I-Hermetic High Temperature Heating Circulator ifakwe itanki yokwandisa, kunye netanki yokwandisa kunye nenkqubo yokujikeleza i-adiabatic. I-thermal medium kwisitya ayithathi nxaxheba kwi-circulation yenkqubo, kodwa ixhunyiwe kuphela ngomatshini. Kungakhathaliseki ukuba i-thermal medium kwi-circulation system iphezulu okanye iphantsi, i-medium kwi-tank yokwandisa ihlala iphantsi kwe-60 °.
Yonke le nkqubo yi-hermetic system. Ngokushisa okuphezulu, akuyi kubangela inkungu yeoli; ngobushushu obuphantsi, ayizukufunxa ukufuma emoyeni. Ekusebenzeni kweqondo lokushisa eliphezulu, uxinzelelo lwenkqubo aluyi kuvuka, kwaye ekusebenzeni kweqondo lokushisa eliphantsi, inkqubo iya kongezwa kwi-thermal medium ngokuzenzekelayo.
