Cryogenic Liquid Nitrogen Systems
Cryogenic liquid nitrogen systems is a high-end industrial gas solution developed by Shenger Gas based on cryogenic air separation technology. The system can stabilize the production of liquid nitrogen at -196℃ through air compression, pre-cooling, distillation and other processes. The cryogenic liquid nitrogen systems are particularly suitable for industrial scenarios that require ultra-low temperature environments and large-scale gas storage. The entire system complies with the ASME BPVC pressure vessel standard and ISO 8943 low temperature equipment specifications.
