The HUILIN Medical Molecular Sieve Oxygen Production System adopts PSA pressure swing adsorption oxygen generation technology, mainly composed of multiple molecular sieve oxygen generation hosts, oxygen compressors, oxygen filling systems, and supporting intelligent control units. Multiple oxygen generators are connected in parallel, and the oxygen production scale can be adjusted as needed to ensure the continuity of oxygen supply. A single failure does not affect the operation of the entire system. The oxygen compressor can complete the filling of oxygen cylinders through the filling system, and the oxygen cylinder becomes a backup gas source. Realize the integration of on-site oxygen production, pipeline gas supply, and steel cylinder filling. The entire equipment is equipped with online monitoring and alarm functions, which can monitor oxygen purity, pressure and other parameters in real time, and can operate continuously and stably for 24 hours.
