Ibikoresho bya HL Cryogenic bimaze imyaka 30 bikora inganda zikoreshwa na cryogenic. Binyuze mu mubare munini wubufatanye mpuzamahanga bwimishinga, Chengdu Holy yashyizeho urwego rwibikorwa bya Enterprises hamwe na sisitemu yo gucunga ubuziranenge bushingiye ku bipimo mpuzamahanga bya sisitemu yo gukwirakwiza imiyoboro ya Vacuum. Sisitemu yo gucunga ubuziranenge bwa Enterprises igizwe nigitabo cyiza, ibyangombwa byinshi byuburyo bukurikirana, amabwiriza menshi ya Operation hamwe namategeko menshi yubuyobozi, kandi bigahora bivugurura ukurikije akazi nyirizina.
Muri kiriya gihe, HL yatsinze amasosiyete mpuzamahanga ya gaze '(inc. Air Liquide, Linde, AP, Messer, BOC) ubugenzuzi bwakorewe ku rubuga maze aba isoko ryabo ryujuje ibyangombwa. Amasosiyete mpuzamahanga ya gazi yemereye HL gukora hamwe nibipimo byayo mumishinga yayo. Ubwiza bwibicuruzwa bya HL bugeze kurwego mpuzamahanga.
ISO9001 Icyemezo cyo gucunga neza Sisitemu Icyemezo cyemewe, kandi ugenzure neza igihe nkuko bisabwa.
HL yabonye impamyabumenyi ya ASME kubasudira, uburyo bwo gusudira (WPS) hamwe nubugenzuzi budasenya.
Icyemezo cyiza cya ASME cyemewe.
Icyemezo cyo Kumenyekanisha CE cya PED (Amabwiriza y'ibikoresho by'ingutu) yemerewe.
