Description
The Duperon Self-Cleaning Trashrack (SCT) is a front-cleaning, rear-return style automated screen. It is designed for tough open channel conditions where debris is large, high volume, or high velocity flows.
Its robust frame and 3000 lb lifting capacity manage everything from severe aquatic vegetation, tree stumps and automobile engine blocks. Whether the goal is flood control, uninterrupted power generation, or pump protection, this unique design assures that debris is brought to the surface automatically and continuously, without operator intervention, all at a pace that can be managed at the deck.
The SCT incorporates the natural dynamic of mat formation to optimize removal efficiencies of both small and large debris. Cleaning occurs simultaneously with multiple chains on each unit across the channel to remove the debris mats.
The Self-Cleaning Trashrack is engineered to be able to sit idle for long periods and ready to move into action when called. Redundancy is built into the design, cleaning the entire intake, with each unit independent, each chain independent and a self-tripping mechanism that means the unit can keep running even when hit hard. When looking for a key tool in building community or process resiliency, the Self-Cleaning Trashrack is your best defense.
The Duperon Self-Cleaning Trashrack is a front-cleaning, rear-return style automated screen used in severe open channel conditions where debris is large, high volume, or at a high velocity. The SCT incorporates the natural dynamic of mat formation to optimize removal efficiencies. The chains support lifting cars that simultaneously clean across the channel to remove debris.
The SCT is ideal for sites that experience high velocities, high flows, and harsh debris conditions. With a lifting capacity of 3000 lbs, the SCT can easily handle heavy vegetation, large refuse, logs and even automobile engines and washing machines
Reliable operationCan stand idle for long periods, yet reliably respond when a storm or debris event occurs
Ensures continuous waterflowMultiple chains across the intake clean all of the screen all of the time. Additionally, the front-cleaning, rear-return operation provides constant flowable area to keep water moving
Continuous CleaningBuilt-in redundancy and automatic reset features avoid shutdown. Each chain operates independently and has self-tripping mechanisms that bypass debris heavier than 3000 lbs for uninterrupted cleaning
SimpleWith few moving parts, no underwater bearings or sprockets, and minimal maintenance, the SCT is easy to install, own, and operate by crew
Applications
- Flood control
- Hydroelectric
- Co-generation
- Nuclear power plant
- Stormwater
- Water intakes
- Diversion dams
- Drainage pump stations
- Irrigation
Key Features
- Lifting capacity of 3,000 lbs
- Can stand sdle for long periods, yet reliably start whenever a storm or rain event occurs
- Built-In redundancy—each chain operates independently, even if one chain strand is out-of-service, cleaning will continue
- Simple self-tripping mechanism allows debris too large or bulky to trip the lifting car rather than shut down the SCT
- No underwater bearings or sprockets
- Cleans all of the screen all of the time
- Front-cleaning, rear-return means lifting fingers do not have to penetrate the upstream debris
- Prevents debris from sliding down, accumulating and blocking screen—water flow is ensured
