Continuous screen changer for thermoplastic materials
In plastic processing industries, continuous filtering of thermoplastic melts is critical to maintain product quality. Effective filtration ensures removal of contaminants, preventing defects and increasing the lifespan of the final product. Achieving this without interrupting the production process remains a challenge.
Streamline filtration with automatic screen cleaning
The Screen Changer ESK B by ECON is a continuous double-piston screen changer equipped with a fully automatic backflush system. Designed for processing all thermoplastic materials, it ensures optimal design of the melt flow path, resulting in short melt residence times. The system minimizes pressure build-up, preventing thermal variations within the melt. Its design eliminates dead spots, facilitating quick material or color changes. With approximately 75% effective screen area, the ESK B offers high operational reliability and long durability. The backflush system operates by redirecting the melt flow, allowing one piston to be used in production while the other undergoes cleaning. Backflushing removes contaminants with minimal melt loss, ensuring continuous operation without shutdowns. The ESK B can handle throughputs up to 3,750 kg/hr, making it suitable for a wide range of industrial applications.
