EC 9500 Nitrosave Oxygen Control System, chemical cell

 

 

 

 

 

 

 

 

 

 

 

Nitrosave consists of the oxygen monitor/control unit and a proportional or other control valve which is fitted into the nitrogen supply line to the machine.

Nitrosave monitors the residual oxygen in the system under control using our latest cell technology. The oxygen measurement is then used together with a fuzzy logic control algorithm and user-defined set points for desired oxygen level, to automatically control the opening of the valve, which regulates the flow of nitrogen into the machine.

This ensures enough nitrogen to comfortably maintain the desired oxygen level is fed into the machine but eliminates the  waste seen with fixed-flow nitrogen systems.


Features & Benefits

  • Save on nitrogen usage and rework costs.
  • Improve process control and product quality.
  • Automatically detects a halt in production and reduces nitrogen flow for even greater savings.
  • Extremely fast response time even after high oxygen exursions means quicker process optimization.
  • Nitrosave Viewer PC software makes set up quick and easy.
  • USB and RS485 communications output for data logging can document the whole process.
  • Small footprint allows OEM manufacturers to install inside their machines.
  • Conforms to European Directives: Electromagnetic Compatibility Directive 2004/108/EC Low Voltage Directive 73/23/EEC
