In recent years, "fresh" has become a divine object pursued by various industries, and the beauty and plastic surgery industries have also tried to create "frozen age beauty". However, there are more things in life we want to keep that "fresh and tender", fruit, fish will still appear wrinkled in the refrigerator, Chinese medicine, Western medicine injections also need to be fresh preservation, especially in recent years, the development of science and technology, all kinds of electronic components once oxidation rust loss is immeasurable.
All these "preservation" secrets, but there is a magic pill - nitrogen can solve.
In order to prevent some objects from being oxidized by oxygen when exposed to the air, filling the granaries with nitrogen can make the grain not moldy, not germinating, and long-term preservation. Nitrogen-filled storage and fresh-keeping of fruits, vegetables and tea is also a most advanced method. This method can make fruits, vegetables, vegetable leaves, etc. in a high nitrogen and low oxygen environment, slow down metabolism, as if entering a hibernation state, inhibit post-ripeness, so as to keep fresh for a long time. According to the experiment, the apples stored with nitrogen are still crisp and refreshing after 8 months; The Zhou black duck that we often eat can be kept delicious and fresh within a week by nitrogen locking.
In the production process of electronic components and semiconductor components, nitrogen with a purity of more than 99.999% needs to be used as a protective gas. At present, high purity nitrogen has been used as carrier gas and protection gas in the production process of color TV picture tubes, large-scale integrated circuits, liquid crystals and semiconductor silicon wafers.
"One-stop gas service expert" Troy engaged in gas service for many years, because nitrogen is non-toxic, relative to food preservation, electronic components anti-oxidation, metal processing gas protection, chemical fiber synthesis and other industry needs, is very safe. Therefore, the nitrogen machine used to separate nitrogen is also widely favored by these industries.

Troy technician pointed to the company's production of pressure swing adsorption nitrogen machine device said, "This is a new type of air separation of high-tech equipment, compressed air as raw material, carbon molecular sieve as adsorbent, using pressure swing adsorption process to produce nitrogen."
At normal temperature, using the difference in adsorption amount of air weight oxygen and nitrogen on the surface of carbon molecular sieve and the difference in diffusion rate of oxygen and nitrogen in carbon molecular sieve, the programmable controller is used to control the start and close of the pneumatic valve to realize the process of pressure adsorption and decompression desorption, complete the separation of oxygen and nitrogen, and obtain the required purity nitrogen.
The full implementation of "one-stop gas service experts" to solve problems in the shortest possible time for each customer is Troy's goal. It indicates that the purity and gas production of nitrogen in the separation of the nitrogen machine can be adjusted according to customer requirements. And this nitrogen machine according to customer requirements of high purity nitrogen, you can support the nitrogen purification device produced by Troy behind the nitrogen device, purity of up to 99.9999%, dew point of -70℃, nitrogen content of 1ppm of high purity nitrogen.
Troy produces industrial gas equipment with its advanced technology, excellent quality, Reasonable price and valuable after-sales service are widely used in steel industry, air separation industry, heat treatment industry, natural gas industry, and powder metallurgy, mesh furnace, bell furnace bright annealing, petrochemical, chemical fiber, glass, food preservation, medicine, electronics, offshore oil development, storage and shipping, defense and aerospace and other leading fields.
