Air Separations Units (ASU)

Air Separation Units (ASU) refine air in a separation process with low distillation temperature (-196°C) allowing the bulk production of oxygen, nitrogen and argon. Air separation is also the most practical source for production of rare noble gases such as neon, krypton and xenon. Cryostar provides a wide range of high reliability cryogenic expanders and process pumps suitable for continuous duty applications.
