An online and mobile estimating tool from Rockwell Automation allows plant engineers and managers to calculate savings from implementing variable frequency drives to power pumps and fans.
Engineers can use the online energtool or download a free mobile application to their iPad, iPhone, Blackberry or Android device. Users can compare conventional methods – such as valves for pump control and dampers for fan control – to harnessing variable frequency drives, and see estimated cost savings from installing Allen-Bradley PowerFlex drives. You can enter minimum pump or flow percentages, annual operating hours, cost per kilowatt etc.
