The PTW currently has three test halls available for research activities. The original test hall of the PTW TEC-Lab accommodates modern machinery as well as a climate-stable measuring and trial machining room, the mechanical support and the training workshop. In 2007, the test field was expanded by the Process learning factory CiP (Centre for Industrial Productivity), with an area of 500 m², in which the principles of lean production are researched and presented in a tangible way. At the beginning of 2016, the energy efficiency, technology and application centre ETA-Factory was opened, a new factory building with 770 m². On the research side, especially topics of energy efficiency and energy flexibility are addressed here at the building and machine level.
