Heat Trace and Blanket Kit: can be thermally protected from cold temperatures with the addition of the Heat Blanket with integral heat trace. Note this is required in applications where freezing temperatures are possible.
Drop Sleeve: A flexible, heavy-duty urethane canvas sleeve can be connected to the end of the Shaftless Screw Conveyor steel chute. The sleeve shall provide a guidance for dropping screenings to help contain the debris as it falls and prevent debris from being scattered.
Hinged covers: Covers can be provided with a hinge on one side and a quick connect clamp fitting on the other. :
Duperon has sluicing down to an art
The Duperon sluice is a simple conveyance method using a stainless steel trough and flowing water to transfer discharged screenings. In municipal applications, sluices typically discharge into washer compactors for dewatering. In other applications such as flood control or raw water intakes, it may discharge downstream of the site or be transported to a bank or holding area.
This system of transport is often ideal when discharging from multiple screens, the site has long runs to move the debris to the final discharge point. A sluice may be cost effective by eliminating belts, multiple drives and other mechanical devices.
Our solutions are simple
There are basic factors that attribute to a successful sluice operation: debris volume management, water conversion (minimizing water usage while maintaining functionality) and velocity.
Duperon has implemented many sluices over the years and has mastered the distinctions across many industries and applications to assure that this option is successfully applied and engineered to your site.
Applications:
- Municipal Wastewater
- Industrial Applications
- Stormwater and Flood Control
- Open Channel Intakes
- And other wetted solids transport applications

Description
A Duperon Sluice is a conveyance device that is ideal for long spans where the costs of multiple belt conveyors, or mechanical devices like augers, becomes prohibitive. Also sites realize additional economic benefit if they require turns or accommodations for existing structures, especially if they have an ample water supply.
The Sluice is constructed of non-corrosive materials such as stainless steel in the form of a trough. A pump will be sized as appropriate for the water volume required, as well as considerations for the number of screens discharging, the type and volume of debris.
It is often discharging into a washer compactor for dewatering (for municipal wastewater or industrial applications) or into other desired locations for raw water intakes or stormwater, flood control applications.
