Inert Gas Control System (ICS)

Mini ICS

Percent O2 analyzer / controller

For Inert Gas Concentration Control

The Mini-ICS (Inert Gas Control System) is a compact series analyzer designed for continuous real-time oxygen monitoring and concentration control of nitrogen or inert gases.  When combined with a properly designed sample conditioning package, the Mini-ICS provides reliable measurement of oxygen levels and automatically maintains oxygen levels within specified limits by controlling the flow of inert gas into the process.

Inert gas blanketing protects plant personnel, products, and plant assets by reducing the oxygen content in the vapor space of a tank or process vessel.  Making the vapor space inert eliminates the possibility of fire or explosion, decreases evaporation, and protects the vessel from structural corrosion damage.  Blanketing also prevents air, moisture, or other contaminants from entering the vapor space and causing product quality degradation.
