The Benefits of Variable Frequency Drive
The Dri-Flo 2500 features a Variable Frequency Drive (VFD) system, to match the speed of the motor-driven equipment to the drying process, simultaneously reducing operating costs and improving overall efficiency.
When the Dri-Flo 2500 is engaged, the VFD automatically initiates a “soft-start” process to the 30 HP motor running the Dri-Flo’s tapered sweeps and augers, reducing excess power demand when starting the system. The VFD then gradually increases speed to standard operating capacity, minimizing stress on the machine as power is converted from the electric motor to the Dri-Flo 2500’s mechanical components.
The VFD also provides the option of added control while your system is up and running. With an independent display, the operator can adjust the speed at which the Dri-Flo 2500’s sweep augers rotate around the bin. This allows for instantaneous control to adjust removal rates to match drying needs as crop conditions vary from field to field.
As a result of the efficiency gained by the power regulation achieved with VFD in the counter-flow process, many utility providers offer rebates to owners of these systems. Check with your local power company for rebate offers!
