【奧凱無負壓供水設備】 無負壓疊壓變頻供水設備是在氣壓給水設備的基礎上開發的一種能直接與自來水管網連接、且對自來水管網不產生任何副作用的成套給水設備。無負壓疊壓變頻供水設備取代了蓄水池的和屋頂水箱，能充分利用自來水管網的壓力直接或間接供水，避免了能源的二次浪費和水質的二次污染，大幅度節約了基建投資并縮短了施工工期。 Non negative pressure superposed pressure frequency conversion water supply equipment is a kind of direct and water pipe network connection, and does not produce any side effects on the water pipe network of the complete water supply equipment based on the pneumatic water supply equipment on. Non negative pressure superposed pressure frequ
