WASTE WATER SolutionsHUBER Belt Screen EscaMax ®Perforated Plate ScreenVersatile inlet screen– Excellent separation efficiency due to its perforations– Reliable cleansing of the perforated plates with a rotatingbrush– Very compact system with minimum space requirements– Easy-to-retrofit into existing channels

➤ Design and functionThe HUBER Belt Screen EscaMax® complements thewell-known HUBER program for municipal and industrialwaste water screening, as it is particularly well suited insituations where excellent separation efficiency isrequired in deep channels with high water levels.Perforated screening elements provide superiorseparation efficiency in comparison with slit screeningelements. It has been determined that two-dimensionalperforations are better than one-dimensional slits.Formation of screenings rolls is prevented by rake barsextending over the full width of the screen in combinationwith the screen's installation angle. Even cans and bottlesare lifted by these rakes.Each end of the perforated plates is connected with adrive chain. Each chain is driven by a sprocket on acommon shaft and a flange mounted gear motor.At their upper turning point the perforated plates arecontinuously cleaned by a fast counterrotating brushwhich increases the cleaning energy and thus signifi -cantly improves the cleaning efficiency. Cleansing issupported by an integrated spray bar.The sturdy HUBER Belt Screen EscaMax® is able toreliably cope with even high amounts of gravel and grit.The two-dimensional screening elements preventespecially long fibres from passing through the screenand achieve thus the maximum separation efficiency.Flow diagram of a HUBER Belt Screen EscaMax®

WASTE WATER Solutions➤ The challenge – Our solutionWe have been challenged to provide screens combiningever increasing separation efficiency with operationalreliability. The EscaMax® Screen is our answer to thischallenge.State-of-the-art design of a perforated plate screen thatguarantees the highest efficiency, lowmaintenance and long life required attention to everydetail.Our Perforated Plate Screen EscaMax® sets newstandards, due to its innovative features.➤ Functional details of the HUBER Belt Screen EscaMax®Innovative cleaning system with a rotating brushThe distinctive feature of the innovative perforatedplate cleaning system compared to other state-of-theartsystems is its significantly improved efficiency due toits special arrangement and counterrotating brush.Other systems require an additional scraper roller toremove screenings from the trough edge.A counterrotating brush eliminates this problem so thatno additional scraper roller is required for trough edgecleaning.Wear-resistant plastic elements ensure proper sealingbetween the travelling screening elements andthe frame whilst the perforated plates are moving. Theconnection between the plastic and screening elementsis designed to allow quick and easy replacement.The submerged chain wheel bearing consists of ahighly wear-resistant and maintenance-free ceramicbearing which has proven its reliability for years in ourgrit washing plants.The drive chain is made of hardened wear-resistant steel.The chain and chain wheels are electrogalvanised andyellow chromated for durable corrosion protection. Asan option, the chains and chain wheels are available instainless steel.counterrotatingbrush roller
