Material removal from the bar rack starts at a tangent to the channel bottom so that any accumulation of screenings is eliminated. The optimal approaching flow conditions and large effective bar rack surface ensure a high hydraulic throughput capacity under any operating conditions.
The curved bar rack is cleaned by a rake. Depending on the bar spacing, the bar rack design is either a bar or non-blocking wedge wire profile. At the end of the bar rack cleaning cycle the rake is cleaned by a pivoted comb discharging the removed screenings into a downstream unit. As the cleaning velocity is variable, the screenings discharge capacity is adjustable. This is particularly beneficial in the case of increased screenings loads, e. g. due to sudden peak loads.
The easy to access and maintain drive unit is installed above the channel. The compact frame of the CurveMax® Screen allows for a low installation height above ground level. A mechanical linkage converts the rotating movement of the drive motor into a curved track.
