INERT GAS
NAFFCOInert® fire
suppression system is an engineered system using with fixed nozzle agent and
pipe network. NAFFCOInert® systems are designed in accordance with
latest edition of NFPA 2001,”Standard on clean agent systems”. This system
shall be designed for Class A, Class B & Class C application, it extinguish
fire by reducing residual oxygen concentration to a level will no longer
support combustion. The system can actuate by detection and control equipment
for automatic operation along with providing local manual operation when
needed.
Basic Uses: NAFFCOInert®
fire suppression system is particularly useful for suppressing fires in hazard
areas where an electrically nonconductive medium is essential or desirable.
Where the clean environment and the hazard obstructions require the use of a
gaseous agent. It is an ideal replacement agent for Halon 1301 alternative.

PRESSURE
REGULATOR TECHNOLOGY
Pressure Regulators
modulate the discharge pressure to a constant 40-60 Bar which still delivers the
design concentration within 60 seconds, but with significant performance and
cost benefits:
BETTER
SAFETY
• Prevents discharge
freeze-up
• Prevents explosive force
of discharge
SAVES
TIME AND MONEY
• Enables low pressure
manifolds & pipework to be used that are of lower cost and easy to install
• Reduces the difficulty
and cost of locating/fitting pressure vents in the protected space
EASY
MAINTENANCE
• After a system discharge,
simply remove the regulator, recharge, and reconnect. No reconditioning
necessary
• Functional tests
are possible even while the SYSTEM IS ARMED
