Oxygen Generating System: Layout, Features & Benefits

On-Site-Gas-Blog-ImageFor almost 30 years, On Site Gas Systems has been providing industries with standard oxygen generating systems, as well as custom designed oxygen generators. We serve more than 70 countries and provide systems for dozens of industries. Our systems are reliable, which is why they are frequently utilized in mission-critical. The oxygen generators we offer our clients can be used virtually anywhere.

Standard Oxygen Generators

Every one of our systems is capable of lasting for decades, in even the most remote locations and harshest climates around the world; furthermore, our oxygen generating systems can be used globally because they are compatible with worldwide power supplies.

Custom-Made O2 Generators

Once the design process is complete, we build your customized oxygen generator to meet your exact needs. . Upon completion, you receive an unlimited supply of oxygen at your required flow, pressure and purity.

Pressure Swing Adsorption (PSA) in Oxygen Creation

The O2 generators that we create use Pressure Swing Adsorption as a means to generate oxygen. Adsorption refers to the process of physically separating gas molecules from one another.

Oxygen Generator System Layouts for 95 Percent and 99 Percent Purity

For 95 percent purity:
This oxygen system consists of a feed air compressor leading to a dryer, which leads to air storage, then to the two sieve beds and lastly, to an oxygen surge tank.
For 99 percent purity:
As with the 95 percent purity level system, there is a feed air compressor leading to a dryer, to air storage, to the two sieve beds and an oxygen surge tank; however, following the O2 surge tank is a 99 percent oxygen generator which leads to a 99 percent oxygen surge tank, then to a buffer tank and lastly, to a booster compressor.

Generating Oxygen Using the Pressure Swing Adsorption Process

Compressed air is used to pressurize a vessel that is filled with zeolite. The zeolite separates the molecules from one another. When the air is forced into the zeolite filled vessel, the oxygen molecules become trapped; however, the other molecules can float freely. As pressure is released, the trapped oxygen molecules are collected in the O2 surge tank for use; meanwhile, the unwanted gases are released back into the air via a pressure release valve. Once released, these molecules recombine with the ambient air. As the first sieve bed releases the nitrogen molecules, the second bed begins the process again. This ensures that you never run out of oxygen.

Benefits of Generating Your Own Oxygen

Prior to on-site oxygen generating systems, businesses, industries and hospitals had no choice but to purchase their oxygen elsewhere and have it delivered; however, all of the hassle associated with purchasing oxygen in bulk can be eliminated with an on-site oxygen generator. Our oxygen generators are a cost-effective choice: The average cost per CCF of self-generated oxygen is one-third to one-half less than the costs associated with purchasing cryogenic oxygen. With On Site Gas Systems, there are no delivery fees and our systems usually pay for themselves within an 18-month time frame.

Besides being economical, the oxygen generator systems from On Site Gas Systems offer:

  • Dependability – an On Site Gas Systems’ oxygen generating system uses the air that surrounds it to create the oxygen; therefore, our clients never have to worry about running out of oxygen.
  • Improved Safety – through a low operating pressure and the elimination of hazardous storage.
  • Simplicity – we make it easy for our clients with no contracts to sign. Our clients can buy, rent or lease an oxygen generating system. An easy to use touch screen control allows for purity level assurances, diagnostics, operation diagrams and maintenance schedules.
  • Flexibility – many of our On Site Gas Systems site systems can be transported. This portability allows these systems to function anywhere that air and electricity are available.
  • Fully Automatic – production begins as soon as a downstream is sensed.
  • Lease/Rental Options – instead of purchasing your system outright, you can write it off as an operating expense.

Whether our client needs a standard O2 generator, portable oxygen generators or a custom-designed oxygen generator, we are dedicated to providing our clients with the most reliable, innovative and cost-effective products available in today’s market. Our on-site oxygen generators are not only convenient; they eliminate any concerns you have related to running out of oxygen. To learn more about our systems, contact us today.

10 Features & Benefits of Nitrogen Cylinder Filling Stations


Features and Benefits of a Self-Generating Nitrogen Cylinder Filling Station

Before the ability to generate nitrogen on-site became available, companies had to purchase their nitrogen elsewhere, schedule a delivery and worry about running out of nitrogen before the delivery arrives. Today, we have the ability to generate nitrogen on-site. These on-site nitrogen generation systems have changed the way that many companies attain their nitrogen.

On-site Nitrogen Generator Systems Eliminate the Need for Bulk Deliveries

The nitrogen generators and nitrogen filling stations On Site Gas Systems offers eliminate the need for bulk purchases of nitrogen. In addition, all of our systems usually provide a return on investment within 18 months’ time. The nitrogen generator systems we offer are designed to last for decades.
Our nitrogen filling stations are used all over the world. As long as you have air and electricity, our nitrogen generator systems can operate; furthermore, the N2 generator systems we offer are compatible with worldwide power supplies.

On-site N2 Generation

Membrane Technology for Nitrogen Generation
The membranes used in our nitrogen membrane generators are bundles of hollow fibers. These fibers are porous and designed to allow oxygen molecules to pass through; however, the nitrogen molecules are too large and unable to exit. Air is forced down the fiber, which pushes the smaller oxygen molecules out of the pores, meanwhile the nitrogen molecules are captured at the opposite end.
The air that is being pushed through the membrane is usually heated: This heated air excites the oxygen molecules; thus, increasing the likelihood that they will permeate the holes in the membrane.
If you add a nitrogen filling station – your Nitrogen Generaror your staff will be able to fill their own nitrogen cylinders.

10 Features & Benefits of Nitrogen Cylinder Filling Stations

Nitrogen fill stations are safe, inexpensive and easy to maintain, which is why any company that purchases bottled nitrogen can benefit from an onsite nitrogen filling station.

  1. With a nitrogen fill station, cylinders can be refilled quickly and easily.
  2. An onsite N2 filling station means you never have to worry about running out of nitrogen again.
  3. Waiting on a nitrogen delivery is a thing of the past.
  4. As long as you can access electricity and have air, you can produce nitrogen with a nitrogen generator wherever you need it.
  5. You produce nitrogen when you need it.
  6. There are no delivery or transportation charges when you use a nitrogen fill station.
  7. An N2 filling station takes up very little space and can last for decades.
  8. Safety is improved because there is no need to store or use huge containers of nitrogen.
  9. A nitrogen fill station eliminates the need for gas contracts.
  10. A nitrogen filling station is a cost effective solution: It can reduce the costs related to nitrogen substantially.

At On Site Gas Systems, we concentrate on providing our clients with the most dependable, innovative and versatile nitrogen generating systems and N2 filling stations available. If you are interested in learning more about the quality products we offer, contact us today.
