VAPOR TRAPS |
摘要 |
In a refrigerated vapor trap for a vapor vacuum pump, the refrigerated trapping surfaces are arranged to be screened from external heat sources by additional water-cooled surfaces so that should the supply fail of the refrigerating liquid (such as liquid nitrogen) then the trapping surfaces reach a temperature which is still below ambient.
