What are the domestic manufacturers of liquid nitrogen tanks?

At present, there are many manufacturers and models of liquid nitrogen storage tanks at home and abroad, but there are still some developed and concentrated places. For example, in Chengdu, Sichuan and Xinxiang, Henan, the state-owned enterprises in these two places were the first two pilots to introduce foreign technology in the early days of China's reform and opening up. At present, domestic brands that independently or OEM produce liquid nitrogen containers are mostly concentrated in these two places. After the transformation, enterprises in these two regions have developed into independent brands, and there are many manufacturers. Other areas are scattered, such as Shenyang, Zhengzhou and Leshan, but the manufacturers are few, scattered and famous. At present, Xinxiang City, Henan Province has many manufacturing enterprises such as Si Nuo Cape, Yuxin Airlines, Xinya, Pailite and Tianchi (Zhengzhou City). There are many manufacturing enterprises in Sichuan, such as Chater (also called Jinfeng), Li Shan, China Fire and Rong Fei. In addition, Leshan has Asia, West and East Asia, and Shenyang has a new Yuguang.
