VFD on 600HP centrifugal Compressor
VFD on 600HP centrifugal Compressor
(OP)
Hi all,
Is that possible to apply VFD on 600HP centrifugal air comrpessor? It is 460V and using inlet and bypass valves as the control.
Also, what would be the other methods to control and saving energy?
Thanks in advance.

To avoid risks of premature motor failure, verify that the original manufacturer considers it “VFD Duty Type”.

The only thing I'll add about air compressor retrofits is to watch out for minimum speeds with regards to lubrication. Some machines use mechanically driven lube pumps which stop working below a certain speed. If it is a problem, many people just replace the lube pump with an electrically driven constant speed version.

One place raved that they are going to have less than a year ROI for a 30HP they just installed.
