We supply debris filters for protecting the heat transfer equipment against wastes that may have passed through upstream screens. 

 

The Debris Filter is capable of handling various forms of debris/sludge, i.e. suspended particles/matter, mussels, grass, leaves, wood pieces, etc. The strainer effectively prevents fouling by capturing and ejecting all debris in an optimal manner. The optimal cleaning capability is achieved through the incorporation of dedicated suction ports for the two basic classes of debris – coarse and fibrous.

 

When fouling creates the critical predetermined pressure across the filter, the backwash/debris evacuation sequence is initiated. The valve on the debris evacuation pipe automatically opens and the evacuation rotor is actuated. The differential pressure at the portals creates the vacuum by which all the debris is evacuated. The rotor continues to clean the filter until allowable differential pressure exists. The rotor then is automatically stopped and the valve on the evacuation is closed.
