Filling begins when the pressure balance between tank and bottle is reached thanks to the activation of a pneumatic CO2 injection valve. The filling stops when the liquid reaches the air return spout; the valve can therefore be closed. Subsequently a further pneumatic device controls the decompression phase to guarantee absence of turbulence and foam when the bottle comes out of the machine.

The tank, the valves and all the parts in contact with the product are mirror polished and slightly inclined to avoid dirt residues and facilitate washing and drainage, which can be carried out with liquid, cold and hot solutions. Sanitization is controlled automatically by the machine control program and is activated by electro-pneumatic devices.
