Combustion Air Supply

Controlled intake air conditions for engine testing. Simulate positive, negative or no load on the air inlet of an engine.  Provide independent make up air for vehicle start-up and dynamometer testing.  Quantify airflow sensor performance.  Water or air cooled mechanicals.  Unitized construction.  Simplified installation, just connect utilities and operate.  Responsive after sales support through dedicated customer service and regional field service network.


  • Automatic modulation of pressure to control the load on the engine intake.
  • Single or multi-point feed to engine test cells.  Point source control of supply feed temperature and humidity by means of individual trim units downstream of main feed.
  • Conditioning packages that include single stage refrigeration and electric heat.
  • Can be integrated with existing software and HMI for remote set-point control and monitoring
  • Standard and custom designed systems available
  • 600 cfm to 50,000 cfm +
  • -40 F to 180 F +
  • Precise data acquisition of all required data
  • Data collection and computation through PLC based touch screen, also available through LabVIEW® automation software packages
