I.Usetyenziso:
Isixhobo sokuvavanya uxinzelelo lwendalo sisetyenziselwa kakhulu ukufumana i-phenomenon yokuqhekeka kunye nokutshatyalaliswa kwezinto ezingezona zetsimbi ezifana neeplastiki kunye ne-rubber phantsi kwesenzo sexesha elide loxinzelelo phantsi kwesivuno sayo. Ikhono lezinto zokumelana nomonakalo wokuxinzezeleka kokusingqongileyo kulinganiswa. Le mveliso isetyenziswa ngokubanzi kwiiplastiki, irabha kunye nezinye imveliso yepolymer izinto, uphando, uvavanyo kunye namanye amashishini. Ibhafu ye-thermostatic yale mveliso ingasetyenziswa njengesixhobo sokuvavanya esizimeleyo ukulungisa imeko okanye ubushushu beesampuli ezahlukeneyo zovavanyo.
