Rotary piston pump
So far, the problem of sealing has been a major challenge when using rotary piston pumps.
Vibration Reduction
The device is particularly advantageous for the transportation and assembly of wind turbines. Vortex-induced vibrations are significantly reduced or avoided. In principle, the device can be used for all cylindrical structures (e.g. pillars) that need to be protected from vortex-induced vibrations.
Seal effectiveness doubled
The sealing concept consists of two independent seals. This provides additional safety. The gaskets are particularly suitable for plastic flanges. Only low forces are required and leakages are avoided. Extensive measurements have already been carried out.
Optimized radial compressor
Moving blades can be used in compressors, superchargers and exhaust gas turbochargers to increase overall efficiency by extending the operating range. This new technology was developed at the University of Duisburg-Essen and can be used across all industries.
Efficient fuel cells
The efficiency in fuel cells can be increased by using the waste heat of the fuel cell and the pressure energy of the hydrogen tanks. A system module consisting of a turbine with generator and a heat exchanger can significantly increase the overall efficiency of the process in the fuel cell.
Hydrophobic Phytic Acid Conversion
The innovation presented here concerns the production and use of hydrophobic phytic acid derivatives as an environmentally friendly alternative to conventional phosphate corrosion protection pre-treatments for steel.
