Yes we have many dry systems. I have never seen one which does not have a pressure regulator and an adjustable PRV. Most of the adjustable PRV's are set to relieve any pressure which is 10-15 psi above the set pressure.

I'm guessing there's gotta be a few dry systems down there in unheated warehouses with extreme temp swings. So in these systems with 100% air, do you find the pressure above the dry valves climbing to extreme levels in the summer?
