Raketec: The Multiple Rake Screen


Raketec is a multiple-rake bar screen system with no moving parts under grade level. It is a two-chain, free sprocket mechanism guarantying reliability and ease of use. A combination of stainless steel rakes, and durable brushes thoroughly cleans debris from the screen.


1. Simple design
The gear motor, mounted at the top of the frame, rotates the drive shaft. The links of the chain fit into two cogwheels, located on each extremity of the drive shaft. Driven by the rotation of the shaft, the links of the two stainless steel chains slide into the HDPE track. With the HDPE track system, there is no friction between the chain and the frame of the bar screen. There is no requirement to grease the chain.    

2. Free Sprocket, no lower maintenance
At the lower part of the bar screen, the chains slide over two HDPE stationary rollers. With no moving parts at the bottom of the machine, no maintenance or underwater operation is necessary.

3. High Capture Rate
A combination of stainless steel rake teeth and brushes attached to the drive chains, placed one foot apart from each other, allows for extremely efficient cleaning. The brushes captures all rags and wipes, while the stainless steel teeth assemblies clean between the bars of the screen to remove smaller debris such as grit, sand, and fibers.    

4. Minimal & Easy Maintenance
With no moving parts at the bottom of the bar screen, no maintenance is required. The weekly maintenance consists only of a visual check of the chains and the discharge chute. The back of the bar screen has an easy and safe access hood. If needed, brushes and teeth rake can be replaced quickly and easily by unfastening three bolts.    

5. Odor Control
The frame of the bar screen is completely enclosed, keeping odor contained. Adding a washer/compactor with a bagger system, such as Compactec, maintains total odor control.
