Ray Fremont Jr., president of General Air Products, joins Drew to talk about the air supply side of dry pipe sprinkler systems. General Air Products has been building air compressors for fire sprinkler systems since the 1960s, and the Fremont family has been in the compressed air business since the 1930s. Ray covers how dry system air supply has changed over the last century: plant air compressors and schedule 40 pipe, the shift to thin-wall steel, nitrogen generators, and a newer vapor corrosion inhibitor technology called Vapor Pipe Shield that creates a molecular barrier on the inside of the pipe. They also dig into some real problems: most dry systems leak well beyond what NFPA 25 allows, jurisdictions are a decade behind on code adoption, and air compressor maintenance still gets skipped. Ray previews a new digital monitoring device that tracks compressor cycling and flags system issues before they turn into failures. It's the kind of predictive data the sprinkler side has never had.
