Kampaniyo imapereka zida zingapo zolekanitsidwa ndi mpweya zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana ngati metaldurgy, petrochemical, ndi astospace. Sinthani njira ndi zinthu zapamwamba kwambiri.
Mayunitsi olekanitsa mpweya (Asus) ndi gawo lofunikira kwambiri m'mafakitale ambiri ndikuchita zofunikira pakupanga njira zomwe zimafunikira mipweya yoyera. Amagwiritsidwa ntchito kupatula zigawo za mpweya ngati mpweya, nayitrogeni, argon, helium ndi mipweya ina yabwino. ASU imagwira ntchito pa mfundo ya firiji ya crybogenic, yomwe imagwiritsa ntchito mwayi wosiyanasiyana wa mpweya woyenera kudzipatula.
