Discontinuous screen changer for low viscosity melts

Filters and Separates Polymers During Production

The Screen Changer ESD from ECON is a versatile discontinuous filtration solution designed for polymer manufacturers and plastic processing companies. This equipment operates by hydraulically moving the piston to change screens when the machine is stopped, essential for filtering melts with low viscosities like PET and PA. Its unique design offers air cooling at the piston ends, ensuring leak-free operation. With a flow-optimized melt channel, the ESD maximizes throughput up to 2,500 kg/hr while maintaining minimal pressure build-up, protecting both the material and screens during processing. Ideal for applications including plastic bottle production, synthetic fibers, and automotive parts, the ESD integrates into existing production lines to facilitate efficient material purification. Built with approximately 65% effective screen area, this system reduces downtime and enhances operational efficiency in batch or manual operations. Its robust construction suits industries such as plastics, chemicals, packaging, and recycling.
