Geiger Cable-Operated Grab Cleaner / Bar Screen

Geiger® / Passavant® Cable-Operated Grab Cleaners are heavy-duty coarse screening systems designed for reliable removal of bulky debris and sediments from water intake structures, protecting downstream equipment and ensuring uninterrupted plant operation.

Features

Available as stationary or traversing (movable) units for single or multiple intake channels
One grab cleaner can serve three or more channels, reducing capital and installation costs
Intelligent, fully automated cleaning operation
High grabbing force for reliable removal of bulky debris, sand, gravel, and sediments
High load capacity suitable for severe intake conditions
Adjustable carriage speeds for descent and cleaning cycles
Cleaning cycle can be initiated from any grab cleaner position
Exact limitation of lifting movement for safe operation
Slack-rope control system for automatic blockage detection and cycle initiation
Polyamide hose drums minimize wear and extend service life (award-winning design)
Suitable for new installations and easy retrofitting into existing intake structures

Geiger High capacity revolving chain screen/ Multi raking machine/ Rotating chain rake screen

The Geiger® High-Capacity Revolving Chain Screen is a heavy-duty rotating chain screening system designed for reliable coarse and fine screening, providing maximum protection against large and sudden debris loads in water intake applications.

Features

High cleaning efficiency due to minimized gap between screen bars and rake teeth
Precisely guided chain movement on both sides for stable and reliable operation
Polyamide sprocket segments for smooth running, reduced noise, corrosion resistance, and grease-free operation
Highly adaptable design with interchangeable cleaning elements for different debris types (jellyfish, sea grass, fish, algae)
Optional special buckets for handling jellyfish and high algae loads
Excellent cleaning performance when equipped with Vee-Wire bar screens
Simple, robust construction ensuring high reliability and long service life
Low maintenance requirements with minimized OPEX and lifecycle costs
Short cleaning intervals for superior protection during peak debris events

Geiger Claw screen/Gripper Rake

The Geiger® Claw Screen is a heavy-duty coarse screening system designed as a first-stage cleaner for water intakes and pump station inlets, efficiently removing extremely bulky debris and large obstacles to protect downstream equipment.

Features

Extremely robust design capable of handling very heavy and bulky debris, including tree trunks
Highly economical solution, with a single claw unit serving multiple channels or wide bar screens
Monorail-mounted traveling system for flexible multi-channel operation
Direct discharge of debris into a trash container, eliminating the need for concrete collectors or intermediate transport
Low-maintenance design with minimal wear components
VFD-controlled smooth start/stop motion to extend service life of mechanical components
High positioning accuracy enabled by the Geiger® tracking system

Geiger high capacity drum screens

Geiger® High-Capacity Drum Screens are advanced filtration systems installed downstream of coarse bar screens or trash rakes, designed to protect circulating water pumps and downstream equipment by efficiently removing fine debris from cooling water, seawater, raw water, and wastewater intake systems.

Features

High-capacity screening performance up to 140,000 m³/h per channel (framed drum screens)
In-to-out flow design with double-sided entry ensures low hydraulic losses
No buoyancy: static and dynamic forces act vertically and are absorbed by civil structures
Automatic backwashing using spray water jets aided by gravity for maximum cleaning efficiency
No debris accumulation on channel floor below the drum
Designed for an operational service life exceeding 40 years
Easy access to wash-water nozzles from deck level without stopping operation
Light yet rigid A-frame drum structure (framed design)
Low maintenance requirements and minimized lifecycle costs
Optional impressed-current Cathodic Corrosion Protection (CCP) system to prevent galvanic and microbial corrosion

Geiger Dual-flow (Out-to-In-Flow) Travelling Band Screens

Geiger® Dual-Flow Traveling Band Screens provide high-capacity, reliable fine and coarse screening for water intake systems

Features

High throughput with exceptional operational reliability
Compact machine design using roof-shaped or semicircular mesh panels
Fine to coarse screening capability (200 µm to 10 mm)
Efficient cleaning and reliable removal of coarse debris
No debris accumulation on channel bottom and no buoyancy effects
High-efficiency sealing between mesh panels and chain guiding
Wear-resistant chain guiding on the clean water side
Maintenance-free steel side bar chains with replaceable mesh panels
Gentle fish handling with specially designed fish buckets (Centre-Flow option)
High-efficiency spray wash system with reduced wash-water pressure
Polyamide rollers and sprocket teeth for low wear and smooth operation
Optional Geiger® impressed current cathodic corrosion protection for seawater applications

Geiger Centre-Flow Travelling Band Screens

Geiger® Centre-Flow Traveling Band Screens deliver high-capacity, fine-to-coarse screening with superior cleaning efficiency, compact channel design, and zero debris carry-over for demanding water intake applications.

Features

High throughput with shorter channel length compared to dual-flow or flat panel screens
Fully automated filtration with mesh sizes from 200 µm to 10 mm
Extended screening surface using roof-shaped or half-round mesh panels
Highest cleaning performance with downward-directed spray wash system
No debris carry-over
No debris accumulation on the channel bottom and no buoyancy effect
Effective removal of slippery and floating debris such as jellyfish, frazil ice
Gentle fish handling with optional fish protection buckets
Low-noise, corrosion-resistant polyamide sprocket wheel teeth, easily replaceable and grease-free
Highly efficient sealing between mesh panels, chains, and guides
Adjustable band speed for optimized flow control and screen washing
Optional Geiger® impressed current cathodic corrosion protection for seawater applications
