BKG® POLY Large Area Filter with Two Pistons for Continuous Operation

Normal operation:
8 screen cavities (100%) in the process

Backflush:
Not applicable

Screen change:
During a screen change two of the screen cavities (25%) are removed from the process, allowing for six of the screen cavities (75%) to remain in operation

The POLY is suitable for almost all polymerization processes (pelletizing, fiber, film). This system enables process runs to continue without any system shutdowns while changing the screen.

Benefits:

  • Low operating costs through the use of low-cost filter media (flat screen mesh); no cleaning and testing of the filter medium is necessary
  • Faster and safer screen change compared to filter pots (filter candles, filter discs)
  • Easy handling during a screen change since there is no need to use a hoist or lifting device
  • Optimized flow channel design (dead spaces free); short residence time eliminates degradation of the polymer
  • Fully automated venting procedure (via PLC) reduces operator intervention

 

Features:

  • ‚Patented technology allows for 6 of the 8 screens to remain in production during a screen change 
  • Eight (8) oval-shaped screen cavities enable a large filter area in a compact and small housing 2 pistons with 4 oval-shaped screen cavities per piston
  • Optimized flow channels utilizing rheological data
  • Wear-free metallic sealing system – no additional seal required
  • Easily integrated into the line controls
  • Includes complete guard system, offering maximized safety for the operators
