COARSE BAR SCREENS

PURPOSE

Bar racks with a bar spacing of a few centimeters are installed across water channels to prevent the downstream ingress of divers, medium or large-size debris. They are used on cooling tower outlets and water intakes.

DESCRIPTION

  • The bar rack with vertical, parallel bars is slid into slots in the civil engineering structure.

  • The water flows through and the larger debris are retained on the upstream surface.

  • It is cleaned manually when the flow of water is stopped and the bar rack is lifted up.

  • It is designed for applications with a small quantity of debris.

ADVANTAGES

  • Very simple and robust

  • Fail-safe

  • Low head-loss

  • Protects against diver ingress

  • Prevents large debris from entering the water channel

  • Very robust (1.5 m design head-loss).

SIZE RANGE

  • Bar spacing from 40 to 200 mm (1.5 to 8”)

  • Widths: up to 6 m

  • Heights: any height is possible with superimposed elements

NECESSARY ANCILLARIES

  • Lift chain

  • Lift beam (for layouts using superimposed elements)

MATERIALS

  • For fresh-water applications:      
    All painted carbon steel or AISI 304L 

  • For seawater applications:          
    Painted carbon steel with anodes          
    AISI 316L or duplex stainless steel
