ETC’s Conditioned Air Supply (CAS) system provides air at precisely controlled temperature, humidity, pressure and flow rate conditions to perform a variety of combustion engine research and development, fuel cell and emissions applications.

ETC’s specialized pressure control valves utilize high performance actuators to accurately control the intake pressure at the engine steady state and throughout engine test profiles. The adverse effects from variations in environmental conditions are completely eliminated with the CAS System to provide the highest degree of accuracy, allowing test programs to be more efficient. It also allows precise re-creation of previous test conditions for comparison purposes.

In keeping with the current green initiative, the Conditioned Air Supply (CAS) utilizes environmentally safe refrigerants and reduces energy consumption.
