The GNV59-400 refers to a PSA nitrogen generator in the V series. It can produce nitrogen with a purity of 99.999% and has an output capacity of 400 Nm³/h. Following rigorous appraisal by experts convened by Shandong’s Department of Science and Technology, Department of Industry and Information Technology, and other relevant authorities, its application project has been certified as a Shandong Province First Set Technical Equipment, with its air-nitrogen ratio conversion technology rated at the international advanced level.

This achievement is highly significant. demands strict compliance with criteria:
1. products must demonstrate significant technological innovation, hold independent intellectual property rights (with no pending disputes).
2. meet stringent quality and safety standards—including passing testing by nationally accredited laboratories or recognized industry institutions.
3. Specialized products must also secure necessary regulatory approvals, such as production licenses or mandatory certifications.

                                                         
Earning this recognition indicates that the GNV59-400 not only demonstrates outstanding performance in technological innovation and performance indicators, surpassing domestic counterparts, but also achieves a leading position in the international arena in terms of air-nitrogen ratio conversion technology. It represents a major breakthrough in independent control of key core technologies, breaks through foreign technological monopolies, and also entitles the product to a series of preferential policies in Shandong Province, such as financial subsidies, market promotion support, and tax incentives. This will greatly enhance the brand influence and market competitiveness of the enterprise, playing a crucial role in promoting technological progress in the entire industry.
