I understand that a "Vortex" fire suppression system has been proposed for some areas of a new facility our museum is planning (to house diverse collections of humanities, archival and natural sciences material including some particular areas of concern for fire suppression such as alcohol preserved collections and potentially unstable early plastics). I understand this "Vortex" system uses a combination of compressed nitrogen and water mist. I am aware that users of "dry pipe" type systems have reported problems with corrosion developing in the pipes. I would be interested in hearing from other museums that use this system about the pros and cons and whether we should be advocating for or against choosing this system.
