Driving down energy use

With Danfoss variable frequency drives, energy consumption shrinks geometrically

To create impressive energy savings, it takes deep insight into the physics of energy consumption. That's why advancements in energy-efficient drives and pumps take advantage of Affinity Laws -- mathematical formulas that describe the relationship between speed and power. Theoretically, power consumption in rotating machinery is directly proportional to the cube of speed -- which means reducing speed by 20% could produce energy savings of nearly 50%. Putting theory into practice, Danfoss draws on four decades of practical experience in water/wastewater and HVAC applications to create the broadest array of variable frequency drives (VFDs). By varying the frequency of electrical current supplied to the motor, Danfoss VFDs can reduce a motor’s rotational speed to match the workload more precisely -- which multiplies energy savings. Count on Danfoss EnVisioneering to help you create an efficient solution that delivers a real competitive advantage in a constantly changing world.
