VSD for SAB202
Hi everybody,
Have any one try to install VSD on Sabroe screw-SAB202?
What we need to pay attention of?
What is the minimun RPM?
Need to use constant tourque VSD?
Many thanks for your in-put.
Cheer!

Re: VSD for SAB202
I dont know what the minimum RPM is.
A constant torque VSD is definitely needed.

Frgoscandia / England do a similar set with a package. Start at min hertz but have pre-lub oil pump, after timer control load comp to 100% then ramp up VSD to design 50/60 hertz and stop pre-lub oil pump.
