The Hasselblad Xpan (1st version) is not IR friendly. It uses an IR LED and IR photocell to count perforations and thereby count the exposures. IR film in this camera will fog along the upper edge (the bottom of your printed images). This seems to have been solved on the Xpan II.
For IR work, Leica M cameras are ideal: no foam anywhere, no film minder window, IR tight removable baseplate and you can frame and focus even with an opaque IR filter on the lens. The shutter cloth is IR proof: at least I have never experienced fogging through the shutter of my M3. Unfortunately, not all M lnses have the IR focussing correction on the barrel.
