An air separation unit (ASU) is a piece of equipment used to separate air into its primary components, including nitrogen, oxygen, and argon. This process is achieved through a series of steps, including compression, cooling, and expansion. The resulting gases are then used for various applications, such as in the production of chemicals, pharmaceuticals, and electronics. ASUs are critical pieces of equipment in many industries and choosing the right supplier is crucial to ensure the unit meets your specific needs and operates efficiently.
