At 90% efficiency and with the VFD set at 70%, <br />your savings is 50 kW per month and 100,000 kWh annually. Based on the number of <br />hours of operation, you may be able to increase demand savings beyond 50 kW by setting <br />the VFD to a lower percentage based on the number of hours of operation you furnished! <br />Thanks for helping ERMU conserve electricity. <br />Sinter ly, <br />v <br />~- <br />Vance Ze ger <br />Manager, Key Accounts & Special Projects <br />
