Inerting Control Systems

Incidents involving flammable materials claim lives, damage equipment, halt production, and cost companies millions of dollars each year. Ntron Process Inerting Control Systems can help manufacturers avoid these losses by controlling inert gas usage.

The Neutronics ICS controls Oxygen on the basis of a real-time measurement, making it the only direct-measurement method available for preventing process flash fires and explosions.

By continuously measuring oxygen levels and adding inert gas to the process only when necessary, Ntron ICS increases safety margins while reducing waste venting of Nitrogen and solvents. The savings can be significant. Ntron ICS uses up to 60% less inert gas than continuous flow, timed-volume, and pressurization inerting techniques.

Often when a chemical process is purged with inert gas, large amounts of VOCs are vented, which drives up the cost of scrubbing or incinerating the waste gas, as required by the EPA. By purging as needed only, the Ntron ICS reduces VOC emissions. Ntron offers complete stand-alone and transmitter-based systems for controlling inert gas purging.

ICS System Components

Three basic components are included in every Ntron Inerting Control System: The Sensor, The Sampler, and the Analyser.


The effectiveness of the ICS system depends on the reliability of the sensors. For over 25 years, Ntron Oxygen sensor technology has proven itself in demanding chemical processing applications. Tens of thousands of Ntron zero-maintenance, disposable electrochemical sensors are in operation today in plants around the world.


The key to reliable process gas monitoring is having a sample free of contaminates that can destroy your sensor. Ntron Inert Gas Control Systems utilize proprietary Process Sample Conditioning Packages to ensure that Gas Analysis results remain consistently correct over long operation intervals.


Ntron Inert Gas Control Analyzers automatically control Oxygen in the process environment to enable safe, consistent manufacturing operations. Ntron Analyzers advanced features such as system diagnostics and custom displays make the Inert Gas Control System the most useful and effective measure available for process flash-fire and explosion prevention
