Katsi ai hpe galai shai ai ladat: Liquid nitrogen vaporizers ni gaw nbung-hka shin ai ladat (sh) hka-hka shin ai ladat hpe lang ai. Nbung-bath amyu hpe ga shadawn hku la yang, liquid nitrogen gaw, shingbyi shara kaw nna, fins (sh) coils ni hte hpaw da ai heat exchange pipe de lwi shang wa ai. Pipe a shinggan bunghku gaw grup yin na nbung hte hkrak matut mahkai nna, nbung gaw katsi ai shara zawn galaw nna, katsi ai hpe liquid nitrogen de htawt sit ya ai. Liquid nitrogen a grai n-gun n law ai n-gun (boiling point) a majaw, n-gun n law ai grup yin n-gun (ga shadawn, -20℃) hta pyi, n-gun n bung ai majaw, n-gun shayawm ai lam hpe naw shabyin ya lu ai.

Phase Change Process: Liquid nitrogen gaw pipe ni hku nna lwi wa ai shaloi, katsi ai hpe hkap la nna, shi a katsi ai lam gaw kalang lang shi a hka lim ai shara de du wa nna, dai hpang n-gun ja ai hka lim ai lam byin wa ai. Hka lim ai hku nna pru wa ai nitrogen gas a n-gun gaw lawan ladan jat wa ai (liquid nitrogen litre 1 gaw nitrogen gas litre 696 daram byin tai wa lu ai). Pressure hpe vaporizer pru ai shara kaw na pressure hpe hkang ai jak langai mi hte hkang ra ai, dai hku nna pru wa ai gas hpe ngang grin hkra galaw ra ai.
