In Heartwork, four Nanocentrifuges with nanite clouds appear in four separate Chinese outposts. All of them must be destroyed by the player-controlled Russians.
In Thread of Dread, Machinehead and Blood Rage, Nanocentrifuges are present in Foehn bases. Unlike the ones in Heartwork, these Nanocentrifuges have no nanite cloud and serve no gameplay purpose. In Blood Rage, the Nanocentrifuges in the Foehn base will disappear once Foehn forces abandon the area.
