Pressure Alteration Testing for Cooling Circuit Components

Discover the cutting-edge world of pressure pulsation testing with Poppe + Potthoff Maschinenbau’s state-of-the-art Pressure Rig! Equipped with media flow control and capable of handling pressures of up to 20 bar (and more), this flexible system can be customized to meet the unique testing needs of our valued customers.

Our Pressure Rig is specially designed to conduct tests adhering to industry standards such as VW8000 or BMW Group M07, which involve subjecting cooling circuit components to under and overload pressure conditions. Given the rising demand for such tests in the automotive industry, our rig stands ready to deliver precise and accurate results.

Pressure Pulsation Test with Water-Glycol Flow, Sinusoidal and Trapezoidal Pressure Curves in Climatic Chamber

As an independent unit, our Pressure Pulsation Rig boasts an integrated media temperature control system, seamlessly incorporated with a climate chamber. Powered by a hydraulic pressure intensifier, it can confidently handle pressures up to 20 bar, making it the ideal tool not only for pressure cycle testing but also for vacuum testing with a pressure change from negative to positive pressure.

At Poppe + Potthoff Maschinenbau, we frequently test various 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 other components under rigorous pressure cycling. Our rig ensures optimal performance and reliability under real-world conditions.

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
  • Inclusive of hydraulic system
  • PC with LabView-Software integration
  • Seamless connection to climate chamber
  • Test media: (Water-) Glycol (gas for vacuum testing)
  • CE-compliant
  • Flexibly designed to meet your requirements
  • Compliant with GS 95024-3-1 M-07, MBN 10306 M-07, GMW141913, and VW80000 M-07 standards
