BKG® NorCon™ K-SWE-4K Continuous Piston Screen Changer

BKG® NorCon™ K-SWE-4K Continuous Piston Screen Changer

Continuous melt filters from Nordson provide uninterrupted filtration bringing maximum efficiency to your extrusion operation. The BKG® NorCon™ K-SWE-4K is suitable for extrusion, compounding, and recycling applications.

Overview


The BKG® NorCon™ K-SWE-4K model is based on a proven double-piston design with four screen cavities, two per piston. One piston is fully moved out of the housing for screen change; the other remains in the process for process consistency.

The K-SWE-4K model is best suited for processing normal to low contamination levels when your upstream components provide a medium inlet pressure.


Automated Venting

The BKG® NorCon™ K-SWE-4K can be equipped with an automated melt pressure-controlled venting start feature. This provides reliable, repeatable, and independent of material, throughput, temperature, system pressure, and viscosity changes venting procedure, ensuring a high-quality end-product.

Suitable Applications


Extrusion


Whenever virgin polymer melt needs to be prepared for direct extrusion, the BKG® NorCon™ K-SWE-4K is an excellent fit. Removing dust and deposits from transport and storing requires an additional filtration step before extrusion.

Compounding


Equipped with a wear-free sealing system and robust design, the BKG® NorCon™ K-SWE-4K is a suitable filtration system for challenging applications like compounding, where high wear and abrasion are most common.

Recycling


The BKG® NorCon™ K-SWE-4K is highly suitable for recycling processes that require a two-step filtration. Equipped with a coarse screen and placed directly behind the extruder, it filters out very coarse contaminations. This ensures the following equipment is well protected.
