Moisture condensation
Moisture condensation
(OP)
Hi everyone,
I'm trying to find a way to reduce or even disappear moisture from a vault and i hope someone can help me.
During days with high humidity in the air, and when air temperature is lower than 15 C (observation), water droplets are formed inside the vault just under the doors (manholes), which drop on the floor and corrode the metal fittings. This is most probably caused by humidity in the vault, which is condensed when in contact with cold surfaces (vault ceiling and doors).Keep in mind that the doors open once a week for an hour for inspection reasons.
Is there any tested technical solution to absorb humidity?
[Consider an underground room (vault) with two manholes to enter on the ground level (dimensions 1m x 2m made by cast-iron). The dimensions of the vault is aprox. 7 m debth, 5m width, 5m length. The vault's ceiling,bottom and walls are concrete.]
Thanks in advance,

Something that i did not mention is that any device installed in the vault must be ex-proof.
I wonder if the dehumidifiers or the space heaters are ex-proof.
Thanks in advance

We use explosion proof lighting fixtures. Incandescent bulbs are fine.
Keeping a light on does wonders.
