No membrane pressure vessel.

The expansion is at  atmospheric pressure which not only minimises the expansion vessel size, but also allows the pressure step de-aeration process. 

No membrane in  the vessel means no gas pressure to maintain, no membrane to replace

Free and dissolved gases or air bubbles, formed during system filling and  absorbed from parts of the heating system are removed using this unique  de-aeration device.

Opening a mineral water bottle produces gases which  were dissolved in the water, the Olymp Automat uses the very same  principal to remove from the installation all aggressive and destructive gases even from remote areas of the system.  See Henry's Law -   adiabatic gas separation.
