Industrial VPSA

Airox Technologies Limited has proved market leadership in PSA/VPSA by installing and running successfully more than 100 PSA oxygen generators in India. Airox in collaboration with AirSep Corporation, USA which the world leader in Vacuum Pressure Swing Adsorption (VPSA) & Pressure Swing Adsorption (PSA) technology which has 25 years of experience in the design and manufacture of onsite PSA/VPSAOxygen Generation Systems. Each system is custom engineered for the end-user's specific site and process requirements.

AirSep Corporation offers custom-engineered Vacuum Pressure Swing Adsorption (VPSA) Oxygen Systems designed to the specific requirements of installation, with capacities ranging from 3,000 SCFH (79 Nm3/hr) to 115,000 SCFH (3,023 Nm3/hr).

All AirSep PSA/VPSA oxygen systems are optimized for peak efficiency, low power consumption, high reliability with an expected on-stream efficiency of 99%, and an expected equipment life of +20 years. All system designs are highly integrated into skids to minimize footprint size, and simplify on-site installation.

AirSep VPSA Oxygen Systems are currently in use all over the world in remote, harsh, and/or demanding environments.

AirSep VPSA Oxygen Systems standard features include:

  • Remote monitoring of system operation by AirSep engineers
  • Critical process parameters monitored and recorded every 250 milliseconds
  • Automatic turndown capability from 100% to 0% flow capacity
  • Designed in accordance with local standards
  • Automatic and unattended operation
  • On-site start-up assistance by AirSep technicians anywhere in the world
AirSep VPSA Oxygen Generator Benefits
  • The only utilities required are Cooling water & Electrical power. So cost of electricity consumed is the cost of Oxygen production. As compared to cryogenic plants, PSA and VPSA units help you recover your investment costs much faster due to low cost of Oxygen production. VPSAplant saves 65-70% cost on oxygen consumption compare to tradition cryogenic oxygen.
  • PSA and VPSA technology has been used in AirSep Oxygen plants for over three decades and our generators are operating successfully all over the world. This technology is time tested and very well proven. We use in-house molecular sieves which ensures that you get many years of trouble free operation and long life from your investment.
  • AirSep Oxygen Gas Plants are designed to be turned ON and OFF on-demand with the push of a single button. Oxygen Gas Generators only require 5 minutes to start producing high purity Oxygen and there isn't a need for the unit to be running when you are not consuming Oxygen gas. This is unlike the cryogenic systems where the unit has to be kept running to maintain Oxygen purity, whether gas is needed or not.
  • AirSep incorporates the use of several skids and designing the system in a modular construction. This feature allows easy transportation and easy installation of the system at your site. Our engineer is present at site to oversee installation and also to assist with commissioning and training of your personnel.
  • There are very limited moving parts in the PSA and VPSA process and hence with routine preventive maintenance, AirSep Oxygen Generators gives 20 + Years of trouble free operation.
  • When you install an AirSep Oxygen Gas Generator on-site, you are in control of your Oxygen supply. If you are currently using cylinders, then there is always dependence on your suppliers and there is no guarantee of the purity of Oxygen being supplied. With AirSep system, you can be sure of the purity of Oxygen with the included Oxygen purity analyzer.
  • AirSep does not compromise on the quality of molecular sieves and has own resources to procures it Unlike the Chinese make molecular sieves that are available for much lower cost, there are no problems in our molecular sieves such as excessive dust and low Oxygen purity

Award wining AirSep VPSA Installation

The Rocky Mount AirSep VPSA Oxygen Generation System has been Selected to Receive an Award at the ACEC/NC Engineering Excellence Awards.

RALEIGH, N.C. – The Wooten Company, one of the most reputable engineering, planning and architectural firms in North Carolina, has received notification from the North Carolina Chapter of the American Council of Engineering Companies (ACEC/NC) that the firm has received the 2013 Engineering Excellence Award for demonstrating the highest degree of achievement, value and ingenuity in design of the Rocky Mount Oxygen Generation System.

This award was presented to The Wooten Company because of their ability to collaborate with the City of Rocky Mount, state agencies, sub consultants and equipment vendors in addressing the replacement of the obsolete and highly energy inefficient cryogenic oxygen generation plant, performing a critical function in the City’s Water Reclamation Facility, with an alternative system customized to needs of Rocky Mount.

Management at a 21 MGD wastewater treatment plant (WWTP) in Rocky Mount, NC reports saving over 65% of electric power costs for oxygen production by replacing a cryogenic plant with a customengineered vacuum pressure swing absorption (VPSA) system. The move was spurred by reduced input and increased power costs for the WWTP’s pure oxygen, biological nutrient removal (BNR)-type activated sludge system.

“The new VPSAsystem is costing us only $345/day for electricity, compared to over $1000/day with the cryo plant,” said Kirk Bass, superintendent of wastewater treatment.
