-90℃~+200℃ High- and Low-Temperature Liquid Bath Circulation Unit TH-135-20RC
-90℃~+200℃ high- and low-temperature liquid-bath circulation unit. To test spacecraft components' ability to withstand the thermal-vacuum environment encountered in orbit and assess their performance, ground laboratories simulate high-vacuum conditions (10 Pa ~10 Pa) and test the components. This is known as component thermal-vacuum testing. The test equipment mainly consists of a vacuum vessel, test platform, refrigeration and heating systems, vacuum system, and measurement and control systems. With the rapid development of the aerospace industry and increasing requirements for spacecraft reliability and service life, thermal-vacuum test equipment has become indispensable. A common approach uses liquid-nitrogen wall panels with black-painted inner surfaces to simulate the cold, dark space environment. This simulation device is commonly called a heat sink. In general, its temperature differs from the sample temperature by at least 30℃. The company specializes in refrigeration, heating and circulating temperature-control systems for thermal-vacuum test platforms. The main equipment temperature ranges are -90℃~+150℃ and -140℃~+150℃.
