OMEGA AIR: NC-GEN - Compact nitrogen generators COMPACT NITROGEN GENERATORS NC-GEN provides an alternative for gas supply that is more cost effective than N2 gas cylinders. PSA Nitrogen Gas generator technology guarantees consistent high N2 purity in the range from 96% to 99.999% PSA can produce nitrogen at variuos range of purities. The lower the purity, the lower is the cost of nitrogen production. For example, the quality of vegetable oil can be maintained by blanketing with 99,5% nitrogen purity. Normal nitrogen purity for food processing is in the range from 99% to 99,5%. Lower purity nitrogen in the range from 96% to 99% is often used in fire and explosion prevention. High purity with nitrogen content from 99,9 % to 99,999 % is typically used for laser cutting, electronics soldering and pharmaceutical applications. Compact nitrogen generators are ideal for their compact size, safety, reliability, and ability to generate N2 gas wherever it is needed. NC-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. 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 Food processing: - Wine blanketing - Beer dispense - Oil sparging - Fruit storage Compact nitrogen generators Fire prevention Explosion prevention Chemical blanketing Laser cutting When the CMS is at high pressure, it selectively adsorbs oxygen, allowing nitrogen to pass through it at the desired purity level. While one vessel is at high pressure to produce nitrogen, the second vessel is depressurized to remove the adsorbed oxygen, which is then vented to the atmosphere. The automatic switching between adsorption and desorption between the two beds enables the continuous production of nitrogen. By adjusting the size of the air compressor and adsorption vessels containing the CMS, a large range of flow and purity combinations can be met. PSAs can economically produce nitrogen gas at flow rates from less than one cubic meter per hour to greater than a few thousand cubic meter per hour at purities ranging from 96% to 99.999%. Industrial nitrogen gas can be produced by either separation of gaseous air using adsorption (PSA) or fractional distillation of liquefied air using cryogenic methods. Electronic soldering 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 carbon molecular sieves (CMS). The remaining impurities such as carbon dioxide and residual moisture are adsorbed by the CMS at the entrance of the adsorbent bed. Injection moulding Nitrogen is an inert gas that is suitable for a wide range of applications, covering various aspects of chemical manufacturing, processing, handling, and shipping. Nitrogen has low reactivity and it is excellent for blanketing and is often used as purging gas. It can be used to remove contaminants from process streams through methods such as stripping and sparging. Due to its properties it can be used for protection of valuable products against harmful contaminants. It also enables safe storage, usage of flammable compounds and can help prevent combustible dust explosions. Pressure testing Pressure swing adsorption PROD. YEAR: PROD.

Molecular sieve 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. NC-GEN generators ensure constant nitrogen production with reduced range of optional equipment for competitive price. Carbon molecular sieve 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 NC-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: NC-GEN - Compact nitrogen generators Components 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 oxygen is adsorbed. 2. Nitrogen 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...
