Proper tank storage

[Brilig]

I saw a thread the other day asking people how many tanks they owned and how they stored them and it got me thinking. I have two new steel HP 100s and an aluminum 30cf. I store them in a climate controlled area but have considered storing them in an outdoor shed. The shed would subject them to temperature swings from below zero to as high as 100 F seasonally. I worry that any moisture within the tank could condense with temperature change and cause corrosion.
What steps do LDS's take to minimize moisture in the fills. Am I just over thinking this?

Do not store your filled tanks out in the sun.

Other than that, they're metal cylinders. Al is pretty much foolproof. With steel, corrosion happens - but the way to prevent it is to make sure there's no moisture within the tank. A proper shop fill will be dry.

A lot of yardsale find tanks are fine after a few decades of neglect provided it's dry air inside... Seems a dry shed is fine to preserve the outside.

@Briig No issue storing them in the shed. Get your air from a reputable dive shop and you are all set. I have steel tanks that over 30 years old and they are fine.

Thanks for the fast response. This will free up some space in my workshop.

A tank at high pressure will hit the dewpoint of the gas as you get below 20 deg F even with air dryer than most shops put out. A -60F dew point is dry scuba air but it will condense above 30 deg F.
