Kuti uderedze kupisa kupisa nekuita uye convection, iyo dewar flask ine madziro maviri akapatsanurwa necuum.
Iyo dewar flask ndiyo mhinduro yakakwana yekuchengetedza mvura magasi uye kuitisa yakaderera-tembiricha kuedza.
Kana uchichengetedza dewar flask, ita shuwa kuti inoiswa mune yakanyatsonaka, yakaoma nzvimbo kure neyakajeka zuva, kure nezvinhu zvinopisa uye kupisa masosi.
Ita shuwa kushandiswa kwakachengeteka kweDewar Cylinders uye kuderedza zvinogona kuchengetedzeka njodzi.
Kurapa Cryogenic Liquid Oxygen Dewar Cylinders ndiyo yakakosha yekumanikidzwa mudziyo, inonyanya kushandiswa mumunda wekurapa wekuchengetedza uye kutakura mvura okisijeni.
Dewar madyinders anoshandiswa zvakanyanya kuchengetedza akasiyana-siyana eCryogenic media, ayo anotamba basa rakakosha muminda yakasiyana yekushandisa.
Kubudirira kweDewar tangi kunowanzo kuve kwakadzivirirwa nekushambadzira kwayo kwekushambadzira, ndechimwe chiyero chekuti kupisa kunopinda sei tangi uye kunokonzera iyo cryogenic mvura yekuputika.
