What is an Air Separation Unit (ASU)
Beds automatically switch every 5-8 hours. The air from the PPU is very close to moisture and CO2 free. Some older ASUs utilize reversing heat exchangers to accomplish front end clean up. These systems contain special cryogenic heat exchangers that freeze out the moisture and CO2, allowing clean air to flow to the distillation process.
