Application principle of cold trap (-45°C~-135°C):

There are certain residual gases in the high vacuum environment using oil diffusion pumps, more than 80% are water vapor, oil vapor and other high boiling point steam, but its ability to extract residual gases is low, long time, and the residual gas is also a source of pollution of the workpiece, so that the output and quality of the product are affected, ultra-low temperature capture pump is the best choice to solve the problem.

There are certain residual gases in the high vacuum environment using oil diffusion pumps, more than 80% are water vapor, oil vapor and other high boiling point steam, but its ability to extract residual gas is low, the time is long, and the working principle of the residual water vapor capture pump: a refrigeration coil that can reach below -130 °C is placed in the vacuum chamber or the pump port of the oil diffusion pump, and the residual gas of the vacuum system is quickly captured through the low-temperature condensation effect on its surface. As a result, the evacuation time can be greatly shortened (60-90% of the pumping time can be shortened) and a clean vacuum environment is obtained (the vacuum degree can be increased by half an order of magnitude, reaching 10-8Torr, 10ˉ5Pa).
