Variable frequency drives - Import export

Totally independent Aerator and Mixer. Air Provided by Blower with Variable Frequency Drive which can regulate oxygen supply from zero to maximum capacity; whilst retaining full mixing and oxygen dispersion capability therefore the units are ideal for SBR ASP & MBR applications.

With Conventional Feed Lines, the focus lies on speed and material surface. That’s why Conventional Feed Lines are equipped with a Coil Reel for pull-off, a Straightener with variable frequency drive a coil loop and a Servo Roll Feed: the loop uncouples the more inert straightening process from the highly dynamic indexing process and thus allows for high line speeds and preservation of the material surface. Since productivity and capacity demands can vary significantly, we have created different control concepts: while small Feed Lines work with a simple pneumatic drag brake at the Coil Reel and an ultrasonic sensor to control the Straightener speed, the large Feed Lines get fully synchronized controls with motor-limited Coil Reels and a smart loop, creating a steady average speed of the whole line. This allows smooth pull-off of high coil weights while the loop remains very calm – in addition, the Servo Roll Feed can work with full dynamics, even at long indexing progressions.

The machine is intended to knead various types of high viscosity dough at confectionery and bakery enterprises: •gingerbread dough; •dough for doughnut products; •dough for sugar cookies; •dumpling dough, etc. The dough dish overturns through 120 degrees to unload the dough. All dangerous points of the machine are guarded. When the cover is open, the vane drive motor is automatically shut off. The feature of the dough-mixer is its powerful Z-shaped blades of stainless steel that enable to knead the tight dough gently. A variable frequency drive is used for smooth change of the blade rotation speed that makes it possible to use the machine for kneading crumpet dough.

Demag frequency inverters ensure that your motors deliver the performance that you expect. We offer solutions for virtually all drive applications with our Dedrive Pro 880 and Dedrive Compact STO ranges, to meet even the most demanding requirements. Dedrive Pro 880 and Dedrive Compact STO provide optimum utilization of motor output for variable speed control. The starting current is limited and, at the same time, the motor and gearbox loads are reduced – any mechanical elements (including the crane girders and crane runway) are protected and loads are transported smoothly and gently.
