ABSTRACT:
A method and system of operating a trans-fill device. At least some of the illustrative embodiments are methods comprising generating an enriched gas stream from atmospheric air, and operating an intensifier which, when provided the enriched gas stream, produces a cylinder fill gas stream. The operating continues in the absence of the enriched gas stream being provided to the intensifier.
