Kerong Gas has made significant advancements in pressure swing adsorption (PSA) technology for nitrogen production. Traditionally, PSA systems are capable of delivering nitrogen gas with a maximum purity of 99.999%. However, through our innovative design and the use of advanced carbon molecular sieve (CMS) filling techniques, our system can reliably achieve nitrogen purity levels up

In this July 2025, Kerong Gas delivered a second hydrogen gas recovery system to a steel annealing factory, following the customer’s satisfaction with the first unit installed three years ago. This repeat order reflects the reliability and performance of our technology. Additionally, two nitrogen gas generation systems are now en route to a semiconductor factory

We are proud to announce that Henan Kerong Gas Equipment Co., Ltd. has officially received the CE Certificate of Conformity for our KRN, KRNA, and KRNAB series nitrogen generators. This certification, issued by Ente Certificazione Macchine (ECM), confirms that our equipment complies with EN ISO 12100:2010 and EN 60204-1:2018+A1:2025 standards, meeting essential requirements under the

Kerong Gas has successfully dispatched two 200Nm³/h nitrogen generation systems (99.9995% purity) to a major electronics and semiconductor facility in Suzhou. These systems replace traditional liquid nitrogen use without needing additional purification equipment, helping the customer cut gas costs significantly. Key benefits include one-step nitrogen production, fully automatic operation, remote monitoring, and low maintenance—with only
