节省运行成本
BENEFITS
可是, 注塑机的效能日渐降低(例如,注塑周期变长), 因为系统里 有水垢!
水垢
Water Scales makes Produc;on Less Efficient
Scales
Descaling � System � 電子除垢系統
Bacteria � Inhibiting � Device � 細菌/ � 青苔/ � 藻類抑制系統 �
Water � In � Pipe � 進水管
Filtration � System � 過濾系統
Water � Return � Pipe � 回水管
Drain � Pipe � 排污管
安裝在冷卻塔旁, 絕不侵入 、絕不影響原客戶系統
Placed next to Cooling Towers, No intrusion into Customer’s Systems
