This is the delivery of one 99.5% purity, 1700 Nm3/hr nitrogen generator for a pharmacy company, totally three sets same specification nitrogen generators are ordered.

In later September 2019, Gamma Gas launched a new energy-saving PSA nitrogen generator, the NGS-12V nitrogen generators. This nitrogen generator achieves the best energy-saving performances thanks for Gamma Gas technology breakthrough of 12V process and the optimized adsorption tower structure and the using of most advanced carbon molecular sieve. It is the outcome of Gamma Gas 5 years constant R&D efforts. For nitrogen generator from many manufacturers, producing 99.99% purity, 100 Nm3/hr nitrogen requires an GA55 Atlas Copco air compressor, while Gamma Gas NGS-12V nitrogen generator only requires GA37+ air compressor, and the flow rate can reach 120 Nm3/hr. Producing 99.999% purity, 100 Nm3/hr nitrogen, many factories requires an GA90 Atlas Copco air compressor, while Gamma Gas NGS-12V nitrogen generator only requires a GA55+ air compressor, and the production can be 110 Nm3/hr. This is a big breakthrough in PSA nitrogen generator energy saving field, it remarkably reduces the electricity consumption, saving operation cost every hour. After the launch of NGS-12V nitrogen generator, customers are astonished by its performance. [From the machines working at our workshop, we know Gamma Gas nitrogen generators have good operational reliability, but really did not realize that your this new machine consumes so little compressed air. This nitrogen generator must be installed in our workshop, this energy-saving machine is what we are looking for for a long time", this is the comment from our c

For some customers, they need mobile containerized outdoor use onsite nitrogen generator to be used outdoor, suitable to be used under wide temperature range.

These two sets of 99.9% purity, 1200 Nm3/hr onsite gaseous nitrogen generators are supplied for a Calcium carbide field customer. Wonderful weather, very suitable for site installation. Actually there is little site installation work except lifting them to the right positions.

For some customers, their oxygen consumption location is in dangerous area, which need explosion proof oxygen generator. This oxygen generator is certified as explosion proof product, suitable to be used in such area.

These are three 99.99% purity, 80 Nm3/hr flow rate cabinet nitrogen generators running at site, installed one week ago.

This nitrogen generator is supplied to one big engineering company, they have one power plant project in Georgia, the nitrogen generator is used to provide clean and dry protective gas during plant starting stop procedure. The pressure vessel of this nitrogen generator complies with ASME standard, U stamped by International Certification Body. The adsorption towers are fatigue pressure vessel, with number of cycles 500,000 times/year, and the design life is 20 years.

PSA Nitrogen Generator's Technical Principle PSA nitrogen generator is a machine producing nitrogen by separating nitrogen from air. It adopts the principle of PSA(pressure swing adsorption). Pressure swing adsorption processes rely on the fact that under pressure, gases tend to be attracted to solid surfaces, or "adsorbed". The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or desorbed. PSA processes can be used to separate gases in a mixture because different gases tend to be attracted to different solid surfaces. When air is passed under pressure through a vessel containing an adsorbent(carbon molecular sieve) bed that attracts oxygen more strongly than it attracts nitrogen, part or all of the oxygen will stay in the bed, and the gas coming out of the vessel will be enriched in nitrogen. When the bed reaches the end of its capacity to adsorb oxygen, it can be regenerated by reducing the pressure, thereby releasing the

Why choose Gamma, not other suppliers? High reliability For PSA oxygen generators, the most important factor is equipment operation reliability, especially for overseas market, where maintenance and repair service should be minimum. Keeping the equipment run at the designed purity and flow rate without malfunction is of critical importance. Similar to other suppliers, Gamma Gas manufactures PSA nitrogen/oxygen generators, but unlike other suppliers, Gamma is using the most advantage process and special equipment structure to ensure long time operation stability. Now in China, there are many companies manufacturing PSA N2/O2 generators, but how many of their products are running without purity decrease? without flow rate drop? without problems such as molecular sieve ejection,etc. Gamma Gas strongly recommend customers to contact us for more details. Energy-saving As PSA N2/O2 generator itself consumes very little power, the main power consumption is the air compressor. Compared with other suppliers, for same flow rate and purity, with Gamma's special process and structure, the compressed air needed is about 20% less, theref

Nitrogen use in the lab Nitrogen gas has been used in laboratory analysis for decades. In the past, labs were required to have their nitrogen gas supply delivered in cylinders or in bottles from their closest nitrogen plant, which for some labs could be some distance away. These cylinders or bottles would then supply a chromatography instrument, or perhaps a detector in the case of GC, allowing the lab to carry out its analysis. However, for most mass spectrometers, a high volume of nitrogen gas is required meaning cylinders or bottles would be consumed in a matter of days, primarily when using LC-MS. This can lead to the regular interruption of analysis and inconvenience of switching over cylinders for analysis to continue. Furthermore, cylinders and bottles deliver inconsistent purity when they reach the lower end of their capacity as contaminants can enter the empty space in the cylinder and mix with the nitrogen. These impurities can have an impact on the integrity of analysis as they can react with the sample. There is an alternative for nitrogen cylinders, an on-site nitrogen generator. A nitrogen gas generator not only removes the hassle of having to change over cylinders, it provides an uninterrupted supply of gas at a consistent purity. This consistency is generated using one of two technologies, namely, Pressure Swing Adsorption (PSA) and membrane nitrogen generators.

Gamma nitrogen generator advantages 1 Best CMS, GN-UC from Iwatani/Kuraray In today`s world, the best CMS comes from IWATANI, Japan. Better than Takeda, BF,ete, let along Chinese CMS. In China, many manufacturers use Takeda, BF,etc CMS, even Chinese CMS, pretending to be IWATANI CMS. If they use real IWATANI CMS, they can just use the 1.5GN series, not its best model CMS, the GN-UC. To prevent many Chinese manufacturers` cheat, IWATANI authorizes only three Chinese manufacturers to get its best GN-UC CMS. Gamma is one of the three manufacturers.
