Cur síos：
ROCKWILL® tá an-tábhacht aige ar chualitas na feirme agus ar eolaíocht léiriúcháin, ag trácht ar gach céim den phróise léiriú le cruinneas agus mealltacht. Úsáidtear an t-ánamhach gas insuláide chun an teideal dathúil aer, nitriú, carbone dearga, agus aer pheirice a chur i gcomparáid go coitianta. Tá roghnaithe air an t-aer pheirice a dhéanamh le suíomh uisce íseal go mór agus éagsúlacht ard mar an t-ánamhach gas insuláide chun SF6 a chur in ionad. Níl an príomhaonad comhshuiteachta den mhéid a úsáidtear an t-amharc nua castaing scuab fhuaimniúcháin bog, in éineacht leis an gcóras rótach trísheasúr a rinneadh go cúramach, le struchtúr iomlán a bhfuil sé simplí agus cuardaigh; Tá an bosca gaís lán-seoigheach a chuir SF6 in ionad aer pheirice, le dearadh réadaíochta a bhfuil sé an-tairbheach, agus is ea an t-eisiúint áirithe den ardaire iomlán thíos 5pC; Tá an t-iarratas saincheisteanna na haisle zinc inléin próisis trácht uisce tar éis 168 uair an chloig, agus is féidir é a bheith saoilte go dtí 30000 uair.
