OPERATIONAL SEQUENCE (ESK)

The continuous two-piston screen changer (without backflush) allows the simple exchange of the screens used for filtration during on-going operation. The melt which is distributed in normal operation among both pistons with a screen package each is guided after reaching a defined maximum pressure entirely over the second screen support piston after the hydraulic extension of the one screen support piston. After the exchange of the screen package, the first screen support piston is retracted again and thus integrated in the production sequence again. Then the second piston is moved accordingly.

In order to avoid any trapping of air in the melt (which would lead to a breakage of the filament, strand or film), ECON also offers an automatic venting system for the screen cavities (patented).
There is a large selection of high-quality screen changers for industrial applications which are ideally adjusted to the respective job profile. Tailor-made special designs are available. These include liquidor steam-heated screen changers for quicker temperature compensation for example.

On request we will be happy to arrange a visit to one of our customers, additionally a test run with your material in ECON’s technical centre is also possible.
