Test bench designed for heat exchanger testing:
• Efficiency;
• Dp of mass flow;
• DT.
The system consists of 4 circuits (primary air, secondary air, water / glycol mixture, oil), all controlled in flow, pressure and temperature to simulate and test radiators operating conditions (cars, heavy vehicles, agricultural machinery, special applications). All operations are controlled by the control console, which also includes the DAS (data acquisition system) and test report recording.
