Hangzhou Kejie Environmental Protection Technology Co., Ltd. is a leading liquid nitrogen generator PSA manufacturer, supplier, and factory in China. Our PSA technology for the production of liquid nitrogen is a more efficient way of generating nitrogen from an atmospheric mixture, which can be used for food preservation, metal treatment, pharmaceuticals, laser cutting, and more.
Our liquid nitrogen generator PSA technology employs the use of carbon molecular sieves (CMS) to separate nitrogen and oxygen. The CMS has a higher affinity for oxygen than nitrogen, and as the air enters the adsorption column, oxygen is captured while the nitrogen passes through to the storage tank, where it's stored at a pressure of 5-6 bar.
The generator operates on low energy consumption, and it's easy to use with minimal maintenance. We offer our clients customized liquid nitrogen generator PSA solutions to meet their specific requirements, ensuring that you get the best value for money. Choose us for reliable, high-quality liquid nitrogen generator PSA systems that offer excellent performance and cost savings.
