Ukuhlolwa rhoqo kwe-flasks kunye nembonakalo iyafuneka ukuba iqiniseke ukuba izixhobo zikhululekile, zikrexeza, okanye eziya kuthi ziyeke iiflethi ze-Dewar ekuphumeni.
Iiflethi ze-Dewar zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezinjengophando lwezenzululwazi, ukuqhutywa kwezonyango, ukuphononongwa kwangaphandle, kunye nokusetyenziswa kwekhaya.
I-Dewar esebenza nzima ye-Dewar yenzelwe ukubonelela ngokufakwa okuphezulu kwe-shirt, iyongela ukuba izicelo zifuna uzinzo lweqondo lobushushu lwexesha elide.
I-Dewwar Tank ibandakanya izinto zokufakwa kwe-themores-the-ye-artic enciphisa imitha ye-thermal kunye nokudluliselwa kobushushu. Oku kuqinisekisa ukuba ama-cryogens yakho ahlala kwiqondo lokushisa labo lexesha elide, ukunciphisa iindleko zokusebenza kunye nokuphucula ukusebenza kakuhle.
Ukusebenza kakuhle kwetanki yokupheka kudla ngokusetyenziswa ngumgangatho wayo wokudlulisela ubushushu, umlinganiso wendlela ubushushu bukhawulezile kangakanani itanki kwaye ubangela i-crygenic ulwelo.
Umsebenzi ophambili wetanki yokuphefumla kukugcina amaqondo obushushu aseSetriogeds obambeleyo.
