DPNI is a process that involves replacing the compressor as the source for pressure maintenance gas in dry (pre-action) fire sprinkler systems with a nitrogen generator. Through a process of patented fill and purge breathing the oxygen rich air in the piping is replaced with nitrogen gas using a vent that is attached directly to the fire sprinkler system piping. Once the piping is inerted, the breathing stops and nitrogen gas is used to maintain the pressure within the piping. DPNI completely prevents oxygen corrosion within the fire sprinkler system.
