rainwater recycling chilled water system cooling tower self-cleaning filter
Product structure
Principle descriptions
The water flows through the screen and the particles are retained on the inside of the screen of the filter element. The filtered water then flows out through the outlet.
When the particles accumulated to a certain number and the pressure differential increases to the pre-determined level, the flushing cycle starts.
It include two steps: First, the automatic drain valve opens on the drainage outlet. Then, electronic motor drives the cleaning brushes which are inside the screen, the solids are expelled through the drain valve.
Filters continue to supply filtered water even during the flushing cycle.The whole working system is controlled by a smart box which has several control modes: pressure differential, time, manual and PLC.
DLD series automatic have much advantages:wide filtration range,short flushing time,low water consumption,low pressure loss etc.
