As a supplier focusing on the research and development of gas equipment applications, Jiangyin Rongchen provides users with nitrogen generators, oxygen generators, and purification devices. In the petroleum field, Rongchen provides users with ideal gas production solutions based on its many years of experience and patented technology.

Pharmaceutical nitrogen generators are mainly used in the fields of pharmaceutical production, storage, packaging, and packaging. Medical nitrogen equipment (nitrogen purity 99.99%) is based on the experience of focusing on pressure swing adsorption nitrogen generators for nearly 20 years. The pharmaceutical nitrogen generators developed in accordance with GMP specifications have operating costs compared with cylinder nitrogen (or liquid nitrogen). Low, stable nitrogen purity, easy to use.

Rongchen’s food storage and liquid nitrogen-filled fresh-keeping technology is at the forefront of the industry. Our equipment covers all major granaries in the country, which effectively inhibits the survival of pests and diseases in the process of grain storage. Our nitrogen sealing technology has been used in the beer and food packaging industries. Widely used, the introduction of nitrogen sealing technology has greatly extended the product preservation cycle and relieved users of the worries caused by unsalable products. Nitrogen generators in the food industry are suitable for grain green storage, food nitrogen-filled packaging, vegetable preservation, wine sealing (canning) and preservation, seafood preservation, insect control, nitrogen sealing, etc.

R.CHEN’s nitrogen vulcanization process technology has replaced the traditional superheated vulcanization process and has achieved success in the tire rubber industry. The advantages of nitrogen vulcanization technology are: • Reduce the investment in public works necessary for the steam generation process, and at the same time reduce NOX and COX emissions, to achieve the purpose of energy saving, emission reduction and environmental protection; • Nitrogen vulcanization process is stable, reducing lack of rubber, delamination and bubbles in tire vulcanization, and improving tire quality; • Low heat loss, save energy and reduce costs; • High-purity nitrogen removes the premature aging and damage of the vulcanizing capsule under the action of oxygen, and the capsule use time is extended by 25-50%, saving equipment use and maintenance costs; • Improve product quality, and tire performance indicators have been improved in mileage, durability, uniformity, and press-through ability; • Easy to use, the pressure can be adjusted within a certain range, and the pressure rise time is short; • Nitrogen can be recycled, with a recovery rate of about 40%; The special nitrogen generator for the rubber tire industry is suitable for the fields of nitrogen protection and molding in the vulcanization process of rubber and tire production. Especially in the production of all-steel radial tires, the new nitrogen vulcanization process has gradually replaced the steam vulcanization process, with high nitrogen purity , Continuous production, high nitrogen pressure, etc.

Nitrogen blanketing, purging, replacement, cleaning, pressure conveying, chemical reaction agitation, chemical fiber production protection; synthetic fiber nitrogen filling pressure material, drawing anti-oxidation and other fields.

Rongchen's high-purity series products are suitable for various process requirements. Purified hydrogenation type A, energy-saving type, purified C type, and carbon combustion type are various solutions specially developed for electronics and semiconductor users, which are convenient for users to choose. , In particular, energy-saving purification has obtained a variety of patented technologies, providing on-site solutions for users who require higher purity nitrogen (oxygen content ≤1ppm, hydrogen content ≤1ppm) to meet high-quality production of electronic products. It is suitable for semiconductor production and packaging, electronic component production, LED, LCD liquid crystal display, lithium battery production, nitrogen shielded welding and other fields.

When the full oxygen aeration activated sludge process adopts full oxygen aeration, the growth rate of dissolved oxygen is about 8-10 times that of air aeration, which can significantly increase the oxygen transfer rate, increase the sludge concentration, and improve the sludge settling performance , It is especially suitable for the denitrification upgrading and transformation of existing activated sludge treatment plants. Water with low oxygen concentration often contains hydrogen sulfide and other malodorous substances, which are a greater threat to humans. The use of microbubble oxygen-enriched aeration can convert sulfide into non-toxic thiosulfate or sulfate, which can be used in water channels and rivers. The reoxygenation of the surface water in, lakes and artificial reservoirs.

With the continuous updating of glass products, the production processes of float glass, containers, flat plates, optical fibers and special glass products are gradually upgraded, and the demand for industrial gases has also increased. Rongchen’s oxy-fuel technology and supporting oxygen supply system have gradually matured in the glass manufacturing industry. The oxy-fuel technology has been applied to the glass manufacturing industry. Compared with traditional air-based combustion, it greatly increases the heat of combustion and optimizes the quality of users’ products. Improve product productivity, reduce combustion impurities, extend the use time of combustion furnaces, and the oxyfuel combustion technology is more energy-saving and environmentally friendly. Nitrogen is mainly used in the glass industry to prevent surface oxidation in the glass manufacturing process and to cool the heating furnace.

Nitrogen is an ideal basic gas that can be used in a heat treatment atmosphere, and it is inert to most materials. Nitrogen and other reactive gases such as hydrogen, mixed in the best ratio, are generally used in situations that require high purity, such as vacuum Heat treatment gas quenching process, general heat treatment process of welding furnaces in the electronics industry and high-value products or materials. The special nitrogen generators for the metallurgical industry are mostly suitable for heat treatment, bright annealing, protective heating, powder metallurgy, copper and aluminum processing, and magnetic materials Sintering, precious metal processing, bearing production and other fields. It has the characteristics of high purity, continuous production, and some processes require nitrogen to contain a certain amount of hydrogen to increase brightness.
