Pulojekiti yosamalira madzi ndi gawo lofunika kwambiri pa zachuma ndi zomangamanga, zomwe zimagwira ntchito yofunika kwambiri pa chitetezo cha kusefukira kwa madzi, kugwiritsa ntchito madzi, kukonza zimbudzi ndi kuyeretsa madzi. Chitetezo cha kukonza madzi n'chofunikira kwambiri pamakampani amakono amadzi.
Malo opangira magetsi (malo opangira magetsi a nyukiliya, malo opangira magetsi a mphepo, malo opangira magetsi a dzuwa, ndi zina zotero) omwe amasintha mphamvu zosaphika (monga madzi, nthunzi, dizilo, gasi) kukhala magetsi ogwiritsidwa ntchito m'malo okhazikika kapena mayendedwe.
Mafuta ndi gasi ndiye mphamvu yaikulu m'mafakitale osiyanasiyana. Kutulutsa, kukonza ndi kugawa kumafuna njira ndi njira zovuta. Kugwira ntchito ndi njira zotere kuli ndi mphamvu zoopsa motero kungafunike malamulo ndi miyezo yokhwima kwambiri pazida.
Monga momwe mfundo za dziko zimasonyezera, makampani opanga zombo ayenera kusunga mphamvu ndikuchepetsa mpweya woipa, ndikuchepetsa kuipitsa chilengedwe. Ma valve ambiri odziyimira pawokha ayikidwa pa zombo zazikulu ndi zazing'ono, zomwe zimachepetsa mphamvu ya ogwira ntchito ndi antchito. Zombo zina zomwe zingagwiritsidwe ntchito ndi zombo zonyamula anthu/zonyamula katundu, zombo zonyamula katundu wamba, zombo zotengera, zombo zonyamula katundu za RO-RO, zombo zonyamula katundu zambiri, zonyamula mafuta ndi zonyamula mafuta amadzimadzi.
Mu makampani ambiri a HVAC, kupanga mankhwala, zombo ndi sitima zapamadzi, zitsulo, mapepala ndi zina zitha kusinthidwa malinga ndi zosowa za mayankho ndi ntchito zabwino kwambiri.
