Add to compare

The Back Pressure System is designed for accurate, independent control and measurement of anode and cathode pressure. It is constructed entirely of stainless steel, including regulators, condensate collection tanks, tubing, and fittings. The system features a dual channel with isolated flow paths and is suitable for use with gas having a dew point up to 120°C at 10 SLM. It offers precise pressure control with an accuracy of ±3.5 kPa or 0.5 psi, ensuring stability across a flow rate range of 0.1 to 12 SLM. The system supports flexible pressure control through FuelCell® and includes options for High Temperature, Standard, and Automatic Back Pressure systems. It also provides maximum back pressure set points, alarm triggers, and the ability to program pressure profiles using Change Pressure Experiment or Arbitrary Control Experiment. The system ensures accurate pressure control and stability, making it ideal for applications requiring precise and independent pressure management.

Use Cases
