Now I understand what you mean about regenerating the desiccant. Together with a humidity sensor, hopefully the rust problem can be addressed. Thanks!

It's hard to gauge how often you will need to change it out. It might be worth having a dehumidifier, or at least a sensor monitoring the humidity in the room to give you an indication of when the desiccant has stopped doing it's job.
It will also help with the moisture that isn't being absorbed. Then like I said you should be able to place the desiccant on the hot side in the path of the airflow and the warm air should remove the moisture and exhaust with the hot air. This is the process of regenerating your desiccant. You would pretty much just repeat this process as often as is required.
Like I said I've never personally set this up but I think it would benefit you and your machines, hopefully it works out well for you.
If you don't mind me asking are you near the coast in BC is that where the problem is coming from ?

Well, it's hard to give a solid answer without much info. What are the details of your setup?
... Again I don't know what you have for a set up but this would cut down on the moisture in your air enough that it should no longer be a problem for your miners.
Thanks for the suggestions so far, I should have clarified a bit more at the beginning. Local ambient air enters through approx area 300 m^2 and is exhausted at a rate of ~1k m^3/s.You could have a wire rack at the air intake with these packets hanging off it.
Probably the easiest solution, how often to change the desiccant though? I really appreciate this suggestion, but I don't understand where exactly you're thinking the dessicant would be within the intake process? The cooling process is passive, with ambient air entering a colder side, where it is run through the miners and exhausted again. The airflow is much too great to not have the dessicant inline somewhere, but it doesn't seem practical to have it right in front of the miners' intake fans. Perhaps lining the walls with dessicant breathers/filters is the best solution.
Yeah, you definitely don't want them near the intake for the miner itself.
What I'm suggesting is where the intake air for your mining room is should have the desiccant located there. This way as the air enters the room the moisture is removed. You could have a wire rack at the air intake with these packets hanging off it. Again I don't know what you have for a set up but this would cut down on the moisture in your air enough that it should no longer be a problem for your miners.
good luck
I don't know what your set up is. If you feel a dehumidifier can't keep up have you thought about placing a dessicant inline with your air intake?

I've never had to set anything up like this myself but it's what is used in boilers to prevent moisture.
What ever it is that you use if you have a hot side to your setup you can use the exhaust air to regenerate your dessicant.

I think there might be too much airflow to use traditional dehumidifiers. Even a large-scale dehumidifer like the dd1200 processes less than 1000 CFM. Compare that to a single antminer s9, which moves at least 100 CFM.
Would a ratio of, say, 1000 CFM dehumidified air + 9000 CFM ambient air be enough to have a noticeable difference on 100 miners? Or is there some easy solution to this problem that I am missing?

Put a dehumidifier in the environment - keep the humidity down.
You have too much moisture in your environment..
Although initially only the fan grates seem to rust, eventually the controller board rusts dead as well. What are some effective ways to slow or stop the S9 from rusting?
