The company holds 20+ patents, including a national patent for the world's first plateau train membrane oxygen system used on the Qinghai-Tibet Railway, with cumulative deployments exceeding 1,500 units across 20+ industries including rail transportation, state grain reserves, glass manufacturing, biogas upgrading, environmental water treatment, and medical oxygen supply.

The company's business model is project-based custom equipment sales with no list pricing, targeting enterprise and government customers primarily through direct sales from its Dalian headquarters supported by eight regional service offices across China (Changchun, Shenyang, Qingdao, Chengdu, Wuhan, Xining, Lhasa, Kunming). It is an approved supplier to China Railway and Sinograin (China Grain Reserves Corporation), with flagship deployments of 500+ railway oxygen units across the Qinghai-Tibet and Lhasa-Linzhi lines and grain depots across 14+ provinces. The company restructured into a joint stock company in August 2016 and listed on China's New Third Board (NEEQ). Revenue is generated through custom equipment contracts with state-owned enterprises and industrial buyers, with long product lifespans supporting recurring after-sales service revenue.
