A new tool from Rockwell Automation allows manufacturers to use mobile devices or computers to calculate potential savings derived from variable frequency drives to power pumps and fans. Manufacturers can use the online energy savings calculator or download the free mobile application to their iPad, iPhone, Blackberry or Android systems.

With this new tool, users can compare conventional methods, such as valves for pump control and dampers for fan control, to variable frequency drives and see estimated cost savings of installing an Allen-Bradley PowerFlex drive. The tool offers two ways to calculate energy consumption. Users can enter the minimum pump or flow percentages, annual operating hours, cost per kilowatt and other information about their own factory, or use the sample data provided by Rockwell Automation built into the tool.

Doug Weber, Rockwell Automation business development manager, says: “Now manufacturers can quickly and easily plug in information about their own systems to discover energy-saving opportunities, often the first step in pursuing them.”
