Discontinuous Screen Changer ESD

With discontinuous screen changers, the screens are changed when the machine is stopped. The piston carrying the screen is moved out and the screen pack is switched.

For melts with very low viscosity (e.g. PET or PA), the ESD has been further developed to the "ECON thermo sealer" (ETS). This model offers air cooling at the end of the pistons and is therefore leak-free, even with low viscosity materials.

  • approx. 65 % effective screen area for higher throughput
  • flow-optimized design of the melt channels
  • extremely low pressure build up protects material and screens
  • no dead spots for faster material changes

To change the screens the machine has to be stopped. The piston carrying the screen is moved out hydraulically and the screen can be exchanged.


The discontinuous screen changers are appropriate for throughputs from only a few kg/hr up to 2,500 kg/hr.
