ESS-1655HD™ Decanter Centrifuge

Elgin’s field proven ESS-1655HD2™ decanter centrifuge is the perfect choice whether you are working toward maximizing product recovery or looking to get the most out of your “zero-discharge” closed-loop system.

When solid/liquid mixtures with a high portion of solids need to be separated, decanter centrifuge, also known as a horizontal bowl centrifuge, are the solution of choice.  Used to separate a mixture that consists of two substances with different densities by using the centrifugal force resulting from continuous rotation. It is normally used to separate solid-liquid, liquid-liquid mixtures.

ESS-1655HYD™ Electronically-Controlled Hydraulic Driven Decanter Centrifuge


Elgin’s ESS-1655HD2™ decanter centrifuge is fitted with a NEMA premium, continuous duty, poly-chain driven, 60 hp main drive and a direct-coupled 20 hp back-drive.  The 60 hp main drive can operate the centrifuge up to 3,400 rpm, therefore generating more than 2,300 G’s of force.  Using an inclined motor mount, motor and belt maintenance is made easy by the adjustment of two jack screws.  No additional motor mounts, brackets or tensioning devices are required.  

The ESS-1655HD2™ decanter centrifuge utilizes a carbon fiber poly-chain, no belt retensioning is required after installation is complete.  The carbon fiber tensile cords are length-stable and can withstand shock loads that frequently lead to belt failure.  More importantly, Elgin’s carbon fiber poly-chain will not require quarterly replacement, saving thousands in annual maintenance expenses.     

The 20 hp back-drive coupled with a 56:1 planetary gearbox generates an industry-leading speed differential, which ultimately translates into a larger performance window.  This performance window is what grants the ESS-1655HD2™ decanter centrifuge maximum flexibility when managing the cut-point and the moisture content of discharged solids.  

ESS-1655HD2™ Decanter Centrifuge Touch Screen Control System
To ensure maximum operator flexibility, Elgin has developed a proprietary touch-screen VFD control system.  Each stainless steel, NEMA 4X panel is built from the ground up using the most sophisticated electrical components and Yaskawa™ A1000 variable frequency drives.  Elgin’s VFD systems include a variety of enhanced features including, internal lighting, ventilation and heating, Ethernet porting for diagnostics and programming updates, and a custom designed user interface that allows for maximum operating flexibility and control.  Elgin’s proprietary user interface provides complete control of all systems, as well as, a sophisticated set of diagnostic tools, information libraries and read-only fault logs.  Class 1 / Division 1 explosion proof panels with air conditioning and purged-air protection systems are also available.
