Your innovative partner in test bench construction

System components for fuel cells

In the future, hydrogen will become an increasingly important medium in many areas – including test bench technology. To be prepared for tomorrow's challenges, rely on HYDAC as your partner for test benches designed for fuel cell components and hydrogen components. As a driver of innovation for many years, we impress with our media conditioning, flushing, process monitoring and much more.

System components for electrolysers

In an electrolyser, electrical energy is used to split water into its components – oxygen and hydrogen. HYDAC provides solutions for your electrolyser testing. We find the best custom solution for you when it comes to cooling and controlling the temperature of various media.

Electrical drives and gears

Electromobility is making a vital contribution to decarbonisation. Test bench technology ensures the functionality of these vehicles. That's why we focus on supporting your end-of-line test bench construction. Thanks to many years of expertise and a worldwide presence, HYDAC is your contact for the imminent questions surrounding test bench technology in the context of electromobility.
