Yes Sir!  The (Container Storage) Vents are just what the Dr. ordered!

I installed everything last Saturday. I took my first reading yesterday early evening. The outside temperature was 100 and RH was 67. Inside the container the temperature was 108 and the RH was 37. This morning the outside temperature is 74 and the RH is 97. Inside the container the temperature is 77 and the RH is 54.

Thank you!

Note from 360 Products: On a 40' container, John used a wall exhaust vent on each of the 2 entry doors and a single back wall intake vent to achieve these results.

"I have no problem with you sharing our feedback, especially to fellow Naval personnel. [Y]ou'll be pleased to hear that my supervisor had a chance to see the finished product after the install I did, and he is very pleased that not only the obvious functionality of the vent (feeling the breeze, he said), but also the aesthetic look the[y] add. We are definitely satisfied with your product and would recommend it to anyone in need of such a thing."

A large steel box is a perfect environment for condensation.  Heat and humidity are big factors but in most cases can be controlled without power, The more contributing factors found in the "8 steps to a dry container" text above that can be addressed, the better your results will be.

There are many variables and every geographical location is different.  There is no one perfect resolution.  This makes it even more important to read the material provided on this site and see what combination best fits your own situation.  Please do not hesitate to call us if you have any questions.  That's why we publish our personal contact information and do not use call centers.
