Discontinuous screen changer for low viscosity melts

In the polymer processing industry, maintaining product quality and efficiency is essential, especially when dealing with low viscosity materials like PET or PA. Frequent screen changes without causing leaks or pressure build-up can be challenging, negatively impacting throughput and material quality.

Change screens seamlessly without leaks

The Discontinuous Screen Changer ESD from Econ addresses the specific demands of processing low viscosity melts. Designed to ensure leak-free operation, this screen changer features air cooling at the piston ends, dubbed the ‘ECON thermo sealer’ (ETS). The system allows for screen changes while the machine is stopped, with a piston that moves out hydraulically to facilitate quick and easy screen pack exchanges. The ESD boasts approximately 65% effective screen area, contributing to higher throughput. The flow-optimized melt channels and low pressure build-up protect both the material and the screens, preventing dead spots for faster material changes. Suitable for throughputs ranging from a few kg/hr up to 2,500 kg/hr, it is an ideal solution for industries dealing with low viscosity melts.

Benefits

  • Leak-free operation with air-cooled pistons
  • Higher throughput due to effective screen area
  • Low pressure build-up protects material and screens
  • Flow-optimized design prevents dead spots
  • Wide throughput range from a few kg/hr to 2,500 kg/hr
