VARIABLE FREQUENCY DRIVES
VARIABLE TORQUE VFD Requirements: • Water System includes any direct well water pumping for waterer or cleaning needs, as well as distributing the warm water from the output of a well water plate-cooler for reuse purposes. • Process Pump category can include a slurry pump or other process driven pump needs on a farm. • VFD must be installed on a centrifugal or axial flow pump or fan, i.e., a variable torque load used to control a process on your farm. • Routine replacement of existing VFDs do not qualify. • Individual motors controlled by a VFD may not exceed 500 hp. VFDs controlling motors larger than 500 hp may be eligible for a custom incentive. • VFD speed must be automatically controlled by differential pressure, flow, temperature, or other variable signal. Units installed only to allow soft starts are not eligible. • The system controlled must have significant load diversity that will result in savings through motor speed variation. • Rebates for Ventilation/Circulation Fan VFDs (MMID AG3777) are not available in addition to Ventilation Fan with VSD rebates (MMIDs AG5089 and AG5095) on page 23.

CONSTANT TORQUE VFD Requirements: • VFDs must be installed on constant torque equipment (e.g. conveyors, augers, positive displacement pumps, extruders, mixers, centrifuges, crusher/shredders). • Individual motors controlled by a VFD may not exceed 500 hp. VFDs controlling motors larger than 500 hp may be eligible for a custom incentive. • Rebate is based on motor horsepower controlled by VFD. • VFD speed can be automatically controlled by differential pressure, flow, temperature or other variable signal, or manually controlled. • Units installed only to allow soft starts are not eligible. The system controlled must have significant load diversity that will result in savings through motor speed variation. • Air compressors are not eligible for this offer. Instead, use the "Variable Speed Drive Air Compressors" on page 12 of the Process Systems Rebate Catalog.
