Amagwiritsidwa ntchito ngati thanki yosakaniza, thanki yosakaniza, thanki yogwedezeka, thanki yowonongeka, etc. Zabwino m'madera monga zakudya, mkaka, zakumwa zamadzi a zipatso, pharmacy, makampani opanga mankhwala ndi biological engineering etc.
Tanki yozizirira yamkaka ili ndi mtundu wopingasa, woyimirira, mtundu wa U mawonekedwe amitundu itatu, imatenga thovu la Polyurethane kuti lisungunuke. Mankhwalawa ali ndi mapangidwe apamwamba, teknoloji yopangira zinthu, ntchito yodalirika, kuziziritsa, ntchito yosungira kutentha ndi miyezo yaukhondo ikugwirizana ndi mlingo wapadziko lonse lapansi.
Ntchito yaikulu ya thanki ya firiji ndi kusunga mkaka watsopano. Mkaka wofinyidwa kumene umawonongeka mosavuta ngati wasungidwa kutentha kwa firiji. Iyenera kuyikidwa m'chidebe chokhala ndi kutentha kochepa. Chitsanzo cha thanki ya firiji chikugwirizana ndi zotsatira. Tanki ya firiji ya 500L itha kugwiritsidwa ntchito. Imakhala ndi 500 kg ya mkaka. Tanki ya firiji imagwiritsa ntchito kompresa kuziziritsa mkaka. Zida zonse zimapangidwa ndi SUS304 chitsulo chosapanga dzimbiri. Matanki akuluakulu a firiji ndi ovuta kuyeretsa. Ili ndi mutu wa CIP sprinkler wowunikiridwa wokhazikika wokhazikika komanso chipangizo chodzidzimutsa kuti chiwothe. Chosanjikizacho chimapangidwa ndi thovu la polyurethane ndi ntchito yabwino yotchinjiriza kutentha.
