Based in the industrial hub of Jiangyin City, Jiangsu Province, Jiangyin Longyao Machinery Manufacturing Co., Ltd functions as a specialized manufacturer of air separation and gas purification equipment. The company concentrates on the research, development, and production of on-site gas generation systems, utilizing Pressure Swing Adsorption (PSA) technology to serve a variety of demanding industrial applications. While its engineering capabilities extend across multiple heavy industries, the type of machinery produced by the company holds significant relevance for the maritime and offshore sectors, where self-sufficient gas supply is often a critical operational requirement.
The core of the company’s manufacturing identity lies in its advanced PSA nitrogen and oxygen generation systems. In the context of maritime operations, nitrogen generation is a vital safety protocol, particularly for chemical tankers, LNG carriers, and offshore supply vessels. The equipment engineered by Jiangyin Longyao is designed to separate nitrogen from compressed air using carbon molecular sieves, a process that provides a continuous flow of high-purity inert gas. This capability is essential for marine inert gas systems, which are used to blanket cargo holds, purge tanks of volatile vapors, and prevent combustion events at sea. The company’s systems are engineered to achieve high purity levels, reaching up to 99.999 percent, ensuring that the nitrogen generated meets the stringent safety standards required for handling hazardous marine cargoes or preserving sensitive goods during transit.
Beyond nitrogen, the company manufactures PSA oxygen generators, which utilize zeolite molecular sieves to isolate oxygen. Within the marine sphere, such technology allows vessels to maintain autonomous oxygen supplies for medical bays, welding maintenance, or specialized life-support environments without relying on the logistical complexities of replenishing high-pressure cylinders at port. Jiangyin Longyao integrates these core technologies into comprehensive air purification and high-purity extraction solutions, emphasizing electromechanical design that supports rapid startup times and efficient operation.
With over a decade of experience in air separation manufacturing, the company operates with a focus on technological innovation and rigorous quality control. Its facility in Yuecheng Town supports a production philosophy centered on reliability and lifecycle service, ensuring that the equipment can withstand the continuous operation required in remote or harsh environments. By delivering robust gas generation solutions, Jiangyin Longyao Machinery Manufacturing Co., Ltd plays a supportive role in the broader infrastructure that enables safe and self-reliant industrial and marine operations.
