VLT Agro Drive
Three-phase frequency controller

The VLT Agro Drive enables efficient continuously variable speed control of threephase fans. This control is based on a 0-10 V input signal. The fan speed control can
be adapted precisely to the demands of the user. Lower motor temperatures assure
a longer lifetime, less maintenance and higher reliability. Furthermore, the energy
use is strongly reduced. The VLT Agro Drive provides an optimal climate under all
circumstances.
