Kuenzaniswa neyakajairwa ronda refinned chubhu, iyo yekubata inopisa kupisa inoramba yakagadzikana mune yakakura siyana nekushanduka kwetembiricha, saka kupisa kwekushisa kwebimetallic aluminium extruded finned chubhu iri nani pane spiral fin chubhu mune inogumira chubhu pamadziro tembiricha.
Uye zvakare, kana ichienzaniswa neyakakoswa chubhu, iyo bimetallic aluminium extruded fin chubhu ine yakasarudzika corrosion resistance uye yakasimba simba, inokwanisa kumira 4.0MPa mvura pressure yekuchenesa, zvimbi hazvisati zvadonha, hwaro hwebimetallic aluminium extruded chubhu.Iyo chubhu inogona kusarudzwa maererano nekuora kwemvura muchubhu uye tekinoroji yekugadzirisa.Iyo base tube inogona kuve kabhoni simbi, mhangura, simbi isina tsvina, nezvimwe.
