Continuous screen changer for thermoplastic materials
Eliminate downtime caused by blockages with a continuous screen changer designed for efficient filtration and backflushing in thermoplastic processes, ensuring uninterrupted production flow and enhanced material consistency.
Filters and Cleans Thermoplastics Continuously
The Screen Changer ESK B from ECON is a continuous double-piston screen changer with a backflush system, specifically engineered for seamless thermoplastic filtration and contamination removal. What sets this equipment apart is its ability to maintain continuous production by automatically redirecting the melt flow, allowing one screen to be cleaned while the other stays active. This results in operational reliability and minimizes thermal variations with its optimized melt flow design.
Ideal for applications in the plastics, packaging, and automotive industries, this system efficiently processes end products such as polyethylene films, polypropylene containers, and PVC pipes, with a throughput capacity of up to 3,750 kg/hr. Its fully automatic backflushing capability ensures significant reductions in stoppage time and labor costs. The design includes approximately 75% effective screen area, minimizing pressure build-up and avoiding dead spots, which allows for rapid material and color changes.
Constructed to meet the rigorous demands of polymer processing facilities, the ESK B can be integrated into existing extrusion lines with ease. The use of durable materials ensures long-term performance and maintenance-free operation, making it an essential asset for thermoplastics processors aiming for optimal efficiency.
