Nitrogen generator

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

Kerong Gas has successfully provided a state-of-the-art carbon-based nitrogen purification system to the Nanofiber Materials Laboratory at Wuhan University of Science and Technology, meeting their strict requirement for ultra-pure and ultra-dry nitrogen. The system was specifically chosen to purify nitrogen from gas cylinders to an extraordinary purity level of 99.9998%, with an ultra-low dew point

To ensure the highest quality standards, our engineers are conducting the final factory tests on the nitrogen gas generation plant before shipment. With compressed air available in our workshop, the unit is undergoing a thorough gas leakage inspection and performance evaluation. Once the machine successfully passes all tests, the 60 Nm³/hr, 99.99% purity nitrogen generator

We are proud to announce that on March 14, 2025, Kerong Gas officially received the Special Equipment Production License. This certification recognizes our capability and authorization to install, repair, and modify pressure-bearing special equipment. Achieving this milestone reflects our commitment to quality, safety, and compliance with industry standards. It reinforces our ability to deliver reliable

We supplied our PSA nitrogen plant in July 2023. The end user began installing and commissioning the plant in December 2024. They received a complete package, including a 55 Nm³/hr PSA nitrogen generator, a 50 Nm³/hr nitrogen purification unit, and a small ammonia cracker with a purifier to provide a hydrogen gas source for the

We recently assisted our heat treatment client in the Middle East with the successful commissioning of their nitrogen station. Here’s a video showcasing the machine in full operation after everything was set up and running smoothly.

Kerong Gas recently received an order from a customer for a nitrogen gas recovery machine. The end user, a copper processing factory, uses cryogenic nitrogen gas in their operations. To save energy, they decided to recycle the waste nitrogen gas. The original purity of the waste gas is 900Nm3/hr @ 97% and it contains oil
