Fortunately, there is a solution: Variable speed drive (VSD) compressors.
They don’t always produce as much air as you need on your busiest day. Instead, they always produce as much air as you need right now. As a result, variable speed screw air compressors significantly reduce your energy costs.
To find the right model, you have to determine the peak and valley value of compressed air consumption. That helps you monitor and measure how much electricity you need to generate all the compressed air that you need. For this, you have to calculate the Specific Energy Requirement (SER), which means the amount of energy that is required to deliver 1 liter of free air delivery (FAD) at a certain pressure.
Finally, VSD screw air compressors impress with a wide turndown ratio. Turndown is the fraction of full-load flow that a compressor can handle without experiencing a surge. A wide turndown ratio means there is a large operational range between their maximum and minimum capacities.
With all of these benefits, it’s easy to see why Atlas Copco’s VSD screw air compressors are a popular choice for businesses across all industries.
