MELT FILTRATION | TECHNOLOGY
existing applications. Its flagship RAS melt filter has reached over 530 units installed world-wide. At Plast 2023 in Milan, Fimic officially presented the latest version, the RAS 800. With a 30% larger filtering surface than the RAS 700, it allows an increase of 40% in production capacity and is the largest model of the RAS series to date. This latest addition to the range of automatic self-clean- ing melt filters allows recyclers to reach a higher hourly production capacity, with the efficiency and simplicity characteristic of Fimic’s filtration technology. It is also fitted with a new radial discharge valve, and because the body is heavier than any other melt filter of this series, comes with two support arms to assist the mobile lid. The second innovation Fimic unveiled last year was the
new SPA 190, which it claims is the biggest screw pump on the market. It enables increases to the hourly production, transporting the melted plastic material from the extruder to the filter without using gears, which are sensitive to contamination and can be damaged easily. Powerfil, the Erema business unit dedicated to supplying high-performance filters, offers two filter models, the Erema SW RTF (backflusher) and the Erema laser filter. Both are available in a wide range of sizes, versions and capacity options. The latest development in the company’s filter technology is the new DischargePro control system which significantly increases the level of automation. It reacts to fluctuations in contamination in the input material by constantly refining and adjusting the rotational speed of the filter scraper disc and discharge screw as and when required. This ensures consistent thickening during melt filtration, which is an important parameter for a constant and economical process and ensures an optimum thicken- ing ratio for a high proportion of filtered contaminates while minimising the proportion of melt in the filter discharge.
Discharge control Depending on the application, material, degree, type and contamination, the new control system has the capability to reduce melt loss during filtration significantly. The company said one of the first customers to compare the DischargePro to the previous Erema laser filter control system could save around 50%. With DischargePro, operators benefit from easier operation due to higher automation and are required to carry out less adjustment work. This saves costs, as less time and labour is required. Robert Obermayr, Head of Business Unit Powerful, said:
“Efficient filtration is essential for a stable recycling process. At Erema, we can draw on 30 years of experience in melt filtration. The new DischargePro control system for our laser filter is a major step forward. It significantly increases the level of automation and makes it much easier for recyclers to master challenging filtration tasks. This applies even when highly trained personnel is missing.” ADG Solutions, a recycling equipment distributor and supplier based in Tucker, Georgia, US, has recently expand-
