Pressure Cycle Testing Cooling Circuits with Under- and Overload Pressure
A state-of-the-art pressure pulsation test stands with media flow control and pressures up to 12 bar. The pressure pulsation rig is a flexible system and can be adapted to customers’ testing requirements. It covers tests for industry standards such as VW8000 or BMW Group M07 with under and overload pressure, which is currently a highly requested test for electronic vehicle components. A pressure test rig is an independent unit. It contains a media temperature control unit and an integration into a climate chamber. The pressure rig is powered by up to 12 bar by a hydraulic pressure intensifier. It has the capability to perform a vacuum test with a pressure change from negative pressure to positive pressure.
Typical DUTs are electronic control units (ECUs), cooling systems, liquid-cooled power converters, battery housing, and many more.
