How can variable frequency drives help industry to make cost savings as well as secure environmental gains by reducing emissions? Louise Davis fi nds out
ritish electric motors and drives expert Invertek Drives has long known that a critical market
diff erentiator for its products is the impact they can deliver in terms of energy eff iciency and sustainability. Kes Beech, Technical Manager, says: “Invertek Drives is at the forefront of demonstrating how variable frequency drive (VFD) technology is pivotal in achieving signifi cant cost savings and supporting environmental sustainability across industrial applications globally.” Beech explains that, “One of the most compelling ways VFDs, such

as our Optidrive range, contribute to cost eff iciency is through substantial energy savings. By precisely controlling electric motor speed to match actual demand, VFDs eliminate energy waste prevalent in traditional fi xed-speed (Direct On Line) motor set-ups.” What this translates to in real-
world applications is potential energy savings of up to 50% in certain applications, such as pumping and fans/ventilation – a benefi t that directly impacts the bottom line for businesses. “Furthermore, the smoother starts and stops facilitated by VFDs minimise mechanical stress
on the equipment, leading to reduced wear and tear. This leads to extended equipment lifespans and decreased maintenance costs, adding another layer of fi nancial benefi t,” Beech notes. Another advantage is the precise
speed control through VFDs enables process optimisation, leading to increased productivity and potential cost reductions across various industrial operations. Beech is also keen to point out
that the merits of VFDs go beyond fi nancial savings. “The environmental sustainability aspect of VFDs is equally important,” he states. “The reduced energy consumption resulting
