Kala-soocida dabaylaha duufaantu waa qalab gaas adag oo kala-saarid ah. Waxay isticmaashaa mabda'a duufaanta si ay u kala saarto adkaha adag, oo ay ku jiraan wasakhda, qashinka dhagaxa, jajabyada birta, miisaanka, iyo kiristaalo alaabta, laga bilaabo gaaska dabiiciga ah ee leh condensate & biyaha (dareereyaal, gaas, ama gaas- dareere ah). Marka lagu daro tignoolajiyada gaarka ah ee SJPEE, oo leh noocyo taxane ah oo liner ah (, element filter), kaas oo ka samaysan tignoolajiyada sare ee xirashada u adkaysta (ama loo yaqaan aadka ka-hortagga nabaad-guurka) ama walxaha polymer-ka-adkeysiga u leh ama walxaha birta ah. Qalabyada kala-soocidda adag ee waxtarka sare leh ayaa loo qaabayn karaa oo la soo saari karaa iyadoo loo eegayo xaaladaha shaqo ee kala duwan, beeraha kala duwan iyo shuruudaha isticmaalaha. Iyada oo la rakibay cutubka duufaanta, dhuumaha hoose ee badda hoosteeda ayaa laga ilaaliyay nabaadguurka iyo adkaha inay dejiyaan waxayna aad u yareeyeen inta jeer ee hawlgallada doofaarka.
