The HydroFlex™ units are gravity drainage and forming units located immediately after the Forming Board. These units are equipped with CoorsTek's VersaFoil® blades to allow "on the run" adjustment of the foiling angle, depending on the desired drainage rate and activity levels. The HydroFlex units can be coupled to our GL&V FFS™ controls system to give the papermaker the ability to independently adjust the foiling angle of each VersaFoil blade to optimize stock activity and drainage. Our feedback positioning system allows an accurate and repeatable positioning of each VersaFoil blade. The system will also allow the storage of every adjustable blade position in the PLC memory according to each grade produced for a quick and accurate system positioning when changing grades
As machine speed and basis weight have a direct impact on stock behavior on the table, the HydroFlex Units will insure that the gravity section is optimized for every machine condition.
