S. N. Particulars Conventional System VVVFD Concept
1 Initial Investment
i Type of Stator IMCC-HDOL feeder with pro-V VVVFD
ii IMCC HDOL Feeder
01 no HDOL for FAN is
required – IMCC with
pro V
01 no SFU Required for VFD
2 Power Consumption
i Speed Control & Reduction Not Possible Possible 10-110% possible & getting Power Saving
ii
Energy consumption
as per process
requirement
High Energy consumed
as per motor rated KW
Actual Energy consumed
on account of Air Flow &
air Pressure as per Process
requirement.
