Advantages

Significantly improve heat transfer rates of polymers and other viscous products. Three to seven times the rate obtainable compared to an “open tube” (no blendrex® elements) design
Provide a shorter product residence time inside the unit
blendrex® tube is a “plug flow” device
Tubes eliminate localized “hot spots”, and provides uniform temperature profile across the tube section
Contain alternating helical twist elements to obtain the high performance capabilities
