   It looks like it is not actually a three phase device and it most 
probably can be run on `210 Volta (or so) possibly with the aid of a
buck boost transformer or two.
I would look into the current consumption of the smaller transformers to 
see if they can be paired up to run in series.
I would also look for primary taps on the smaller transformers, if so
perhaps pairs could be run on 240 Volts.  My thoughts.
