BKG® HiCon™ V-Type 3G Continuous Backflush Piston Screen Changer

BKG® HiCon™ V-Type 3G Continuous Backflush Piston Screen Changer

The BKG® HiCon™ V-Type 3G is equipped with a patented POWER BACKFLUSH technology, ensuring the highest efficiency and operating independently of the extrusion pressure.

It is our most powerful backflush melt filtration system - the perfect fit for highly contaminated polymers.

Overview


The BKG® HiCon™ V-Type 3G melt filter is uniquely capable of pressure-constant operation due to its patented Power-Backflush-Technology.

The melt pressure-controlled venting start feature helps you automate and stabilize your process, especially the operating pressure. Constant pressure is one of the most critical parameters in polymer processing systems, especially in the extrusion of film, sheet, and fibers.

Suitable Applications

The BKG® HiCon™ V-Type 3G is an excellent fit for various PET recycling applications.


Bottle-To-Bottle


The BKG® HiCon™ V-Type 3G is the perfect melt filtration solution for removing heavy contaminants while discharging only little material waste when turning used PET bottles into new ones.

Bottle-To-Film


The BKG® HiCon™ V-Type 3G screen changer ensures an even melt pressure and volume flow, which is key in bottle-to-film recycling.

Bottle-To-Fiber


The BKG® HiCon™ V-Type 3G melt filter ensures stable process conditions avoiding fiber strand breakages, which is crucial in sensitive applications like bottle-to-fiber recycling.

Product Testimonials

We design & engineer products that withstand the test of time.


The higher efficiency of the V-Type 3G screen changer means fewer backflushes and less material waste. The system is particularly good in dealing with contamination surges, since the filtration area is regenerated very effectively in a short amount of time.
