Class 8 Test Chamber

Ideal for large truck, extended bus, harvester, recreational vehicle and military vehicles.  Quantify long term effects of extended operation under cold soak conditions.  Perform vehicle “defrost” and “climate control” testing.  Perform “body” or “exterior” test studies at varying temperature ranges.  Include the supplemental integration of an infrared or full solar simulator tp qualify effects of long term sun & radiant heat exposure.


  • -40F dry air combustion system assures long term performance of chamber cooling coil.
  • Optional solar array packages available with multiple zone control and vertical/side mounted profile.
  • Direct expansion refrigeration system standard, options available for secondary “brine” conditioning for added control capabilities.
  • Chamber can be integrated with external testing equipment including servo actuated road simulation.
  • Optional sound attenuation packages availablefor hemi-anechoic testing.
  • Integrated “Snow” generation and “Windshield” spray systems options available
  • Data collection and computation through PLC based touch screen.  Also available through LabVIEW® automation software packages.
