Dry fire sprinkler systems are lifesavers, but they require careful maintenance, especially when filled with compressed air. Traditional air can cause corrosion in the pipes over time, leading to leaks and potential failure. Nitrogen generators offer an alternative, but are they worth the investment?

Pros of Nitrogen Generators

Reduced Corrosion: Nitrogen is an inert gas, meaning it doesn't react with other elements like oxygen. This significantly reduces corrosion in the pipes of your dry sprinkler system. Studies show a lifespan increase of up to 60 years compared to 15 years with compressed air!

Lower Maintenance Costs: Less corrosion translates to fewer repairs and replacements. You'll also save on leak checks, as nitrogen is less prone to leaks.

Cost-Effective in the Long Run: While the upfront cost of a nitrogen generator is higher than a traditional air compressor, the long-term savings on maintenance and potential system replacement can outweigh the initial investment.

Environmentally Friendly: Nitrogen is the primary component of air, making it an eco-friendly choice. There are no harmful chemicals involved.

Better Pipe Options: With nitrogen, you can use less expensive black steel piping instead of galvanized steel, which is more susceptible to corrosion from compressed air.

Cons of Nitrogen Generators

Upfront Cost: Nitrogen generators require a significant initial investment compared to compressed air systems.

Power Source: Generators require a constant power supply to function. A power outage could compromise your fire suppression system if there's no backup.

Not Always Necessary: For smaller dry sprinkler systems or those in controlled environments, the benefits of nitrogen might not outweigh the costs. Compressed air with a good air dryer system can still be effective. Many times these are used in systems that span between conditioned and non-conditioned spaces.

Deciding on Nitrogen Generators

Nitrogen generators are a smart choice for large or critical dry fire sprinkler systems, especially those in buildings with long lifespans. They offer significant cost savings over time through reduced maintenance and potential system replacement. However, for smaller systems or those on a tight budget, compressed air with proper drying systems may be sufficient. Consulting with a fire protection professional can help you determine the best option for your specific needs.
