Shenzhen Jinbao Electromechanical Equipment Co., Ltd. has been officially granted a utility model patent for its “High‑Efficiency Energy‑Saving Modular Nitrogen Generation System” by the National Intellectual Property Administration (publication number: to be added; filing date: Month 2025).

This patent relates to the technical field of nitrogen generation equipment. Unlike traditional integrated fixed‑architecture systems, the patented design uses a distributed independent modular structure – multiple nitrogen‑producing units can operate independently or in parallel. Users can flexibly activate the required number of modules based on real‑time nitrogen demand, avoiding the waste of venting large amounts of qualified nitrogen when demand is low.

Field tests show that at 50% load, the system saves 15‑20% energy compared to conventional fixed‑speed nitrogen generators. When paired with an INOVANCE VFD air compressor, intelligent load matching and on‑demand air supply can achieve overall energy savings of more than 30%. In addition, the patented system is equipped with a Xinje PLC‑based multi‑point closed‑loop control that monitors purity and pressure in real time, ensuring nitrogen purity stays within the 99%–99.999% range. It automatically vents and alarms if purity falls below the set point, significantly improving operational reliability and safety.

The technology has already been fully integrated into Jinbao’s A‑Series and X‑Series modular nitrogen generators and can be flexibly extended to the Integrated Series. Jinbao Machinery will continue to drive energy efficiency upgrades and intelligent development of nitrogen generation equipment, using this patent as a new technical milestone.
