Condensation In Shipping Containers, A Problem Or Not
Thursday, 15th October 2009
Condensation can occur inside shipping containers. For anyone using or operating them for self storage this can be a worry. Warm air contains more moisture than cold air, this moisture gets into the container either from the outside or from evaporation from the goods stored inside.
Damage from condensation can range from very minor issues such as mildew spots and labels peeling from packaging to more severe issues, if the problem is allowed to go unchecked for long periods of time.The worst time for condensation is winter. During the colder months the temperature outside the container falls much quicker than inside.
The issue of condensation is however easily addressed. Ventilation is one way of helping to reduce the problem. You should always make sure any vents in the container are not blocked by the contents or taped over. When used for shipping quite often the vents will be taped over for fumigation and not always removed when sold. Additional vents can also be fitted at little extra cost, some new containers come with 10 vents instead of the usual 2. Opening and closing the doors at regular intervals will also help to air the contents, however this may not always be a practical solution if your goods are stored abroad for example.
Insulated containers are an option which offers reduced condensation, however it is a popular myth that they will completely eradicate moisture inside.
Silica gel bags or poles are a very good solution. They will actually absorb condensation from the air before it damages the contents. The correct amount of bags or poles for the size container you are using need to be inside and they must also be changed according to the manufacturer’s instructions to ensure you get the best from them.
