Abstract
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.
