Container dehumidifier?

[openspaceman]

As well as insulating it I'd just have a small dehumidifier in there with a hose to drain any water outside.... this is what I have in the sheds/containers where I keep all my gear.

 

Again as with the rope drying thread, this is what I would choose and have chosen for drying kit but if the container is not frequently opened tubular heaters with a thermostat and a little insulation may be more economical. My home de humidifier seems to consume 150 Watts and as long as you set the humidity at just the right point that there is no dripping it should hardly ever come on once the container is shut and the initial load of moisture removed. The danger is with moist air able to diffuse in and keep it running, which not only uses electricity but would shorten the life. I still haven't decided if it makes any difference how high the dehumidifier sits but for convenience mine stays on the floor and drains to a bucket in the room the giant insulated wardbrobe has been built (8' by 4' by 8' high and 100mm of glassfibre between a 4 by2 stud wall clad in 12mm ply) which I hope will accomadate 8 guys' clothing. I have used a Blyss dehumidifier with higher capacity and a built in heater for this but I'm dubious about the quality of the control as it doen't switch on and off like the smaller Delonghi one.

I have one container with sheets of fridge side on the roof. No condensation in this container. The other roof as normal running with condensation inside.

What, the sheets of fridge side are on the outside of the roof?

Good idea. Did you get it all from the local tip?

Most of the storage site that use shipping containers next to each other have the inside of the roofs spray foamed to create the thermal barrier to prevent condesation

Yes 100mm thick plasticote steel sheet both sides. Not designed for roof sheets but bit of mastic between the joints 99% waterproof. The government is giving loans to companies to improve their fridges so the stuff is getting ripped out in vast quanities. Make sure the sheets are not to old as they will not be fire proof. Got the sheets free will try and find a pick. You could do the sides as well and you dont loose space inside.

Not a very good pic but u can see the roof sheet on top which has now been extended across the container on the right and will shortly be across the one on the left.
