DESCRIPTION
INERGEN agent is a plentiful, non-corrosive gas that does not support
combustion nor react with most substances. INERGEN agent contains
only naturally-occurring gases which have no impact on the ozone or
the environment in general. INERGEN agent is a mixture of three inert-
ing (oxygen diluting) gases: 52% nitrogen, 40% argon, and 8% carbon
dioxide. INERGEN agent extinguishes fire by lowering the oxygen
content below the level that supports combustion. When INERGEN
agent is discharged into a room, it introduces the proper mixture of
gases that still allow a person to breathe in a reduced oxygen atmo-
sphere. It actually enhances the body’s ability to assimilate oxygen.
The normal atmosphere in a room contains approximately 21% oxygen
and less than 1% carbon dioxide. If the oxygen content is reduced
below 15%, most ordinary combustibles will not burn. INERGEN
agent will reduce the oxygen content to approximately 12.5% while
increasing the carbon dioxide content to about 3%. The increase in
the carbon dioxide content increases a person’s respiration rate and
the body’s ability to absorb oxygen. Simply stated, the human body is
stimulated by the carbon dioxide to breathe more deeply and rapidly to
compensate for the lower oxygen content of the atmosphere.
PERFORMANCE
INERGEN agent is an effective fire extinguishing agent that can be
used on many types of fires. The INERGEN fire suppression system is
designed for total flooding protection against Class A surface burning,
Class B flammable liquid, and Class C fires occurring within an enclo-
sure by lowering the oxygen content below the level that supports
combustion.
INERGEN agent has been tested by FM Approvals for inerting capabil-
ities. Those tests have shown that INERGEN agent, at design concen-
trations between 40% and 50%, has successfully inerted mixtures of
propane/air, and methane/air.

Cylinder assembly options include the INERGEN 150 Bar and 200 Bar fire suppression systems.

INERGEN 150 Bar—The cylinder assembly is of steel construction with a red standard finish. Four sizes are available to meet specific needs. Each has a pressure seat-type valve equipped with a gauge. The valve is constructed of forged brass and is attached to the cylinder, providing a leak-tight seal. The valve also includes a safety pressure relief device that provides relief at 2900-3300 psi (200-228 bar) per CGA test method. The cylinder charging pressure is 2175 psi at 70 °F (150 bar at 21 °C).

INERGEN 200 Bar—The cylinder assembly is of steel construc­tion with a red standard finish. One size is available. Each cylinder has a pressure seat-type valve equipped with a gauge. The valve is constructed of forged brass and is attached to the cylinder providing a leak-tight seal. The valve also includes a safety pressure relief device that provides relief at 4000-4480 psi (276-309 bar) per CGA test method. The cylinder charging pressure is 2900 psi at 70 °F (200 bar at 21 °C).

FEATURES

INERGEN extinguishing agent used in ANSUL engineered systems
is particularly useful for hazards where an electrical, non-
conductive
medium is essential or desirable; where clean-up of other agents
presents a problem; where hazard obstructions require the use of a
gaseous agent; or where the hazard is normally occupied and requires
a non-toxic agent.
The following are typical hazards protected by INERGEN systems:
- Computer rooms
- Subfloors
- Tape storage
- Telecommunications/Switchgear
- Vaults
- Process equipment
- All normally occupied or unoccupied areas where electronic equipment is either very sensit
   sensitive or irreplaceable
