“We have put a lot of effort into developing this technology. I am therefore particularly delighted to accept this award on behalf of the entire team today,” says Robert Obermayr, Head of the Powerfil business unit at Erema, at PRSE 2024 in Amsterdam. The Discharge Pro system automatically compensates for fluctuations in the input material, thereby ensuring uniform thickening during melt filtration and thus a consistent process. Depending on the application and contamination, Powerfil was able to reduce melt loss by up to 50 percent with the DischargePro compared to the previous Erema laser filter control system. These facts convinced the jury, who described the technology as an intelligent technological advance in the extrusion process.
With the DischargePro control system, Powerfil significantly increases the degree of automation in the filter process. The innovative discharge control system reacts to specific disruptions in the process. In this way, the speed of the scraper star is adjusted at short notice and returns to the setpoint speed as soon as the contamination peak has been discharged. Furthermore, the control system also recognizes changes in throughput and adjusts the discharge rates accordingly. In the event of a higher pressure drop across the filter screen, which is caused by a higher viscosity of the melt, DischargePro adjusts the setpoint value to ensure a consistent discharge rate. Long-term changes, such as the condition of the filter screen, are also taken into account in all adjustments.
