Features
- The smallest gas volume in the system
- The smallest pressure can be detected to prevent air from entering
- Fail-safe standard communication protocol
- Continuous hydrogen leak detection
- Fail-safe logic control
- Uninterruptible power supply to ensure safe shutdown in the event of a power failure
- Continuously monitor the purity of oxygen products
- Multi-layer control system
- Multiple redundant protection of key safety parameters
- Pressure control: The operator can select the appropriate gas pressure (8-10 bar) through the HMI (Human Machine Interface) on the control panel to automatically adjust the production rate to maintain the set pressure.
- Automatic cooling: The flow of cooling water into the heat exchanger is controlled by a controlled flow regulating valve. When the temperature rises, the flow rate is automatically increased to ensure a stable hydrogen production temperature.
- Set energy consumption: In order to integrate the volatility of power resources, the maximum output of hydrogen can be produced under limited conditions according to the set power, while ensuring the normal operation of other public facilities.
- Fully automatic nitrogen purge: The control system will program to control different valve operations to complete the nitrogen purge. Ensure that all air in the system is exhausted before hydrogen production.
- Remote I/O: The most advanced profibus connection system is adopted. Based on this technology, we have greatly reduced the field cable connection. The control system is more safe and reliable and meets the most stringent safety standards and regulations. The control system will automatically analyze and diagnose any communication faults, which not only improves the safety of the system, but also reduces the time for fault analysis, search and maintenance.
