Aqua Caiman Articulating Rake Screens Provide Robust, Low-Maintenance Option for Advanced Screening

Building off over 40 years of in-channel screening experience, Parkson’s Aqua Caiman in-channel articulating rake screen was designed with the operator in mind, providing a low-maintenance and robust option for headworks screening, protection of pumps and downstream processes, and onsite pretreatment. Parkson’s line of three Aqua Caiman screens are made in the U.S. and suitable for both municipal and industrial applications.

The original design features a robust frame and cross supports, bar shapes optimized for reduced headloss, and discharge heights up to 30 feet. A series of rakes attached to chain links form a flexible belt assembly to lift and remove large solids with ease and without the need for lower bottom bearings or sprockets. 

All models allow for chain adjustment without a hoist, and units in a vertical inclination additionally include the True-Grip chain-retention system for additional rake engagement, and the Expulsionator deflector system for aid in solids removal from the rakes.

Vertical mounting

The new Aqua Caiman Vertical screen was designed to accommodate applications where channel requirements are tight and require steep or vertical mounting, or where additional rake engagement force is desired for removing solids from bar racks. The unit mounts vertically at 85 or 90 degrees with discharge heights up to 50 feet and can be used in new or existing deep channels.

Heavy solids handling

Also new, the Aqua Caiman HD screen is even more robust, designed to handle high flows and heavy solids with ease. The unit features a heavy-duty frame and chain links, with bar openings from 1 to 4 inches to accommodate removal of large objects, and a discharge height up to 50 feet. It is suitable for combined storm flow, trash rake and other high-flow applications.
