The SMI version of our premium ZIP screen drive for use in a KNX system. When it comes to the automation of ZIP screens, this drive is setting standards: Becker engineers used state-of-the-art software to implement sensitive detection into this application involving flexible fabric. The intelligent nature of the S18-ZIP screen drive also ensures that the fabric is always pulled tight and that any natural changes in the length are compensated for. On the other hand, the fabric untensioning function can also be activated so as not to put unnecessary strain on the sensitive fabric. After all, there was one goal that we always had in mind when developing our drives: to make the operation of the application and the drive as careful as possible so you can enjoy your products for a long, long time.
