Absolute Protection of Downstream Processes.

No dynamic seals to wear and ultimately fail.

Perforated Screen

    Duperon® Perforated Plate Technology Description

    Duperon® Perforated Plate Screens are different from other perf plate screens because they do not rely on dynamic seals. Dynamic seals start to wear from day one and ultimately fail. This puts the process they protect at risk.

    The Duperon® Perf Plate uses a fixed-element screen, which creates an ABSOLUTE BARRIER to damaging debris. This eliminates the possibility of leakage or carryover. Instead of using brushes to clean the screen, the hydrostatic pressure of the flow is managed at each hole using a device we call an “Effector™”. This method is known as Active Hydropression™. Skimmers pass over the front of the screen in tandem with the Effectors and guide debris to the surface for removal. This system has proven to be quite effective, even against clogging, stapling, and blinding.

    Duperon® Perforated Plate Technology Features & Benefits

    Absolute Protection:

    Uses a fixed-element screen, which provides absolute protection for downstream processes (even in the event of a mechanical failure).

    Active Hydropression™:

    Cleans each individual hole by managing the hydrostatic pressure, which allows efficient low-volume, low-pressure jet cleaning. Proven effective against clogging, stapling, and blinding.

    Corrugated Screen:

    The corrugated geometry of the screen increases screen strength and provides improved headloss dynamics compared to flat screens.

    Proven FlexLink™ Technology:

    Duperon® Perforated Plate screens employ proven FlexLink technology which has been used for decades on FlexRakes.

    Millennial™ Platform:

    The modular Millennial Platform supports future design developments and makes it possible to make changes to meet future process requirements.
