FlexRake® GTS

Global Technology Screen

¼ in – ½ in bar openings

The advantage of FlexRake® Adaptive Technology™ for high solids applications

Cost-effective screening for low flow, high solids applications

The FlexRake® GTS is designed to serve septage receiving stations, prisons, nursing homes, hospitals, and other applications with heavy solids loading.  It is a fine bar screen available in ¼ inch, ⅜ inch and ½ inch openings. There are in-channel and tank models (piped-in, piped-out) options. 

Our story is simple

The FlexRake GTS – Global Technology Screen has three unique product offerings for low flow screening applications but with a unique value proposition for customers with sites that have heavy solids loading.  As has been consistent with the history of Duperon Corporations ability to invent, the GTS  modified its Jam Evasion™ Technology with a fixed drive head that can be adjusted to site conditions, flex/pivot around large debris all while assuring the engagement into the screen to provide critical movement of heavy solids concentrations.  These features allow a plant or facility with very difficult conditions such as a system ‘flush’ to dry or minimal flows to operate without issue.

Applications:

  • Septage receiving
  • Prisons
  • Nursing homes
  • Hospitals
  • And other low flow, high solids applications

FlexRake® GTS

Automated solution

Simple and cost-effective mechanical bar screen option for low flow, high solids sites 

Proven FlexRake technology

Adapts to a range of unpredictable flow and debris conditions without shutdown or operator intervention  

Low cost of ownership

With few parts, a fractional horsepower motor, and minimal maintenance, the FlexRake GTS is easy to install, own, and operate by your crew

Designed for duty

Engineered to perform in fine screening applications that have low flows and high solids loading

Optimized engagement

Specially designed drivehead is site-adjustable to allow Jam Evasion™ to flex/pivot around debris and also ensures optimal engagement in the screen to avoid blinding in heavy solid conditions 

Tank models available

Piped-in, piped-out option for sites that don’t have channel infrastructure

How can we help

Description

The FlexRake® GTS is a simple front-clean, front-return mechanical bar screen. It features the SmartLink™ multifunctional link system, which eliminates underwater sprockets, bearings or tracks that create a fixed path of travel and are subject to fouling and/or jamming.  The SmartLink design is engineered for long product life and has no minimal water level requirements. The groundbreaking Jam Evasion™ Technology allows the FlexRake GTS to flex/pivot to remove irregular debris or high solids gluts (i.e. bedsheets, jumpsuits, adult wipes, etc).

Key Features

Tear-drop shaped welded bars provide highest efficiency in the industry; 25%-50% more efficient (depending on the bar opening)

SSTL Thru-Bar™ scrapers clean all three sides of the bar and cross member

Proven Duperon® FlexRake® technology: no lower bearings, sprockets, jam points or confined space entries

UHMW & SSTL SmartLink™ is completely corrosion-resistant, provides long life and is self-lubricating material

UHMW and SSTL SmartLink allows for “dry” operation  which is ideal for low flow sites with varying water levels since there is no minimum depth required
