Variable Speed Drives (VSDs) are pieces of equipment that help to control the speed of machinery.

Variable Speed Drives (VSDs) or Adjustable Speed Drives (ASD) are pieces of equipment that help to control the speed of machinery. VSDs and ASDs can be vital to industrial applications. Many processes need to operate at varying speeds, depending on the product.PSI’s Variable Speed Drives are most typically used in pumps, compressors and fans, but can also be applied to many other types of equipment. There are many benefits to using VSDs and ASDs, including a rise in productivity and a saving in energy.

How are the Speed Drives really useful?

Using the three examples listed on the right, variable speed pumps help to save energy by:

Fans: Reducing the speed of the fan is a much more energy efficient way than dampers to regulate the output of fans.

Pumps: Using a variable speed drive to control the pump rather than using simple throttle control can result in significant power SAVING.

Air Compressors: The potential for energy savings from using VSDs for air compressors will depend on the control system being replaced.

Where the Speed Drives are really useful?
  • Fans
  • Pumps
  • Air Compressors
