In recent years, on-site gas production enterprises mushroomed, suddenly thousands of "professional research and development, manufacturing on-site nitrogen production equipment" companies and even groups, Dongguan City Troy gas Equipment Co., Ltd. on the status of on-site nitrogen production enterprises to talk about personal views and understanding, so that everyone can share.

Let's start with the system and equipment composition of the on-site PSA nitrogen machine. Its system composition mainly includes compressed air supply (generally screw compressor), compressed air purification (freeze dryer, filter, storage tank), nitrogen machine (some areas also need to add purification: Hydrogenation, carbon-supported catalyst, copper oxide or manganese oxide adsorption to achieve higher Nitrogen purity requirements), it can be seen that the nitrogen machine (nitrogen manufacturing machine, nitrogen Generator, N2(Nitrogen Generator) pre-stage system components, is completely external.

Even many (it can be said that each) company has the core technology of the nitrogen machine, which is basically composed of two adsorption towers (some people say that the composite adsorption bed, loaded with alumina, molecular sieve, sieve plate: Drill holes in the steel plate with steel wire mesh, spring or coconut mat), a small control cabinet (programmable controller PLC, basic several electrical components), control valves, pipes, air and nitrogen buffer tanks (some manufacturers in order to save costs, omit one or both, respectively, by the corresponding air storage tank and nitrogen storage tank to replace). It is also not difficult to see that the nitrogen machine is basically purchased parts, and there is basically no need to "develop and manufacture" by itself. The so-called technical core, as long as the respected customer you have the heart to open each of the "technical core", product introduction, product appearance should be much the same.

It is based on this, the entire industry should be technology, capital thresholds are very low, it should be that most companies are set up a shell company (entrusted to the registered company to set up the company, and then withdraw the funds), there are several "technical personnel" (or engaged in salesman, or engaged in so-called technical work, In a word know a little about the working principle of the nitrogen machine), a few welders, a shabby factory, one or two welding machines, to here a so-called set of "research and development, manufacturing, sales and service" in one of the "scale" company was established, you can strut the market. It can be said responsibly that there are some large scale, the earliest manufacturing of China's nitrogen machine, the most advanced technology of the "industry leader, leader" of the "big company", but so operated ------ attached to a grand title of a manual workshop just. The so-called modern enterprise management, domestic and foreign famous experts, scholars and research institutes cooperation, enterprises and even famous universities have set up a central laboratory and R & D room, ISO9000 quality demonstration system, ISO1400 environmental demonstration, famous association members, high-tech, national 863 project...... Too many to mention, in short, all the halo in one, to bear the "social progress, the survival of the world" of the great responsibility, but a brand.

And the truth? Demonstration system commissioned demonstration agency company, throw a little money to get it done, spend a little money is "member", many associations are not in the promotion of membership? Famous experts and research institutes are nonsense, which does not know, this industry even a national standard is not, many times can only refer to the "enterprise table standard", which university research institute all the so-called "on-site PSA nitrogen production" research project! Dear Nitrogen machine (nitrogen manufacturing machine, nitrogen Generator, N2(Nitrogen Generator) user friends, there are many companies advertised themselves in the country and even around the world have set up branches, don't believe, rent a room, an telephone, this is the branch, and some even found a "distant relatives", If his personal number is published, it will be called "branch" or "office". In order to advertise the "Fenggong achievements" of the enterprise, its customers are "at home and abroad", Foxconn, Samsung, petrochina...... America, South Africa, Southeast Asia... Which enterprise is big, which is his customer, which is far from his customer, as if the world's civilization and economic development are created by his enterprise.

There is a strange phenomenon, nitrogen machine companies have not heard of which companies bankrupt, why? This may envy a lot of other industries, because as long as the configuration of the "original import" changed to "domestic import", you can ensure "reasonable profits", you know, in the price is the only competition "assassin", some companies configure "high-end", and in fact in accordance with the real configuration, may not even the cost of materials. As the saying goes, "Don't make money also want to make shout" is it! No one makes a losing deal. So good cost performance, I'm afraid this industry has long been his family "exclusive".

