OT: condensation inside shipping container?

How you get rid of moisture inside shipping a container if I would park
a tractor inside with snow on it?

Must be a local thing , I have 4 containers and never see moisture inside them. Most have a small vent in the top corners, are yours vented?

I used to use a 28? as a shed to keep a small loader tractor in. So long as the snow remains frozen it shouldn?t cause issues. Once it warms up enough to melt I just left the door open and it would dry out on it?s own.

I deal with about 50 containers a week, and have never saw a vented one with moisture in it. We do have 3 a week that aren't vented, so we hang Dry Paks on the hooks in the containers.

I have only two containers but when the weather turns cold after a warm wet spell the condensation inside is significant. They are both vented. I think location in the country makes a difference.

I am in a humid area and the container my brother has stored some furniture in for years hasn't had a problem. Venting would help I would think but you have done that. More vents? Insulating might help but that wouldn't be easy or cheap.

use dehumidifier(s)
they plug in and have a drain line you can lead outside through a small hole
they are rated at gallons per day or similar
if one is sorta good get a second

Snow or no snow, during certain weather conditions moisture will collect inside. I occasionally get condensation inside my Morton building, and it has the vented soffit and ridge cap. Only solution is a forced air ventilation system. That is one of the reasons I don't think those shipping containers are a very good idea. Another reason is the cost. You can put up a pole shed for less money.

i have seen some that have had those spinning vents on the roof installed.

Have to ventilate it.

Heat inside that container makes for the ceiling rain condition. I put a heater inside mine once. It rained for three days it seemed.
Insulated containers supposedly do not have that problem. I should have spent more money long ago. Oops.
You could get spray in insulation and that should end the problem.

Here is a 40 I did last summer. You can see a few of the vents in upper and lower corners. I also cut to fit some filter material and inserted on inside of container, helps keep dust out. Gonna do another one this year.

I just put 4 small vents in the sides of mine toward the top and that does a good job of letting any fumes out if they are present.

I'm here in Central Ohio,,just had 3 inches of snow that melted quickly,, I just checked my container and there is moisture hanging on the roof inside,,but the floor is dry..I use it for a "TOY" box and keep my show tractors in it.

The only true way to remove the moisture is with a dehumidifier. It will work best if the container is sealed so more moisture doesn't get in, and insulated to stabilize the interior temperature.

The dripping and water running down the walls will happen when the outside is colder than the inside. The difference is the moisture in the air is being condensed to the cold surfaces. Once the temperature equalizes the water evaporates and is still present as humidity in the air. Same thing will happen if a cold object is brought into a warm area, moisture will condense on the object until the temperature equalizes.

Insulation will help. That way the dripping will stop and the inside temperature will be more stable. The worst situation is when mass (stored objects) cool down over night, and take longer to warm than the air when the sun hits the container. At that point the moisture is attracted to the colder mass, resulting in condensation outside and inside (crankcase, gear boxes, fuel tank, etc) the stored contents.

So, the more moisture that can be removed from the confined area, the better. The down side is in the heat of summer the container can get extremely hot without ventilation. Heat can be just as detrimental as moisture. It cooks the solvents out of plastics and rubber, evaporates fuel and leaves behind residue. That's where insulation also helps.

I would install a power roof ventilator on the top on one end and a gravity damper in the wall on the other end.
