Cooling circuit development from a single source
Thermally safe. Efficiently designed.
Modern drive concepts, downsizing and electrification place high demands on cooling circuits. We develop and validate systems that ensure thermal stability, minimize energy losses and ensure maximum service life - from the initial idea to series release.
From the digital model to the practical test
Holistic development for every drive concept
PTS-Prüftechnik combines simulation, test bench testing and vehicle testing to create an end-to-end development process. We focus on your technical framework conditions and project goals - and adapt our tests to your drive strategies: flexibly, practically and in partnership. This saves you time and gives you reliable results - precisely tailored to your requirements.
