Below is a simplified configuration related to a system for filling cylinders with a single compressed gas.
For filling mixtures with two or more gases, the plant would provide several separate and independent streamlines, each of which would have either an additional pumping and gasification system, or a compressed gas or gas mix supply, from cylinder, cylinder packs, or tank cars. In this case, all ingredient gases would flow into a special mixture filling panel, located downstream of the DSP switchboards and upstream of the filling station, equipped with all the necessary devices so that no gas refluxes to the various distribution systems are allowed, as well as any safety solutions to handle, where present, stations with multiple final filling pressures (e.g., 200 and 300 bar nominal).
Example of a simplified system for filling cylinders with compressed gas:

Cryogenic fluid storage tank
Pumping unit and related electrical control panel
One or more ambient heat exchangers, better known as ambient vaporizers, possibly followed in series by electric exchangers (plate or water type)
Safety device to protect plant and receiving cylinders
Compressed gas distribution line
Distribution ramp with cylinder filling stations
In-fill receptacles
Not depicted in the figure:
- Valve box with delivery lines from the latter to the various filling stations
- System for analyzing the purity of the product fed into the cylinders, with associated sampling circuit, consisting of at least a sampling valve, a reducer, and a sample flow supply line to the analytical system.
