MAAG Group presents a new continuous screen changer design that enables higher throughput or energy efficiency by up to 50% while optimizing material usage: the CSC-230R-DV with integrated DV position.

This system is specifically engineered for processing copolymers such as EVA, ABS, or SAN, which may cause deposits, wear, and elevated energy consumption in conventional long melt flow systems. The goal is to process sensitive polymers under stable conditions with maximum efficiency.

Sensitive Materials Require Special Handling

The processing of copolymers requires precise temperature control and minimized residence time on the production line. Existing market solutions often rely on multiple melt adapters and additional startup components, such as startup-valves, which extend the flow channel or offer only small round or oval filtration areas. This requires higher energy consumption and can leads to reduced polymer quality, and limited economic viability. Many systems also require frequent screen changes and longer startup times, resulting in downtime and production waste.

For applications involving sensitive polymers like EVA, ABS, or SAN—as well as other shear- and temperature-sensitive materials—precise and consistent melt flow management is essential to avoid quality degradation and unnecessary material loss.

Compact Design for Stable Processes and High Efficiency

MAAG’s CSC-230R-DV features a compact, curved screen design with an integrated DV position. This configuration shortens the melt path, reduces dead volume, and minimizes thermal stress. Depending on the setup, it can deliver up to 50% more throughput or a significant reduction in energy consumption. The startup process is accelerated, startup waste can be reduced by approximately 20%, and production begins with clean screens for maximum service life.

The system stands out for its easy cleaning, user-friendly operation, and minimal footprint. Combined with high filtration performance, it ensures stable operation even with demanding materials. The CSC-R-DV series is suitable for virgin materials, extrusion processes, and applications involving sensitive polymers where thermal protection and energy efficiency are key priorities.
