Hermetic High Temperature Heating Circulator ine tangi yekuwedzera, uye tangi yekuwedzera uye yekutenderera system ndeye adiabatic. Iyo inopisa svikiro mumudziyo haibatanidzi mukutenderera kwehurongwa, asi inongobatanidzwa nemichina. Hazvina mhosva kuti svikiro rinopisa muhurongwa hwekutenderera rakakwirira kana rakaderera, svikiro mutangi rekuwedzera rinogara rakaderera pane 60 °.
Iyo yese system ndeye hermetic system. Nekupisa kwakanyanya, hazvizokonzeri mhute yemafuta; ine tembiricha yakaderera, haitore unyoro mumhepo. Mukushanda kwekushisa kwakanyanya, kudzvanywa kweiyo system hakuzosimuke, uye mukupisa kwakadzika kushanda, iyo system inozowedzerwa thermal medium otomatiki.
