INERT GAS

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
