An energy saving calculator is available to companies wanting an overview of potential energy savings in their facilities. This convenient tool allows manufacturers to use mobile devices or computers to calculate potential savings derived from variable frequency drives for power pumps and fans. Pump and fan control applications in manufacturing companies make up about 55% of motor applications.

 

This is where significant energy savings can be made, especially if production processes do not need a pressure or flow rate of 100%, which is the case with most pump and fan control applications. Many are still direct-drive applications - in other words, their motors are running at the maximum power levels. However, most of these applications are characterised by variable or regulated speeds that are often controlled by valves and dampers. This mechanical regulation offers a lot of potential for saving energy.

 

Take note

  • Reducing energy consumption by just 1% could be equivalent to saving about 55 million barrels of oil a year, representing substantial monetary value.
  • A company that actively saves energy also scores points in areas of production, operating and environmental commitment.
