Which is to say, not very far on this at all but I think I have a good idea on how have my cake and eat it too for desiccant for my spools.
I am finding I can’t get the humidity below about 50% in my AMS and the silica I am using needs constant refreshing.
Well it seems there is stuff called activated alumina that is pretty good and honestly about the same costs as silica beads, but I need to be able to put it in the oven to refresh it. Which doesn’t work well with my 3d printed desiccant holders.
Insert, cheap tea strainers.
It seems I can get ones that are 4cm in width by 6cm in height that are made out of stainless steel that I can actually put straight in the oven.
So, I am working on getting the parts and items but was wondering if anyone else has done this or have any suggestions before I start grabbing stuff?
@Krauerking @PlasticExistence they’ll have subtly different drying profiles. Silica gel had a higher capacity but will maintain a generally higher relative humidity. Check the graph here out https://www.impakcorporation.com/desiccants
Activated alumina doesn’t appear to be as effective as molecular sieve at low humidity from a lit. search.
You should check for air leaks in the system first. When I lose Desiccant this is usually why.
P. S. Silica gel can be regenerated.
