Atlas Copco has launched its latest range of OGP+ Oxygen Generators to offer efficient, reliable, and cost-effective production of oxygen (O2) on-site, requiring only a supply of dry compressed air. These environmentally friendly machines deliver significant savings through lower total cost per cubic meter of oxygen, optimised uptime due to continuous oxygen supply and the delivery of guaranteed gas purity.
The on-site production or generation of oxygen as opposed to purchasing this gas from a vendor presents many benefits. The company’s new OGP+ 3-30 PSA (Pressure Swing Adsorption) machines offer continuous reliable on-site oxygen generation at a significantly lower total cost per unit of oxygen, and the user is able to choose the correct oxygen purity level for the application.
Zandra van der Westhuizen, Business Line Manager at Atlas Copco Compressor Technique, says, “To switch from sourcing the gas from a vendor to producing oxygen on-site is easy. All that is required is a compressed air system plus a gas generator and the plug-and-play machine is ready to produce oxygen on-site.
“Our Atlas Copco OGP+ generators are 30% more efficient at full load compared to a traditional generator. Moreover, thanks to the machines’ innovative Variable Cycle Saver technology, the OGP+ generators offer up to 70% in additional energy savings when oxygen demand is low. This all adds up to a lower cost per cubic meter of oxygen, delivering unparalleled cost savings.
“Reliance on a third-party supplier is eliminated,” adds Van der Westhuizen. “The user is in complete control, generating the exact amount of oxygen when needed at the correct and guaranteed purity required for the particular application. If more oxygen is required, simply run the generator a little longer. Bottom line – users only pay for the gas they need and use.”
Van der Westhuizen points out that the purity of purchased oxygen is usually over-specified for most application requirements. “An on-site generator not only achieves this high purity more cost-efficiently, but it also offers additional savings. Because generating oxygen of the highest purity uses more energy, the ability of on-site generators to set the correct purity for a particular application will significantly reduce the user’s operational costs.”
There is also no need for a facility to store oxygen cylinders or to install a large liquid oxygen tank. The OGP+ generator has a very small footprint and requires only a small space in a production facility.
Producing oxygen on-site removes the hassles of long-term contracts, logistics and safety concerns that accompany the ordering and handling of third-party oxygen cylinders. There is no need to move pressurised cylinders around the plant thus avoiding the potential risk of employee injuries. And finally, the elimination of oxygen transport and delivery reduces the user’s carbon footprint.
