Nitrogen Systems

Nitrogen systems are used to prevent and inhibit corrosion in dry systems and preaction systems with supervisory gas in system piping.

Dry and preaction systems employing supervisory air are subject to corrosion, which may lead to property damage, ongoing pipe repair and replacement, system downtime, and decreased c-factor and sprinkler blockage. Replacing air and oxygen in a sprinkler system with nitrogen inhibits corrosion by removing a segment of the corrosion triangle.

Reliable offers a variety of nitrogen systems, including the PrePaK Dry and Preaction Cabinet with integrated N2-Blast generator.
