Air Conditioning System

Test engineers face special problems during the first stages of the development of a new supercharged engine. Either a matching turbocharger is not available in time or the charge air con­ditions have to be varied over a wide range, independent of the engine’s operating point, the ambient pressure or test cell temperature.

The variable boosting system STS ChargeCon solves these problems. It provides the required levels of com­bustion air pressure and temperature. It maintains these levels over a wide range within narrow limits. The control and regulation of the system is performed by an on-board controller mounted in the control cabinet.



  • Stable experimental conditions reduce test cell time
  • Wheel base enables flexible use at different test cells
  • Simple operation
  • Low maintenance
  • Wide range of application
