He whānuitanga o ngā taputapu wehewehe hau e tukuna ana e te kamupene e whakamahia ana i roto i ngā ahumahi maha pēnei i te whakarewa, te hinu matū, me te rererangi. Whakapai ake i ngā tukanga me ā mātou hua kounga teitei.
He wāhanga nui ngā Wāhanga Wehenga Hau (ASU) o te maha o ngā ahumahi, ā, he mahi nui tā rātou i roto i ngā tukanga hanga e hiahia ana ki ngā hau parakore. Ka whakamahia ēnei hei wehewehe i ngā wāhanga hau pēnei i te hāora, te hauota, te argon, te herium me ētahi atu hau rangatira. Ko te mahi a te ASU i runga i te mātāpono o te whakamatao cryogenic, e whakamahi ana i ngā pāmahana kohua rerekē o ēnei hau hei wehewehe pai i a rātou.
