Test Procedures
Ensure installation space allows safe operation and access to all test channels.
Connect the system to the 60 kW power supply and ensure environmental temperature control is set.
Fill the system with glycol/water test medium.
Install the radiator, hose, or expansion tank in the test chamber.
Close front and rear doors to seal the chamber.
Set the desired pressure range, linear motion parameters, and temperature profiles in the control unit.
Start the test program via Windows/LabVIEW interface.
Monitor pressure, motion, temperature, and leak sensors throughout the test.
Automatically shut down any failed or leaking samples.
After testing, safely drain the test medium and allow the chamber to cool before removing samples.
Maintenance Information
Regularly inspect the motion drive, pressure sensors, and leak detection units for wear or damage.
Check glycol/water circulation system for blockages or leaks before each test.
Calibrate sensors and temperature controllers periodically to maintain measurement accuracy.
Clean environmental chamber surfaces and doors to prevent corrosion.
Replace worn seals, gaskets, or insulation as necessary to ensure safe operation.
