The Ultimate Screener™ is designed by utilizing the effect of a natural phenomenon known as "the Strange Attractor". The effect of this phenomenon, which is described below, is widely used in the design of electronic devices, especially amplifiers, but was until recently considered imapplicable to mechanics. Kroosh Technologies boasts of the first and only application of this effect to a mechanical system and is the proprietary owner of the mathematical model for this application.

The Strange Attractor has the effect of keeping the vibratory system in a resonance mode, regardless of its starting position and/or of any changes to external influences to this system while it is in operation. In other words, the strange attractor effect determines the strong non-linear character of a vibratory system and stabilizes this system in the resonance area (Fig. 1)

ULS - Ultimate Screening Machines

In January 2010 Kroosh was renamed Virto after a purchase/merger with Cuccolini was completed. Virto is represented in North America by our sister company Virto/Elcan.  Please find their website link below, to learn more about the complete line of ScreenX Vibratory Screeners.
