You are probably better off having 220v power installed in the new facility.
You're going to have a hard time fitting all the 110v PDUs into the space of the 220v PDUs since 20Amp @ 220v ~= 40Amp @ 110v. You'll need two 20Amp @ 110v PDUs for each 20Amp @ 220v PDU.
If you have eight 110v circuits for each rack, it is trivial for the electricians to combine them into four 220V circuits. I've had the electricians do this many times in many data centers over the years.

We have an R200 in a 42U NetApp rack with 4ea of the 0U, 220v, 16a PDUs. In a few months we plan to relocate it to another facility, but they do not have 220v power available, only 110v. Any ideas where we can find 110v PDUs to replace the NetApp 220v ones? Ideally they would be the same physical size as the ones currently in the rack. They have to be 0U as the rack is totally full.
