Jan. 5, 2024
New features include an improved head design, a separated control cabinet and more positions for the operator panel.

ZE 28 BluePower KraussMaffei’s well-established BluePower line of twin-screw extruders is known for its energy efficiency. Responding to the requirements of its customers, KraussMaffei has updated the design of its ZE 28 BP extruder, which can be used for small-volume production or laboratory lines. It has a free volume outer-diameter-to-inner diameter (OD/ID) ratio of 1.65, an L:D ratio ranging from 32:1 to 64:1, and can add up to three side feeders.  

What’s new? The updated ZE 28 BluePower, which debuted at Fakuma. New features include an improved head design that offers better protection of electrical parts and simplifies cleaning, as well as a separated control cabinet that improves protection of the electrical equipment. The standard version also adds two more optional positions for the operator panel, allowing the machine to be operated from the left or right side. 

Benefits A more attractive price and shorter delivery times. The machine is equipped with KraussMaffei’s pioneer processControl HMI software, which can provide step-by-step instructions for procedures such as starting the production line or shutting it down. In addition, common upstream and downstream systems can be integrated into the new control system.
