Variable-Speed Vacuum Pumps for Energy Efficiency in Dairy Farms

The document discusses energy efficiency improvements in dairy farming, focusing on variable-speed vacuum pumps and heat recovery from milk cooling. It highlights that variable-speed drives reduce electricity use by matching pump speed to actual demand, cutting energy consumption by over 60%. Heat from cooling tanks is recovered to preheat water, reducing reliance on boilers. These measures lower CO2 emissions, extend equipment life, and improve farm productivity. The project is funded by the European Union’s Horizon 2020 programme under grant agreement No 101000770.
