UPS + Cold Weather Conditions
(OP)
I am looking for a mfg. for a UPS rated for -25 deg C - Has anyone ever come across this before?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Specs say it's good down to -18 deg C. I have no experience with these, so better check it out closely.
Good luck,

You need a fan and a little heater. Normally neither need run but if the space gets too warm because the UPS is running, or battery charging, you turn the fan on and if it gets too cold like under about 35F you turn on the heater. This also lets you use any UPS rather than one that may cost a premium to give you 10% of its capacity at a low temp. The temp control an be very rudimentary since you can have a dead band of about 40 degrees.

The flywheel solution is definitely technically feasible but financially feasible is another question. By the time that you buy a flywhell system you probably could have heated the entire room let alone just the enclosure for the UPS. Depending on the length of time the UPS is expected to run you shouldn't have to worry about it becoming cold in the backup scenario since just operating the batteries will keep them somewhat warm, 90 minutes shouldn't be a problem.
