Is your business still getting its oxygen supply delivered in tanks?
Time to change directions! Bottled oxygen delivery has its drawbacks, including unreliable deliveries, oxygen wastage, and safety risks. Reconsider this outdated method and learn more about the benefits of on-site oxygen generation.

The industrial uses of Oxygen Generators
Air is about 78 percent nitrogen and 21 percent oxygen, with other molecules including carbon dioxide, argon and water. The oxygen from Air is very useful because of its high reactivity and is extracted for various industrial uses. It’s the second largest gas, by volume, used in industrial processes worldwide.
Around 55% of artificially produced oxygen is used in the manufacturing of steel where enriching the air with oxygen increases reaction rates. Oxygen is used in metal refining, fabrication, chemical and petroleum processing, pharmaceutical manufacture, glass and ceramic manufacture, paper manufacture, medicine and healthcare. Oxygen is also combined with other gases and used in gas welding, gas cutting, flame cleaning, flame hardening and flame straightening. And the source of all this oxygen is either Oxygen tanks or an on-site Oxygen Generator.
How Oxygen Generators work?
Great question! Oxygen Generators & Oxygen Concentrators use a similar working principle - PSA (Pressure Swing Adsorption) method to produce oxygen.
How it works: oxygen molecules are separated from other molecules within a clean, dry compressed air stream by trapping nitrogen using adsorption which is a simple, reliable and cost-effective technology that enables continuous, high-capacity oxygen flow at the desired level of purity (90% to 95%).
Adsorption happens when atoms, ions, or molecules from a substance (compressed air in this case) adhere to a surface of an adsorbent. PSA technology isolates oxygen molecules from other molecules (nitrogen, CO2, water vapor and trace gases) to leave high-purity oxygen at the outlet of the generator. The process takes place in two separate pressure vessels (Tower A and Tower B), each of which are filled with a carbon molecular sieve, that switch between a separation process and a regeneration process.
Renting oxygen tanks versus on-site Oxygen Generator?
Let’s compare having an on-site Oxygen Generator with the common practice of renting tanks from an oxygen tank supplier. Here’s what you need to consider:
- You’re paying rent for a minimum of three oxygen tanks all times. One is being used, the second is a replacement and the third is the empty tank waiting to be collected.
- Oxygen tanks take up a large amount of valuable floor space as they sit in their racks. And they need to be kept in an area that won’t create a health hazard.
- They are also very heavy to maneuver and require special equipment and time to handle correctly.
- Contamination inside the oxygen tank can occur over time when the pressure drops below 34 bar . This creates an estimated 14% wastage of gas when you rent from a oxygen tank supplier.
- Switching tanks also reduce the production overall up-time, which can add up over the course of a year
- Inconsistent purity levels occur when dealing with rented cylinders.
Why you should buy on-site Oxygen Generators?
Most of our customers started off by renting from oxygen tank suppliers. When they started looking into purchasing an oxygen generator it was usually because they had increased capacity needs and the amount of tank they needed to rent became difficult to manage. For some of them their high oxygen gas requirements meant that their tanks could be consumed in a matter of days. Switching tanks also reduced their overall up-time, which can add up over the course of a year. Then there’s the issue of contaminants and inconsistent purity levels that they discovered when dealing with rented cylinders. They chose to invest in on-site Oxygen Generators because they wanted greater control over purity, cost-efficiency, and a continuous uninterrupted supply of oxygen for their work.
