Improve quality with a Fresh Powder System A constant mix of fresh and recovery powder avoids color variations and other quality problems, even with metallic and other special powders.

Fresh Powder System: how does it work? ● The powder hopper is provided with a level probe that monitors the presence of powder. ● When powder level decreases, the level probe activates the fresh powder equipment that feeds virgin powder to the hopper. ● When the powder level is restored, the level probe stops the feed of virgin powder. Level Probe below powder level Level Probe recalls powder © 2015 by Gema Switzerland GmbH - All rights reserved.

Constant Application Quality The recovery powder is different from the virgin powder in terms of: o Particle size distribution Without a fresh powder feed system, the concentration of fresh powder o High fresh powder concentration when virgin powder is manually fed. o Fresh powder concentration gradually decreases until fresh powder is fed again Manual Feeding Fresh Powder Fresh powder % Recovery Powder % © 2015 by Gema Switzerland GmbH - All rights reserved.

Constant Application Quality ● With a fresh powder system the mix of fresh and recovered powder remains much more constant over time. ● Fresh powder is automatically refilled into the hopper every time the powder level falls below the desired level. ● This guarantees much more regular application results.

Reduced manpower ● Without a fresh powder feed system one operator must monitor the line and manually refill powder when needed. ● This can happen more or less often depending from the size of the hopper and from amount of powder used. ● A fresh powder feed system allows the system to work for many hours without any human intervention. © 2015 by Gema Switzerland GmbH - All rights reserved.
