Kampaniyo imapereka zida zosiyanasiyana zolekanitsa mpweya zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana monga zitsulo, petrochemical, ndi ndege. Sinthani njira zogwirira ntchito ndi zinthu zathu zapamwamba.
Ma Unit Olekanitsa Mpweya (ASU) ndi gawo lofunika kwambiri m'mafakitale ambiri ndipo amachita gawo lofunikira popanga zinthu zomwe zimafuna mpweya woyera. Amagwiritsidwa ntchito kulekanitsa zigawo za mpweya monga mpweya, nayitrogeni, argon, helium ndi mpweya wina wabwino. ASU imagwira ntchito motsatira mfundo ya cryogenic refrigeration, yomwe imagwiritsa ntchito malo osiyanasiyana owira a mpweya uwu kuti iwalekanitse bwino.
