From straightforward motor upgrades to installing soft starters, there's an abundance of information out there concerning energy efficiency for plants. But one of the most popular improvements is opting for a VSD. VSDs can effectively control rotating equipment, such as fans, compressors and pumps, in industrial processes. In fact, according to the European Committee of Manufacturers of Electrical Machines and Power Electronics (CEMEP), a 20 percent reduction in speed could lead to a 50 percent reduction in energy. The first step is conducting an energy audit to establish where the most energy is being used in your plant. This will identify the areas with the most potential for energy and cost savings, enabling plant managers to concentrate their resources on the priority areas. So, what should you look out for, if you do decide to opt for a VSD? And if you already have VSDs installed, how can you ensure they're operating effectively?
