Gas Mixing, Delivery & Purge

Fideris gas mixing and gas blending modules automatically blend precise mixtures

Standard Features:

  • Mix and Match modules to deliver various flow rates and gases. Liquid delivery modules are also available
  • Use multiple gas mixing modules to create precicely controlled custom gas blends in real time
  • Mass flow control of flow rates up to 2500 SLPM per gas; combine multiple modules for expanded gas blending and mixing capabilities
  • All-digital control eliminates analog calibration requirements and inaccuracies
  • Ethernet Interface for simple configuration and expansion!
  • The output from multiple Gas Delivery Modules may be combined to provide dynamically controlled gas flow rates and compositions, including Stoichiometric control
  • System-wide control of all Fideris Test System components using FCPower Software, LabviewTM, or other programming language 
  • Integrated hardwired Run/Standby signal
  • Power Over Ethernet (PoE) for redundant power
  • Front panel LED status of Ethernet communications, inlet gas pressure, gas enabled, and power
  • Check valves for gas backflow prevention
  • Pressure regulator on inlet gas line to provide the highest degree of accuracy 

Typical Applications

  • Fuel Cell Testing
  • Simulated reformate blending
  • Controlled atmosphere composition control
  • Calibration gas generation
  • Gas Blending
  • Sensor Testing
  • Environmental Chamber atmosphere control
  • Catalyst Testing and Evaluation
