Thermal Vacuum Test System (TVAC) – QualiTVAC™ 1200 Series

The behavior of satellite components in high vacuum and extreme temperatures is confirmed through TVAC testing. For satellite-level single units (components) that need reliable vacuum performance and stable thermal control, QualiTVAC™ 1200 is designed. The system provides repeatable thermal cycling and performance verification by integrating a vacuum chamber, heat sink, and cold plate. Clean vacuum operation, regulated heat flow, and consistent temperature readings throughout test runs are design priorities.

A thermal vacuum (TVAC) test system for component-level space simulation is called QualiTVAC™ 1200. In order to assess functionality, thermal response, and durability, it generates a controlled low-pressure environment while cycling temperature across a broad range. Throughout test profiles, heat extraction and thermal stability are supported by a dedicated heat sink and cold plate. The size of the chamber allows for useful fixturing for instrument modules and satellite subsystems. In aerospace and advanced electronics labs, this setup facilitates qualification, acceptance, and investigative testing.
