The big packaging containers of our specialty gases include bundles, Y-cylinders, drums, tube trailers, and ISO tanks (you may refer to Products/Specialty Gases on our website). Therefore, the construction of bulk special gas systems (BSGS) has always been one of the strengths of Jing He Science, especially the patented water cycling ISO tank heating system for NH3 that can offer you a stable and safe specialty gas supply, greatly reducing the labor workload and operating risk of frequent cylinder replacement.
