Atlas Copco’s introduction of its all-new range of OGP+ generators takes all the advantages of on-site oxygen generation to a completely new level. In a compact, complete design concept, inspired by customer needs, OGP+ offers best in class in performance, productivity, reliability, ease of use, cost saving, and self-regulation. 

By optimising PSA technology, the OGP+ sets new efficiency standards. At full load, it consumes 30% less feed air to produce the same amount of oxygen as a traditional generator. As a result, operators enjoy double-digit reductions in the total cost per unit of oxygen

Atlas Copco oxygen generators use pressure swing adsorption (PSA) technology. In the OGP+ generator, continuous, automated feed air monitoring protects the integrity of the zeolite molecular sieve (ZMS) material that separates the oxygen from the incoming air. In addition, the OGP+ monitors every unit of oxygen it produces. If any purity issues arise, the generator intervenes and (if pre-set to do so by the user) stops the oxygen from reaching the application until the purity level is restored.

The OGP+ unit produces oxygen of up to 95% purity, offering a more cost-efficient solution for high purity applications than delivered supplies. The exact purity level can be set at the push of a button. High purity production demands more energy, so for industrial applications that do not need 95% purity, the OGP+ delivers immediate operational cost savings.

The OGP+ introduces additional energy savings at low load with its in-house developed Variable Cycle Saver (VCS) technology. VCS optimises the PSA cycle to reduce the air requirement to what is needed to generate a lower volume of oxygen. By eliminating energy waste during lower demand, VCS generates up to 70% extra energy savings

The OGP+ also saves production floor space. Thanks to its optimal utilisation of the ZMS, and the in-house designed aluminum adsorbers, the generator occupies a very compact footprint.

Advanced features and benefits

The OGP+ is available in 8 models with a flow capacity ranging from 2-37 Nm³/h.

Each machine is complete with an O2 sensor, digital flow meter, and pressure regulator included as standard. Advanced features include a controller with a large HD colour touchscreen that offers easy gas purity selection, purity alerts, and connectivity options. In addition to feed air and oxygen purity monitoring and interception, automatic start-up allows for plug-and-play installation. At the same time, the zirconia oxygen sensor’s long lifetime contributes to reduced service intervention needs and costs.

Compared to delivered oxygen supplies or other on-site generators, the OGP+ really raises the bar for all key benchmarks, from efficiency to performance and reliability,” said Ben John, Business Line Manager at Industrial Air, Atlas Copco UK “Customers enjoy a stable oxygen supply and purity at a significantly lower cost per unit of oxygen”.
