Application requirements

Within Nefit Bosch's fundamental combustion research program, precise control over input variables is paramount. As insights from the experimental setup inform appliance development, the team at Nefit Bosch requires the ability to conduct experiments across a broad range of conditions while maintaining a high degree of accuracy to effectively map parameter planes.

Process solution

Bronkhorst supports this with the FLEXI-FLOW—a compact, multi-parameter mass flow controller with a full-scale range of 0–500 ln/min. Its integrated pressure and temperature sensors provide real-time insight into process conditions, while its modular design allows for quick reconfiguration of test setups. This flexibility enables Nefit Bosch to cater to their process requirements by supplying either hydrogen or conventional hydrocarbons and air to achieve accurately defined combustible mixtures.

In the applications of Nefit Bosch, the total volume administered and the instantaneous flow rate under varying temperature conditions are critical parameters. The new FLEXI-FLOW controllers address these needs exceptionally well. As the team at Nefit Bosch expands their extensive hydrocarbon combustion knowledge to hydrogen, the mass flow controllers' ability to easily accommodate different gases enables direct comparisons between these fuel types. Furthermore, the experiments often progress from steady-state conditions to continuous flow, approaching real-world appliance operation conditions. This demands high accuracy at both low and high flow rate extremes, a capability inherent in the unique Through Chip Sensor integrated in the FLEXI-FLOW Compact series.

What the customer says:

Tim Durinck, R&D Engineer:
"Thanks to Bronkhorst’s deep expertise in low-flow hydrogen applications, we don’t have to reinvent the wheel. Their FLEXI-FLOW technology gives us the precision and flexibility we need, so we can focus on what really matters: developing safe and efficient hydrogen heating systems."

Daniel Vernhout, R&D Engineer:
"With Bronkhorst instrumentation, Nefit Bosch can conduct precise testing and accelerate innovation."
