Ngakhale mu makina opangidwa bwino kwambiri oyeretsera kutentha, kutentha pang'ono kungayambitse mavuto—kutayika kwa zinthu, ndalama zowonjezera zamagetsi, ndi kutsika kwa magwiridwe antchito. Apa ndi pomwemavavu otetezedwa ndi vacuumamakhala ngwazi zosaimbidwa. Si ma switch okha; ndi zotchinga zoletsa kutentha. Akaphatikizidwa ndiMapaipi Otetezedwa ndi Vacuum (VIP)ndiMapayipi Otetezedwa ndi Vacuum (VIHs), zimathandiza kupanga malo otsekedwa komanso okhazikika komwe kusintha kwa kutentha kumakhala kochepa.

Ma valve ambiri amatha kutsekereza kuyenda kwa madzi, koma HL Cryogenics amawapanganso kuti atsekeretse kutentha. Mainjiniya pano asintha kapangidwe kake kakale, kuwonjezera zipinda zotsukiramo mpweya ndi zomatira zokhala ndi zigawo zambiri zolimba kwambiri kotero kuti mpweya wofunda umalephera kudutsa.Mapaipi Otetezedwa ndi Vacuum (VIP)ndiMapayipi Otetezedwa ndi Vacuum (VIHs), ma valve awa amatambasula nthawi yogwirira ntchito, amachepetsa kufunika kobwezeretsanso madzi, ndipo amasunga makina pa intaneti kwa nthawi yayitali popanda kulowererapo.
Ma valve awa si zitsanzo za labu zokha. Amapangidwa ndi chitsulo chosapanga dzimbiri chapamwamba, amayesedwa kuti awone ngati ali ndi cryogenic shock, ndipo amaikidwa ndi timitengo tosatentha. Gulu lililonse limayesedwa—osati kokha ngati pali kutuluka kwa madzi, komanso ngati likugwira ntchito bwino pansi pa kupsinjika kwa kutentha mobwerezabwereza. Kuyambira malo osungiramo LNG pa doko la mphepo mpaka mizere ya nayitrogeni yamadzimadzi mu labu ya biotech, amagwira ntchito mogwirizana ndiMapaipi Otetezedwa ndi Vacuum (VIP)ndiMapayipi Otetezedwa ndi Vacuum (VIHs)kuti kutentha kukhale komwe kukufunika.

Akagwiritsidwa ntchito m'munda, ma valve amenewa amakhala ndi mphamvu yothamanga: kunyamula LNG koyera, kusungirako nayitrogeni yamadzimadzi kotetezeka, kukhazikika bwino kwa maukonde a gasi m'mafakitale, komanso kugwira ntchito bwino kwa malo ofufuzira olondola kwambiri. Zotsatira zake sizongogwira ntchito bwino kwambiri—koma zimawonjezera kudalirika komanso chitetezo m'makina onse.
Kutayika kwa chimfine sikungokhala vuto la uinjiniya—ndi mphamvu zomwe zimawonongeka komanso kuchuluka kwa mpweya woipa. HL Cryogenics imagwiritsa ntchito njira ziwiri: kuwonjezera mphamvu pogwiritsa ntchito nzeru.Ma Vavu Otetezedwa ndi Vacuum,Mapaipi Otetezedwa ndi Vacuum (VIP)ndiMapayipi Otetezedwa ndi Vacuum (VIHs), pamene tikuyesetsa kuchepetsa kugwiritsa ntchito mphamvu. Sikuti ndi ukadaulo wamakono wokha—ndi maziko a makampani opanga magetsi okhazikika.
