Model Number: Water vapor cryopump ASH-135
Key Specifications/Special Features:
Why is cryogenic entrapment pump capable of increasing the evacuation rate of a high vacuum device and elevating the vacuum degree?A cryogenic coil at ultra-low temperature is placed in the vacuum chamber or at the oil diffusion pump inlet. Water vapor and other gases in the vacuum system can be rapidly condensed on the cryogenic coil according to the low-temperature condensation effect of glass; accordingly. The air pressure in the vacuum chamber can be reduced. The time for vacuum evacuation can be significantly reduced. And the vacuum degree can be elevated by half or one order of magnitude, as a result, the production efficiency can be greatly improved and the production cost cut down. Therefore, this product is known as a good helper in the vacuum industry and energy saving pioneer of vacuum coating systems.Beijing Tiandijingyi Technology Co. LTD entrapment pumps by using the state-of-the art single-unit auto-cascade refrigeration system. Selecting compressors and refrigeration parts of globally famous brands.ang adopting new environment-friendly mixed refrigerants. Through technological improvement the performances of cryogenic entrapment pumps produced by our company is bettered and stabilized. These pumps feature high refrigeration speed. Low refrigerating temperature, no greasy blockage. Wider range of cooling water temperature, simple installation and operation. All indictors of which have reached the international advanced level.
