Kei te tere haere a Jinbin Valve ki te hanga i ētahi whakakā waro maitai nui-diameter me te rahi o te 2 mita.DN2000ngā ārai whānuiKo te nuinga he takirere pūrerehua porowhita, he ārai rānei. He mea hanga mō ngā paipa rere-teitei me te pēhanga-iti, e whakamahia ana mō te whakahaere i te rōrahi hau me te kati i te rere o te hau i roto i ngā pūnaha tauine nui. Kāore i te pai mō te whakapūhau i roto i ngā whare iti noa, engari he whānuitia te whakamahinga i roto i te maimoatanga hau para ahumahi, ngā hanganga ā-tāone, ngā kaupapa whakapūhau nui me te putanga paowa hei whakarite i te mahi pumau o ngā pūnaha whakapūhau me te maimoatanga hau para. 

Ko te rāngai hiko te kaupapa matua o tana tono, ko te nuinga mō ngā paipa hau me te hau para i roto i ngā tipu hiko wera. Ka tāutahia ki ngā tomokanga me ngā putanga o ngā pā hau e akiakihia ana, e whakaohohia ana hoki e ngā pā hau, ka whakatikatika tika ēnei ārai hau kia tau ai te mura. Ka whakamahia hoki ēnei i roto i ngā paipa hau para matua mō te tango i te whanariki me te whakakore i te nitriti, ka wehe i te rere o te hau i te wā e tiaki ana i ngā taputapu. Hei tāpiri, ka taea te whakauru ki ngā paipa karo i ngā paipa me ngā paipa hau e tomo ana ki te auahi hei whakahaere i te whakawhiti tīmatanga-mutu o te waeine me te tiaki i ngā taputapu. 

Ko ngā ārai DN2000 e whakamahia whānuitia ana mō ngā āhuatanga mahi pāmahana teitei me te puehu teitei i roto i te umanga rauemi hanga, tae atu ki ngā wheketere sima, karāhe me te uku. I roto i ngā wheketere sima, ka whakahaeretia e rātou te hau paru e ki ana i te puehu pāmahana teitei i roto i ngā hiku oumu, ngā paipa hau wera o te pouaka whakamatao kirikiti me ngā paipa tango puehu matua o ngā awheawhe huri. Mō ngā oumu rewa karāhe, ngā oumu pupuhi wera me ngā oumu uku, ka tāutahia ki runga i ngā paipa hau putanga matua hei ātete i te hau paru pāmahana teitei me te whakarite kia tutuki te tukunga o te hau para whakaputa. 

He nui ngā ārai pēnei e whakamahia ana i roto i ngā pūnaha hauhautanga me te tango puehu mō te mahi whakarewa me te keri. I roto i ngā hau wera me te tango puehu i roto i te rino me te maitai me te oumu pupuhi, ka whakahaerehia e rātou te hau para puehu pāmahana teitei hei whakahaere i te rere me te wehe i ngā paipa. Ka whakamahia ngā ārai DN2000 ātete-pahūtanga i raro i te whenua i roto i ngā maina waro me te whakarewa, ka whakanohoia ki runga i ngā paipa hau hau matua hei whakarite i te nui o te hau i raro i te whenua. Ka whakamahia hoki ki ngā paipa tango puehu matua mō ngā awheawhe kuru me te tirotiro hei whakarite i te haumaru hauhautanga i te papaanga. 

I roto i te mara o te tukatuka hau para taiao, ko te nuinga o ngā whakakā DN2000 ka tāutahia ki ngā paipa matua o ngā whare tukatuka nui. Ka mahi tahi rātou me ngā tahunga hau para RTO me RCO hei whakatikatika i te rere o te hau para rauropi me te whakawhiti i ngā paipa, ā, ka tautoko i te whakahaere i te rōrahi hau me te tiaki i te wehenga mō ngā whare putea nui me ngā kaiwhakaoho hiko. He pai hoki mō te tukunga hau para mai i ngā tipu tahu para, ngā awa tango haunga, te tuku hau koiora i te whenua ururua, tae atu ki ngā paipa hau waikawa, kawakore me te para tukatuka i roto i ngā tipu matū. Ka taea te whiriwhiri i ngā rauemi ātete-waikura i runga i te reo. 

Mō ngā hanganga kawe waka ā-tāone, ko te hauhautanga me te putanga paowa i roto i ngā kauhanga me ngā pūnaha tereina he āhuatanga tono noa. I roto i ngā kauhanga roa o ngā huarahi tereina me ngā tereina, ka whakamahia e ngā paipa hauhautanga matua me ngā putanga paowa ēnei ārai mō te hauhautanga auau me te putanga paowa ohorere mēnā ka puta he ahi. Ka whakaū hoki i te rere o te hau i roto i ngā paipa putanga o te teihana tereina, ngā paipa tuku hau pēhanga pai me ngā pūnaha putanga hau o te kauhanga wāhanga hei whakarite i te hauhautanga me te haumaru ahi mō te kawe tereina. 

Mō te HVAC me te tiaki ahi i roto i ngā whare nunui me ngā whare ahumahi, ka tāutahia ēnei ārai hau ki ngā paipa hau matua anake. E whakamahia ana ngā tauira ātete ahi pāmahana teitei 280℃ mō ngā paipa hau hou me ngā paipa hau putanga o ngā wheketere nunui me ngā pokapū raraunga tauine nui, tae atu ki ngā paipa hau putanga paowa matua i roto i ngā teihana tereina tereina, ngā pokapū whakaaturanga me ngā whare whenua o raro whenua, e tutuki ana i ngā ture hauhautanga ahi mō ngā tono wāhi nui me te nui o te hau. 

E hiahiatia ana ngā whirihoranga ārai ritenga mō ngā āhuatanga mahi rerekē: ka tīpakohia ngā takirere pūrerehua hiri-mārō maitai waro mō ngā taiao pāmahana teitei me te puehu i roto i ngā tipu hiko, i ngā tipu sima me ngā mira maitai; ka whakamahia ngā momo ātete ahi pāmahana teitei mō ngā putanga paowa kauhanga; ka whakamahia ngā rauemi kowiri tira, ngā rauemi arai rānei mō ngā āhuatanga matū waikura; ā, me whakamahi ngā whakatere ātete-pahūtanga mō te keri whenua kia tutuki ai ngā whakaritenga mahi haumaru mō ngā āhuatanga mahi uaua.
