TOPAQ High Pressure Regulation Unit
- The High Pressure Regulation Unit (HPRU) is used to ensure safe and robust hydrogen feed to the low pressure line of fuel cells or internal combustion engines (PFI and DI) of stationary and mobile deployed H2 applications.
- Designed for CGH2 applications with system pressures of 350 and 700 bar, its active pressure control enables the free adjustment of the outlet pressure during operation in a pressure range of 0 – 75 bar.
- Functionality
- The outlet pressure is changed via the system's Electronic Control Unit (ECU) and can be implemented without any mechanical changes to the pressure regulator, thus realizing a load-dependent outlet pressure.
- The active pressure control enables inlet pressure fluctuations and dynamic load fluctuations of the consumer under varying temperatures to be compensated and a very high control quality to be maintained, while simultaneously providing the possibility to regulate the system in advance for faster response times.
- Design
- With its optimized modular design, it enables the compliance of individual customer requirements with the possibility to use different sensor options, optimized regarding pressure range and signal processing.
- For installing the HPRU, only an installation space of approx. 260 mm × 191 mm × 82 mm is required.
Key features
