Discontinuous hydraulic single piston screen changer
max. 2500 kg/h | ESD/ETS series ECON GmbH

The discontinuous ECON single-piston screen changers are efficient, reliable and leakage-free. They are also suitable for low viscous materials such as PET and PA. The special permanent air cooling seals the gap at both ends of the piston and thus prevents leakages under highest process pressures. Optimized flow channels protect the melt, avoid clearances and produce a low pressure build-up.

ADVANTAGES
• Processing capability of thermoplastic materials of even low viscosity - PET, PA
• Entirely free from leakages through air cooling at piston ends
• Approx. 65% effective filter surface for more throughput
• Flow-optimized design of the melt channels
• Extremely low pressure build-up protects material and screen
• Freedom from clearances speeds up change of material and colors
• Low expenditure for power, staff and maintenance
• Low investment costs, rapid amortization
