N2-Blast® – Corrosion Inhibiting System
Internal corrosion of sprinkler pipe is one of the foremost issues facing the Fire Protection industry. It leads to costly and extensive pipe repairs that can shut down or delay production in a manufacturing setting, reduce usable space in garage and warehouse settings, and force relocation of tenants or patients in residential and hospital settings. Corrosion leads to the formation of localized pinholes and the resulting sprinkler pipe leaks can cause catastrophic property and equipment damage in facilities such as data centers and museums. More importantly, internal corrosion can cause sprinkler head blockage, reduce flow rates, and render fire protection systems completely inoperable in the event of a fire – leading to loss of life and property.
Introducing the N2-Blast® – Corrosion Inhibiting System, recipient of the coveted NACE Corrosion Innovation of the Year Award. The N2-Blast® – Corrosion Inhibiting System generates and introduces up to 99.9995% pure nitrogen into the dry or preaction fire protection system. In doing so, oxygen, a key contributor to the corrosion reaction, is displaced from the piping through the AutoPurge System™. The N2-Blast® effectively inhibits Electrochemical, Galvanic and Microbiologically Influenced Corrosion (MIC), as well as sprinkler pipe ice plugs. Take action by displacing trapped moisture and oxygen from within the sprinkler piping with the N2-Blast® and help ensure that your fire protection system works effectively in the event of an emergency.
