DESCRIPTION
Fish Recovery and Return Screens for Pump and Condenser Protection
Features
Screens built to site-specific conditions for flow, mesh aperture, debris, and marine life handling
Hydraulically optimized fish buckets and high net panel efficiency reduce velocity and head loss
Descending discharge with inclined mesh reduces spray water and enhances marine discharge
Materials of mainly carbon steel (epoxy coated or galvanized) or stainless steel (304L, 316L, Duplex or other)
Mesh opening is typically 2mm or sizes from 0.5mm to 9.5mm (0.019” to 0.375”) square opening are available
Variable Frequency Drive (VFD) motors incorporate multiple speeds, provide flexibility and user interface
Options
Shaft-mounted drive to reduce maintenance and eliminate shear pins, drive chain, sprockets, and bulky chain guards
Smooth top mesh inserts in square or rectangular openings to provide greater open area
Oversized, non-lubricated carrier chain rollers, pins, and bushings to reduce horsepower and extend chain life
Dual spray headers to provide positive, overlapping coverage for debris removal and flushing
Full rim sprockets to drive the carrier chain via the sidebars, to extend chain life and reduce joint wear
Anti-friction take up bearings for continuous operation to decrease maintenance attention
Chain tensioning from deck level to provide instant access for adjustment and eliminate ladders and platforms
Roll around boot section for positive tracking to eliminate submerged sprockets with constant jamming
Panel-to-panel seals and frame-to-panel seals to eliminate bypassing for fine mesh applications
Manual or automatic self flushing spray headers and debris trough to prevent debris accumulation
Replaceable track wear bars to extend frame life and ease future overhauling of main chain guide tracks
Control systems for Differential Control (ultrasonic or radar) with HMI touchscreen or via DCS monitoring
ADDITIONAL INFO
Benefits
40 years’ experience with thru flow, dual flow, and dual flow conversion fish recovery screens
Numerous laboratory trials and proven results via installation post impingement studies
Design previously approved as BTA to meet impingement mortality standards
High net panel (basket) efficiency reduces through screen velocity and head loss
Large hydraulically optimized fish recovery bucket to induce recovery and improve survivability
Flexible design for adaptability including effective width, depth, mesh aperture, and materials
Components designed for continuous (24/7/365) operation with decreased maintenance
