The TVC - Space Simulator 700L by Weiss-Technik is a Thermal Vacuum Chamber with a pressure vacuum capability of 10^-6 mbar and an operating temperature range of -50 to 100 deg C. This chamber has a power dissipation of 200 W and boasts a rapid cooling rate of 3 degrees C/min. It comprises a cylindrical vacuum chamber equipped with independently regulated thermal plates and shrouds, machinery, and pump-installed frame, an electrical cabinet with a control panel, and a supervision and control system known as SPIRALE Vs. The vacuum chamber has a test space volume of 780 x 1000 mm and measures 2500 x 3840 x 1800 mm. It is ideal for performing thermal cycling tests under secondary vacuum conditions on electronic components for space applications.
