Vacuum degassing equipment for space probes

This device can meet the degassing process requirements for space detectors and effectively shorten the cooling time. The entire system uses a low-temperature pump as the main pump, with a dry pump serving as the pre-pump for the low-temperature pump and for pre-evacuating the container, to achieve a clean, oil-free vacuum degassing environment. In terms of temperature control, an advanced PID temperature controller is used, providing high precision in temperature control. Additionally, filling the vacuum chamber with nitrogen allows the workpiece to quickly return to room temperature from a high vacuum state. This equipment features high vacuum levels, easy and uniform temperature control, long-term stable and reliable operation, and simple operation. It can be used for vacuum degassing tests of various aerospace product components.
