ABB has developed calculation tools for estimating the energy savings that become available when applying electric speed control to certain flow machines. Using PumpSave and FanSave tools, AC drive control in pumps and fans can be compared against traditional flow control methods in terms of energy usage. The tools also provide financial figures for assessing the profitability of purchasing an ABB drive. PumpSave and FanSave run in Microsoft Excel and utilize VBA macros.
PumpSave 4.0 Energy Saving Calculation Tool (xls, 0.74 MB) - for comparing AC drive control against throttling, on/off and hydraulic coupling control in pumps. Calculate how much energy and money you could be saving with ABB drives while also deriving other benefits such as soft starting and stopping, an improved power factor, and connection into process automation. PumpSave also carries out a simple dimensioning and recommends an appropriate ABB drive type.
FanSave 4.0 Energy Saving Calculation Tool (xls, 0.74 MB) - for comparing AC drive control against traditional flow control methods in fans. Calculate the savings you can achieve by replacing outlet damper, inlet vane or pitch control methods with electronic speed control from an ABB drive. FanSave also provides financial and environmental figures concerning the control method retrofit project and recommends a suitable ABB drive type.
