screen changer:

good heat and exhaust system, stable pressure system,  more convenient, easy to clean, especially suitable for high transparent and high precision products.

Belt type screen changer : automatic go free operation, the constant pressure net changer, is best choice for flow, BOPP film BOPS.etc.

Special for XPS extruded board screen changer: constant voltage, constant temperature, anti-explosion, does not affect the normal production when change screen, prevent leakage and corrosion resistance.

Application: Sheet, Tubing, coating, lab lines, pipe and profile, wire and cable, compounding, pelletizing (strand and underwater), EVA, hot melt adhesive and PSA, Blown film and cast film, most polymers.

Compounding, master batch, recycling, sheet extrusion, profile extrusion, pipe production, pipe coating, and biaxial orientation.

DEAO is the worldwide leader in filtration equipment, we offer Continuous Screen Changer that provides continuous polymer flow and consistent, repeatable process parameters during screen changes.

As polymer enters the screen changer the melt stream is divided equally and distributed through two theologically optimized breaker plates. This method of filtration provides increased screen area as compared to single breaker plate screen changer designs and maintains a streamlined polymer flow path. Polymer merges back to a single melt stream as it exits the screen changer.

DEAO’s line of High Capacity Screen Changers is the result of 30 years of experience, innovation and development in filtration systems. These Hydraulic Screen Changers are the standard of the industry representing a design proven in a wide variety of applications over a long period of time.
