Milk Pumps

Milk pumps in dairy milking facilities move the milk into a plate cooler before it flows to the mechanical cooling system. The variation in the milk flow during the milking process reduces the effectiveness of the heat transfer across the plate cooler heat exchanger fins. A VFD or VSD controls the milk pump for a slower and more consistent flow of milk through the plate cooler, which reduces the refrigeration compressor’s run time. VSDs or VFDs installed with existing milk transfer equipment, or installation of new milk transfer equipment with a VSD/VFD, are eligible for a rebate.
