SF6-alternative gases Vacuum Charging separating unit

An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.. The most common method for air separation is fractional distillation.Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.
