Solar simulation chamber

Positionieren einer Superisolationsmatte (MLI) auf dem Testobjekt

The solar simulation chamber serves for thermal vacuum testing of both individual components and overall systems for space applications. The environmental conditions that will be encountered in space, such as high vacuum, the cold temperature in space and solar radiation, can all be recreated during these simulations. Where necessary, the temperature-controlled wall (shroud) can be cooled with liquid nitrogen.

The aim of the thermal vacuum test is to support the process of designing space components and thermal control systems, their qualification and the verification of numerical thermal models.

The solar simulation chamber is accredited as a testing laboratory in accordance with DIN EN ISO/IEC 17025:2005 and fulfils the clean room requirements of ISO-8 in accordance with Standard ISO 14644-1.

Service range

For thermal balance tests – thermal vacuum tests, the main area of interest is thermal balance and the respective temperature distribution
In thermal cycling tests – the functionality of the test object is examined using a predetermined number of cycles under certain temperatures (environmental conditions).
