Location & approach

By Car

The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dortmund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dortmund-Dorstfeld" (closer to Campus Nord). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.

To get from Campus Nord to Campus Süd by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus Nord and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.

By train

TU Dortmund University has its own train station ("Dortmund Universität"). From there, suburban trains (S-Bahn) leave for Dortmund main station ("Dortmund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.

You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop "Dortmund Kampstraße". From there, take U43 or U44 to the stop "Dortmund Wittener Straße". Switch to bus line 447 and get off at "Dortmund Universität S".

The H-Bahn (Suspended Monorail System)

The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on Campus Nord. One ("Dortmund Universität S") is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.

Making Better Use of Industrial Waste Heat

07/21/2026

Eine Hand hält einen Globus vor dem Hintergrund einer grünen Wiese mit blauem Himmel.

Process heat alone accounts for about two-thirds of the German industrial sector’s final energy demand. At the same time, a large portion of the waste heat generated in industrial processes is still lost to the environment. A new invention from TU Dortmund University is helping to minimize such energy losses: Prof. Andreas Brümmer, together with his team from the Fluid Technology Department at TU Dortmund University (department of Mechanical Engineering), has developed an optimized screw-spindle expander, which has now been sold to the company Cixten with the support of the CET.

Specifically, it involves a combination of a screw-spindle expander—which converts thermal energy from waste heat into mechanical energy during gas expansion—and a screw-spindle compressor, which uses that mechanical energy directly to compress a gas. Thanks to the special design of the screw-spindle expander, with counter-rotating rotors, the resulting bearing forces remain well under control even under significant pressure differentials. This ensures wear-free and energy-efficient operation, for example, when used in large heat pumps.

Increasing Sustainability in Industry

Together with the Research Legal Affairs Department within the Finance and Procurement Division and PROvendis GmbH, the CET supports and guides inventors from the initial idea through the patenting process to the successful commercialization of their invention and the conclusion of corresponding contracts. As a result, the rights to the patented invention have now been sold to the French company Cixten. The company specializes in the recovery and conversion of low-temperature waste heat into usable energy. “For us, this development stemming from scientific research is another important building block for improving our technologies and increasing energy efficiency and sustainability in industry,” explains Philippe Wagner, CTO and founder of Cixten.
