Used NTRON a Neutronics Company Inerting Control System (ICS) Cart System and Oxygen Analyzer System, Explosion Proof. The ICS is a closed loop system that continuously measures oxygen, adding inert gas only when necessary to maintain a safe, inert atmosphere. The ICS can save up to 60% in inert gas usage and result in less emissions (Volatile Organic Compounds - VOC's) that need to be vented, scrubbed or incinerated. The NTRON ICS cart consists of two subassemblies: The ICS Analyzer and the Sample Conditioning Package mounted together on a wheeled cart. Together they make the only complete Inerting Control System for controlling oxygen levels in process environments.
