Engineered Corrosion Solutions, LLC and Potter Electric Signal Co., LLC Reach License Agreement
St. Louis, MO February 15, 2018, Engineered Corrosion Solutions and Potter Electric Signal Company announce a license agreement for Potter to practice the use of ECS patents 9,186,533 and 9,144,700, which disclose the use of a nitrogen generator with a vent on dry pipe and preaction fire sprinkler systems.
Nitrogen Generator used to inhibit corrosion:
The nitrogen generator can be used in place of a conventional air compressor for pressurizing the piping network with nitrogen and maintaining a “supervisory” or system pressure until the sprinkler system is actuated (e.g., by fire). The vent allows gas, in particular oxygen displaced by the nitrogen, to exit the piping network while maintaining the system pressure. The nitrogen generator combined with the vent removes trapped air and decreases the concentration of oxygen in the piping network to inhibit corrosion, including microbiologically influenced corrosion (“MIC”) and oxygen cell corrosion.
