Most enterprises that purchase large-scale nitrogen generation units often encounter two core problems: Firstly, the nitrogen purity of the equipment does not meet the standards, resulting in inability to start production, delays in the construction schedule, and the need to install purification equipment and undergo secondary renovations at their own expense, thereby increasing additional costs; Secondly, the multiple links of procurement, installation, commissioning, and after-sales service are chaotic, the acceptance process is cumbersome, and this seriously affects the project progress. The manufacturer of Hengda nitrogen generation equipment guarantees the three major hard standards to efficiently solve the industry's procurement pain points: Firstly, all parameters such as nitrogen purity, flow rate, and operational stability are all contractually locked, with clear regulations for rectification when not meeting standards and compensation details, ensuring clear rights and responsibilities and guaranteeing security; Secondly, the unit must undergo 72-hour full-load continuous commissioning before leaving the factory, replicating the production peak conditions, and can only be shipped when the parameters are stable and meet the standards; Thirdly, the professional team will conduct on-site installation and re-testing, and if the purity does not meet the standards, free debugging and optimization will be provided, without the need for enterprises to undertake secondary renovations. The equipment relies on self-developed PSA nitrogen generation technology and strict quality inspection to support full-range purity customization from 95% to 99.9995%, and can be inspected and qualified on-site, significantly shortening the production start-up cycle and ensuring the stable supply of gas to the production line.
