IPEcomp R744

Validation test bench for EKMV and MKMV

IPEcomp R744

On the IPEcomp validation test bench for automotive refrigerant compressors, both electrically (eKMV) and mechanically (mKMV) driven DUTs can be subjected to performance and endurance tests. By mounting the test item on a mechanically decoupled, seismic mass, NVH tests on the test item are also possible.

  • Test von mechanischen und elektrischen Kompressoren
  • Simulation of operating conditions in the HVAC cycle
  • VDA complied mounting bracket with decoupled seismic mass
  • Manual and automated test operation
  • Inline measurements of oil curculation ratio (OCR)
  • Endurance tests, FAT (Factory Acceptance Tests), etc.
  • Supports NVH tests and gas pulsation measurements
  • Easy compressor exchange by automatic coolant evacuation
  • Intuitive test bench control via IPEmotion software
