Investing in new efficient pump and fan systems provides the opportunity to achieve large energy savings and to minimise total life-cycle costs.
System changes might be triggered by changes to manufacturing processes, increasing or decreasing flow rates, equipment wear or failure or lack of spare parts. Even without these triggers, the potential energy savings justify investigating upgrades or replacement of an existing, functioning fan or pump system.
Further fine tuning through eliminating unnecessary flow paths, reducing excessive frictional losses, improving inlet and outlet conditions and maintaining performance can also save energy.1
Some examples of opportunities in this area are outlined below.
