IG‑55 systems utilize Argonite™, a 50/50 blend of nitrogen and argon, to suppress fires by reducing oxygen concentration within protected spaces. This clean, residue-free agent is non-toxic, non-conductive, and ideal for safeguarding sensitive environments such as data centers, control rooms, archives, and museums where water or chemical extinguishers would be unsuitable .
Kidde’s Natura™ IGS IG‑55 cylinders are fabricated from seamless steel, comply with ISO 9809‑2, and carry TPED/UN/DOT certification. They come in 80 L or 140 L sizes at 200 bar or 300 bar, equipped with high-pressure valves, burst discs, anti‑recoil and transport caps for safety and durability. The system uses Kidde’s Series 400 valve to regulate flow and pressure—allowing schedule 40 piping, pre‑fabricated manifolds, quick‑connect hoses, and daisy‑chained electrical supervision—reducing installation time and overall cost.
Designed for occupied spaces, IG‑55 maintains oxygen levels within safe limits for humans while rapidly discharging upon fire detection. With zero ozone depletion and zero global warming potential, it meets UL, FM, LPCB, NFPA, and ISO standards .
