Testing aerospace equipment before the first flight into space is a requirement in order to be able to predict the behaviour of these valuable components. They are tested by simulating space conditions. The weisstechnik^® temperature vacuum cabinets accurately reproduce space conditions and make it possible to conduct such a test in a completely controlled environment. Our high-performance pump systems can reach a vacuum of up to 10^-7 mbar. Liquid nitrogen, which circulates in the temperature vacuum cabinet produces temperatures from -185 °C to +165 °C. Features, such as infrared radiation or a spacial temperature gradient, can be simulated according to the customer’s requirements.
