Ko te Turbine a Francis tētahi o ngā turbin e whakamahia nui ana, e kōhikoi ana i ngā āhua o te rere kiwi me te rere aroturuki. Ko te wai ka tīmata ki te kawe i te rere kiwi ki te kaitakaro, kātahi ka hurihia ki te rere aroturuki. Ka tuku mai tēnei hoahoa motuhake i tana mahi pai ki runga i te pāpaku me te pāpaku teitei (30-700 mita) me ngā tikanga rere waenganui.
Ko tana kaitakaro he hoahoa arero kōpere wāhi-nui, e māmā ai te huri i te kaha nekeneke me te kaha totohu o te rere wai ki te kaha hinonga. Ko ia te tauira matua o ngā pūngao wai rahi me te waenganui o te rā nei. 
Ko te roanga o te whārite pūmahara: Ka taea e ia te pupuri i te whārite pūmahara nui ake i te 85% ki roto i te roanga utu 50%-100%, ā, ko te iti noa o ētahi tauira māmuri ka eke ki te 94%.
Te hanganga kaha me te whaimana: Ko te Turbine Francis he rōpere toa miramira nekeneke, he pai hoki te here mo te wera wera, me te ora ratonga nui ake i te 30 tau.
Whakahaerenga māmā: Kua tapaina ki te papanga arataki māmā, ka taea te urupare tere ki ngā panoni i te utu o te ipurangi, ā, he pai hoki te whakahaere taumaha me te whakahaere taumaha.
Māmā te tiaki: Ko te Turbine Francis he rōpere peratia petini me te hanganga wehenga, he māmā ki te tirotiro me te tiaki ki te tūnga tūmatanui.

Ko te Turbine a Francis e tino whai kiko ana mō ngā pūngao wai hauauru ki ngā awa maunga, ā, kua whakamahia whānui i ngā pūngao wai hauwhārite kei te 100-400 mita te teitei o te pū. Kei te mahi pai rawa ia ina whakamahia hei turupene wai i tētahi pūngao wai tāpoi.
Ko te Turbine a Francis he whakamahia noa i ngā pūngao wai rahi, ā, e eke ana te kapai o te kotahi ki te 800MW, neke atu rānei.
Nau mai ki DHC, te tohu tuatahi mō ngā rangapū hau rā whakamahia! Tēnā tā matou mahi hei whakamārama i ngā whakaaetanga hou me ngā pūtake hou, ā, ina whai kē, he pūhanga hau, he pāne tāwhiti, he pouaka lifepo4, ānei.
