Atlas Copco on-site oxygen generation means 30% increase in efficiency plus 70% extra energy savings
Atlas Copco says the introduction of its 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+ is claimed to offer best in class in performance, productivity, reliability, ease of use, cost saving, and self-regulation.
The company says that, by optimising pressure swing adsorption (PSA) technology, the OGP+ sets new efficiency standards. At full load, it is claimed to consume 30% less feed air to produce the same amount of oxygen as a traditional generator. As a result, operators will enjoy double-digit reductions in the total cost per unit of oxygen, says the company.
Atlas Copco oxygen generators use 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 aluminium adsorbers, the generator occupies a very compact footprint.
