Otmar;
Excellent cyphering! I new the current draw on a DC motor would be
horrendous but have not had time to research an exact number. I also was
thinking along the lines of a hermetic compressor. As far as check valves
the Sanden already has them built in. I believe all piston  compressors,
just by their nature, have reed valves.
As a further note I would NOT rely on the radiator fan to keep the
condenser cool. If I was going through all this trouble I would  add
another fan in front.
Drive Safely & Good Luck
