, bottom column, condenser, sub-cooler, re-boiler, exchanger 1, exchanger 2, control panel, instruments, pressure gauges, digital automatic temperature scanner withpt-100 sensors, expansion valves, analysis valves, inlet & outlet, air oxygen and nitrogen, gas lines with control valves neatly mounted and firmly fixed on the cold box.

Liquid Oxygen Pump

Horizontal single acting pump with Piston, Piston Rings - oil free - Teflon with guide ring, Safety Devices, Non-Return Valves, Motor with Pulley, V-Belts, Belt Guard, Inter Connecting Pipes with ducting to cold box suitable for filling Oxygen.

High Pressure Filling Manifold

It is employed for filling high-pressure Oxygen to Cylinders. It holds a main High Pressure Isolation Valve and a Pigtail filling connection with individual regulation Valve with Pressure Gauge and Safety Relief Valve.

Water Pump

The pump is offered with the plant to be coupled with the air compressor and the cooling tower.


Oxygen Purity Apparatus will be provided along with to measure the purity of Oxygen.
