PSI manufactures Discontinuous Screen Changers for processes that can endure a very short interruption of the melt flow. Its compact design permits simple adaptation and flexible installation. The screen change procedure is performed when the extruder is stopped. The DSC is an automated alternative to the Manual Screen Changer or In-line filtration. PSI Discontinuous Screen Changers can be designed to allow the extruder screw to be pulled through the screen changer without removal. PSI guarantees leak-free operation up to 10,000 psi and 650° F.
