You left out that the glass has to be colder than the ambient air temperature for that to happen. Same with the safe. It's the air at the chilled surface being cooled below its dew point (>100% RH) that causes it to be unable to keep all the water vapor in it dissolved. This is why the Goldenrod type heaters work.
Itar,
If you put the dehumidifier actually into the safe, it won't take long to get the bulk of the water out of the air and that won't be enough to fill the reservoir. But its humidistat will keep cycling it back on every time enough of that water re-evaporates from the reservoir or enough addition moisture dissolves in from the outside through anyplace in the safe that's not hermetically sealed. Similarly, if the air outside the safe is kept dehumidified, moisture in the safe will gradually work its way out.
You may find it less expensive (and less room consuming in the safe) to run one of the heaters inside it, but dehumidify the surrounding air as much as it is in your budget to do.
