This equipment can meet the requirements of degassing process for space detector, and can effectively shorten the cooling time. The whole set of equipment adopts low-temperature pump as the main pump, dry pump as the front stage of low-temperature pump and container pre pumping, so as to obtain a clean and oil-free vacuum degassing environment; in terms of temperature control, the advanced PID temperature controller is used to control the temperature, with high temperature control accuracy. In addition, the vacuum chamber filled with nitrogen can make the workpiece rapidly drop to room temperature in high temperature vacuum state. The equipment has the advantages of high vacuum, easy temperature control, good uniformity, stable and reliable long-term operation and simple operation. It can be used in vacuum degassing test of various aerospace products.
