OMEGA AIR: OC-GEN - Compact oxygen generators COMPACT OXYGEN GENERATORS OC-GEN provides an alternative for gas supply that is more cost effective than O2 gas cylinders. PSA Oxygen Gas generator technology guarantees consistent O2 purity in the range from 90% to 95%. Oxygen behaves differently to air, compressed air, nitrogen and other inert gases. Even a small increase in the oxygen level in the air – to just 24 % can create a dangerous situation. It becomes easier to start fire, which will burn hotter and more fiercely than in air. Oxygen is also very reactive. Pure oxygen can react violently with common materials such as oil and grease. Materials such as textiles and rubber will burn vigorously in oxygen. WHY GENERATE YOUR OWN GAS RATHER THAN USING CONTRACT SUPPLY? • Safety reason • Simple and Ready on demand • Total control over production • Production capacity fit your needs • No icing of the liquid gas tanks • No losses of the gas due to evaporation • Lower costs • No contractual limitations Pressure swing adsorption Oxygen, is present in the air with concentration around 21%. Oxygen is at atmospheric conditions always present in gas phase with no odour, colour or taste. It is a highly reactive substance, reacting with almost all elements, except inert gases. This is why it is used in a variety of applications: aquaculture, feed gas for ozone generators, glass blowing, leaching, NOx reduction for fuel burners, oxygen lancing, welding and health care. The first step in the PSA process is compressed air passing through a combination of filters and an activated carbon tower with the purpose of removing dust, entrained oil and water. The purified air is then directed to one of two adsorption vessels that are packed with molecular sieves (MS). The remaining impurities such as carbon dioxide and residual moisture are adsorbed by the MS at the entrance of the adsorbent bed. When the MS is at high pressure, it selectively adsorbs nitrogen, allowing oxygen to pass through it at the desired purity level. While one vessel is at high pressure to produce oxygen, the second vessel is depressurized to remove the adsorbed nitrogen, which is then vented to the atmosphere. Generating OXYGEN gas Oxygen gas can be produced by either separation of gaseous air using adsorption (PSA) or fractional distillation of liquefied air using cryogenic methods. PSA can produce oxygen at various ranges of purities. Typically purity of the oxygen produced by PSA is from 90% to 95% of the oxygen. The lower the purity, the lower is the cost of oxygen production. Field of use Metal production, welding, cutting Glass production Fish farms The automatic switching between adsorption and desorption between the two beds enables the continuous production of oxygen. By adjusting the size of the air compressor and adsorption vessels containing the MS, a large range of flow and purity combinations can be met. PSAs can economically produce oxygen gas at flow rates from less than one cubic meter per hour to greater than a few hundred cubic meter per hour at purities ranging from 90% to 95%. Healthcare, veterinary medicine Compact oxygen generators are ideal for their compact size, safety, reliability, and ability to generate O2 gas wherever it is needed. OC-GEN generators use minimal space and run quiet. They are also safe, reliable, and will generate nitrogen from the air requiring only an annual filter change for regular maintenance.

Zeolite is also protected from unexpected liquid intake. Robust ADC 4.0 assures reliable and stable operation and offers variety of settings. The controller is equipped with LCD display which provides all the necessary information about the operation. Compact generators with nitrogen production capacity, suitable for smaller consumers. OC-GEN generators ensure constant nitrogen production with reduced range of optional equipment for competitive price. Zeolite material is fixed in the column to prevent fast aging and inconveniently dusting. Adsorbent is also protected from unexpected liquid intake. High efficiency inlet and outlet filters Standard version of OC-GEN generators are equipped with high efficiency filters. Super fine coalescing filters at the inlet prevents contamination of the adsorbent material while a dust filter at the outlet intercepts the dust generated by the process.

OMEGA AIR: OC-GEN - Compact oxygen generators How generator works? Generator contains two vessels with adsorbing sieve material: 1. As the high pressure air enters the first vessel, it moves through the sieve, and the nitrogen is adsorbed. 2. Oxygen is then channeled to a buffer tank. 3. Directly before the first vessel is completely saturated, the feed air is redirected to move through to the second vessel, where the same process occurs. 4. Once that process is complete, the first nitrogen generator vessel is vented out to the atmosphere, allowing the waste gas to release from the sieve. 5....
