A variable speed drive (VSD) controller for dairy vacuum pumps constantly monitors the air flow needed to maintain a stable vacuum and adjusts the motor speed. By slowing down or speeding up the motor, the pump only runs as fast as necessary. This results in substantial energy and cost savings.
In order to qualify for a reward, the vacuum pump must be controlled by a UL-listed device which meets applicable lnstitute of Electrical and Electronics Engineers (lEEE) standards for harmonic control.
A variable speed drive on a milk transfer pump must be on the receiver jar. May qualify for a custom rebate. Please call 1-866-ALLIANT (1-866-255-4268) for more information.
Earn a rebate of $5 per cow for each one you are milking. The rebate is for VSD controllers only (not vacuum pumps).
