We’re Exhibiting at Space Tech Europe 2025

Space Tech Expo Europe, 18-20th November 2025, Bremen, Germany, Stand G56

Renewables

We have designed various sensors and components for some of the largest renewable energy companies around as well as also helped with small startup companies investigating Wind, Wave and Tidal renewable projects. Whether you need a sensor to monitor hydraulic spikes or a braking resistor to help with turbine dumped energy, we are here to help.
