Hitachi America, Ltd.: Hitachi HiSave Energy Saving Estimator Software
Hitachi provides a software package HiSAVE VFD (Variable Frequency Drives) Energy Savings Estimator that is primarily aimed at HVAC and Pumping customers, but industrial customers may benefit from it as well.
Its purpose is to help users estimate what electric energy cost savings would be realized if they installed an inverter (VFD) to replace older mechanical means of regulating air/fluid flow. HiSAVE also includes useful tools for calculating horsepower and torque as well as AC Induction Motor speed/slip Three-Phase Power and Ohm's Law calculators.
Compatible with Windows 2000 & XP the software is a FREE download from the Software Downloads area of www.hitachi.us/inverters, and requires no additional software or hardware to use.
