Range of Applications for Vacuum Engineering is Growing Constantly for vacuum pumps

Posted on Fri, 18 May 2018 10:09:00 +0000

Vacuums are used in industry and commerce for packaging, drying, suction and pick-and-place. Some process engineering operations are carried out in a vacuum because low pressure is an advantage on temperature-sensitive products. And in a vacuum column, it is even possible to split azeotropic mixe...
