Environmental Test Chamber - Thermal Vacuum Test Chamber

Thermal Vacuum Test Chamber

The Thermal Vacuum Test Chamber is utilized for military and aerospace applications to replicate space vacuum conditions, cold black, and solar radiation environments within terrestrial settings. This equipment conducts thermal vacuum tests and thermal balance tests.

The ground simulation test equipment for space environments can emulate the cold and hot conditions of vacuum space. It performs thermal vacuum testing on test specimens while effectively controlling, monitoring, and recording the temperature within the vacuum environment. These capabilities provide essential conditions for researching related aerospace products.
