The humidity is already a problem here so need to protect everything inside the vault. Currently I'm using a set of work lights inside to dry the room, but they are good at chewing power.
I've never had anything do to with whole room dehumidifiers before, but from what I read on the net I understand they raise the temp of the room a little.
I like that idea over an aircon because I'm worried about the thought of the guns sweating when they are taken out of an airconned room into the heat and humidity.
I like that the aircon is part of the building and I can set and forget for days at a time.
Remember this is a vault not a gun room, so I'm not in there for long lengths of time.
What do you blokes think is the better way to go?
