Patent number: 10420970Abstract: A fire protection system includes a dry pipe system and a controlled discharge gas vent. The dry pipe system and controlled discharge gas vent operate using a breathing cycle to displace oxygen and/or water vapor from within the piping network of the dry pipe system. The controlled gas discharge vent allows displacement of pressurized air with nitrogen, for example, using manual or automated processes that can employ one or more sensors. Corrosion resulting from oxygen, water, and/or microbial growth is reduced or nearly eliminated.Type: GrantFiled: March 6, 2017Date of Patent: September 24, 2019Assignee: Engineered Corrosion Solutions, LLCInventors: David J. Burkhart, Jeffrey T. Kochelek, Kenneth Jones, Thorstein Holt

Publication number: 20190143161Abstract: A fire protection system comprising at least one sprinkler, a source of pressurized water, a piping network connecting at least one sprinkler to the source of pressurized water, and a nitrogen generator coupled to the sprinkler system. The nitrogen generator may be a nitrogen membrane system or a nitrogen pressure swing adsorption system. The present systems and methods reduce or nearly eliminate corrosion that typically affects conventional fire protection systems, such as caused by oxygen and microbial systems, which can deteriorate or compromise function. Initial, repeated, or continuous displacement of oxygen with nitrogen in the fire protection system significantly reduces or eliminates corrosion.Type: ApplicationFiled: January 15, 2019Publication date: May 16, 2019Inventors: David J.
