10 YEARS
Sprinkler systems have one job, and failure to perform has catastrophic consequences. While a well-maintained sprinkler system protects your people and your property; corrosion compromises that safety, rendering over 50% of dry systems to not operate as intended after only 10 years.
Protecting your new system or retrofitting your existing system with nitrogen protects against corrosion, adding decades to the life of your sprinkler system, reducing costly replacements, maximizing system safety and delivering greater confidence in optimal system performance over time.
Protection is a long game; we help you go beyond

KEY FEATURES
South-Tek System’s N2Blast nitrogen generator inhibits the risk of corrosion build up, which restricts water flow and can render a system inoperable. The South-Tek solution ensures your sprinkler system works when you need it.
Inhibits multiple causes of in-pipe corrosion and ice buildup
Peace of mind with remote monitoring (select models)
Touchscreen control display for easy handling
Accommodates new system installs or existing system retrofits to extend system life
Manufactured, with pride, Wilmington, NC, USA
Protecting your sprinkler system with nitrogen increases safety and optimizes performance, adding decades to the life of your system with a much smaller investment than the cost of a system failure and replacement.

The Corrosion Triangle
Corrosion is a result of three elements coming together; unprotected metal, oxygen and water. The N2Blast nitrogen generator for dry fire sprinkler systems removes oxygen from the equation, disrupting the process and inhibiting corrosion.
UNPROTECTED METAL
Leaving black steel pipes unprotected results in wall-thinning corrosion that can lead to perforations. Unprotected galvanized steel can lead to pitting – slowing your fire-prevention system down or causing a leak.
OXYGEN
If powered with oxygen instead of nitrogen, there is as much oxygen in your pipes as in the air you breathe. This creates a perfect environment for corrosion.
WATER
Moisture left behind after hydro tests doesn’t completely evaporate from your sprinkler system. These residual water electrolytes further feed corrosion.
UNPROTECTED METAL + OXYGEN + WATER = CORROSION
Extend the Life of a Dry Sprinkler Fire Protection System
The Bottom Line: Protecting your dry fire sprinkler system with nitrogen is worth it. Science says so.
A long-term exposure test found that pipes protected with 98% nitrogen instead of compressed air for dry fire sprinkler systems results in:
Increased life expectancy of black steel pipe systems from 20 years to 63 years.
Increased life expectancy of galvanized steel pipe systems from 10 years to 176 years.

FAQs for Nitrogen-generated Dry Sprinkler Systems
In dry sprinkler systems, pressurized nitrogen or air keeps water at a riser, which isolates the water supply from the sprinkler pipes within a building, keeping pipes dry. Using nitrogen or air instead of water can prevent frozen sprinkler pipes in environments with colder temperatures. The heat from a fire activates sprinklers when surrounding temperatures reach a certain set point, opening the dry valve and releasing the flow of water. In a wet sprinkler system, pipes are filled with pressurized water which is immediately discharged in the event of a fire.
In addition to the invaluable human dangers and damages associated with system failures of existing or rapidly deteriorating systems, the cost of an emergency or a replacement system would far exceed the cost of a nitrogen-generated dry sprinkler system. For example, it may cost you $50,000 to install a nitrogen-generated system, but a total sprinkler replacement, including all of the ancillary equipment could cost you $1,000,000.
Corrosion is a result of combining unprotected metal, oxygen and water. When using a nitrogen-generated dry sprinkler system, oxygen is replaced with 98% pure nitrogen, which inhibits corrosion and promotes system longevity and reliability.
Dry sprinkler systems are used in a number of applications in environments where freezing is possible, including but not limited to unheated buildings, parking garages, loading docks, stadiums, data centers, commercial freezers, external building canopies and warehouses.
Nitrogen-generated dry sprinkler systems are protected with pressurized nitrogen, keeping the water supply isolated from sprinkler pipes for optimal operation in colder temperatures that carry risk of freezing. Oxygen contributes to corrosion; 50 percent of dry systems powered by air do not operate as intended after only 10 years. Using nitrogen in your system instead of compressed air reduces corrosion, adding decades to the life of a sprinkler, maximizing system safety and optimal performance over time.
