New pressure pulse testing rig for EV components from Poppe + Potthoff

November 19, 2023

Poppe + Potthoff Maschinenbau has introduced a new Pressure Rig for testing cooling circuit components, designed to meet industry standards such as VW8000 and BMW Group M07, and can handle pressures of up to 20 bar.

It’s used to test a variety of components including electronic control units (ECUs) and their cooling circuits, cooling plates, battery housings, AD/DC, DC/DC converters, high voltage cooling heaters (HVCH), heat exchangers, liquid-cooled power converters, and more.

The Pressure Rig is equipped with media flow control and can be customized to meet specific testing needs. It is designed to test cooling circuit components under various pressure conditions, responding to the increasing demand for such tests in the automotive industry.

The Pressure Pulsation Rig, an independent unit, features an integrated media temperature control system and a climate chamber. It is powered by a hydraulic pressure intensifier and can handle pressures up to 20 bar. This makes it suitable for pressure cycle testing and vacuum testing with a pressure change from negative to positive pressure.

Technical Specifications:

  • Pressure cycle test with flow control: 0.2 bar – 6 bar (rel.) at 30 1/min

  • Overpressure test (up to 4 bar for ~1 hour)

  • Vacuum testing for ~ 30 min

  • Pressure change from negative pressure to positive pressure under medium (without flow control): 0.5 bar – 2.5 bar

  • Includes a hydraulic system

  • PC with LabView-Software integration

  • Seamless connection to climate chamber

  • Test media: (Water-) Glycol (gas for vacuum testing)

  • CE-compliant

  • Compliant with GS 95024-3-1 M-07, MBN 10306 M-07, GMW141913, and VW80000 M-07 standards