In view of the current situation of Nitrogen machine (nitrogen manufacturing machine, nitrogen generator, N2(Nitrogen Genertor) enterprises, Dongguan City Troy Gas Equipment Co., Ltd. adheres to the business philosophy of "pragmatic, honest, creative and enterprising", starting from the fundamental interests of customers and their own development needs, to adopt new flexible and diverse cooperation models. Here to share with you.

The on-site nitrogen system is divided into three parts: outsourced molding equipment, outsourced core materials, and nitrogen machine body design and manufacturing. They are introduced as follows:

Purchased equipment: Including air compressors, freeze dryers, filters and air, Nitrogen storage tanks, etc., these are generally in the industry, suppliers to nitrogen machine (nitrogen manufacturing machine, nitrogen Generator, N2(Nitrogen Generator) enterprise discount is low (matching price), Dongguan City Troy gas Equipment Co., LTD. We choose and negotiate for customers, and directly contract with the corresponding users, on the one hand to ensure that users can obtain qualified products at a lower price (no middlemen to earn profits), on the other hand to ensure the timely after-sales service, no longer through other intermediaries (one to one), can directly find specific personnel to arrange installation and maintenance and other services.



Purchased core materials: The core materials and components of Nitrogen machine (nitrogen manufacturing machine, nitrogen generator, N2(Nitrogen Genertor), are molecular sieve and control valves and PLC, of course, whether the detection instrument is accurate and reliable, is also a key, now the status of this part is described as follows:

Many peers will provide very detailed technical solutions in the competition process, including valves, molecular sieve, meters, PLC,... Just need to attach the material proof of the screw! It feels more authentic than foreign pre-sales services, especially in Europe and the United States. But the opposite may be true, and some things are already an open secret in the industry. The focus is reflected in the most critical system and the highest cost: molecular sieve.

Molecular sieve

Japan Takeda, Germany BF, Japan Iwatani and other imported brands account for almost 98% of the recommended system solutions. According to this reason, domestic molecular sieve manufacturers have long been closed, but in fact, according to the market speculation in 2006, the market share of domestic molecular sieve is about 1100 tons, and the imported molecular sieve is 400 tons. This means that 7 out of 10 equipment that you purchase that indicates the use of imported molecular sieve may be inconsistent with your contract. If you buy equipment with more than 99.95% purity, there will be less chance of similar problems, because domestic molecular sieve in sintering, especially in reaming technology, compared with international excellent brands, there is a big gap, reflected in the production of high-purity nitrogen, its gas production rate, stability and imported molecular sieve compared, can not be guaranteed. So some manufacturers use a part of the import, use a part of the domestic, the specific proportion of how many, some manufacturers use what method, the adsorption tower is larger than the theoretical design, first fully loaded into the imported molecular sieve, and then gradually replaced, until the purity of nitrogen will meet the contract requirements, and then in the detection instrument (detailed later), move some hands and feet, To ensure that nothing is wrong, however, the possibility of completely using domestic molecular sieves for equipment with nitrogen purity less than 99.95% is increased.

Let us not to demonstrate the performance difference between domestic and imported materials is how much, the same product, in different areas will have different prices we should be understandable, but some manufacturers of nitrogen machine on the same specification of nitrogen machine price difference is also happening, in terms of this phenomenon is not very interesting? Imported molecular sieve, foreign high-quality brand accessories finally give you a cabbage price? The equipment has been used for less than a year, the indicators have problems, can not find the original manufacturer to repair? (Dongguan City Troy Gas Equipment Co., Ltd. often receives some maintenance calls from manufacturers in other areas, and the equipment fails shortly after it is on, and then finds us and asks us to arrange the master to repair it.)



PSA Nitrogen machine (nitrogen manufacturing machine, nitrogen Generator, N2(Nitrogen Generator) manufacturing level and the world's excellent brands in the appearance of equipment, energy consumption ratio, performance stability, user-friendly operation... Many aspects of the gap, Dongguan Troy gas Equipment Co., Ltd. in the continuous learning, continuous digestion and absorption, do our best, the best and most advanced PSA Nitrogen machine (nitrogen manufacturing machine, nitrogen Generator, N2(Nitrogen Generator) dedicated to the trust of our users, in order to express our gratitude. With gratitude, you can feel happiness, you can delight people, you can honor and shame, you can go further!
