A colleague of mine went to the demo not a tech guy. The pressure is 1800 psi. Distribution piping is small I.D. Stainless Steel with compression type fittings. N2 cylinder. 208 cubic ft at 2300 psi. You may be able to retro fit a hotel and save some $ I don't see this as competitive in new construction or SFD.

While I expect pressures (operating) to be higher for mist systems, I can see the benefit of very small high pressure tubing in some type of wire mold in an existing structure. The $100,000.00 savings is somebody blowing smoke up you know where, or they inhaled more than once. The largest 13D system we ever did was 44,000 SF and it was about a $50K job. So unless the average home is now 250,000 SF I don't see any way even at half the cost to save 100K. I love the statement 13R for single family and duplex homes in the copy of Gannon's study. Obviously Marriott is more in keeping with 13R, in their retirement and lodging settings. Personally I think there is more to be studied, and perhaps something that looks more like a "Vortex" system will come of it someday. Right now unless someone is volunteering their community to be a Guinea Pig for this mist system, I don't see its application as a option in 13D or R very soon. Of course you could always do it a "Equivalent" engineered design. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.
