The DHT® Thermal Vacuum Test Chamber is specifically engineered for full lifecycle verification of spacecraft, precisely simulating the extreme environmental conditions of outer space. With a vacuum level reaching ≤5×10⁻⁶ Pa, a broad temperature range from –196°C to +180°C, and adjustable solar radiation intensity between 1120 and 1500 W/m², it enables comprehensive environmental reliability testing in accordance with ECSS-E-ST-10-03C, MIL-STD-1540E, and GJB 1027A-2021 standards.
This system has been successfully deployed in key aerospace applications, including thermal deformation testing of phased-array antennas on low-Earth orbit satellites, thermal management validation of isotope power systems for deep space probes, and integrated thermal-vacuum trials of reusable commercial launch vehicles. It provides critical data for in-orbit failure analysis, accelerated lifespan assessment, and evaluation of spacecraft adaptability to space environments.
