TESTING

Pankl Turbosystems offers an extensive range of testing services in the area of exhaust gas turbocharging. Our offer extends from customized individual tests up to complete validation programs for our customers.

We are equipped with two modern hot gas test stands, a burst and containment test stand, and two engine test stands. Additionally, we have a comprehensive spectrum of special equipment for our hot gas test stands, such as a closed compressor circuit (closed loop system) for advanced turbine map measurement or a battery simulator for electrically assisted turbochargers, which permits such systems to be driven electrically or to dissipate recuperated energy.

  • Thermodynamic measurements (compressor and turbine mapping)
  • Functional testing of electrically assisted charging systems
  • Automated endurance testing according to provided load cycles
  • Rotordynamic and shaft motion measurements
